Talking about the current development of corn processing equipment business

With the continuous development of the Belt Conveyor industry, market development scale corn processing equipment business is growing, the numbers are increasing, and promote the rapid development of the domestic processing industry. Development of corn processing equipment, greatly improving the utilization value of corn, raise the level of the overall development of our national economy, with good market sense.

In recent years, Hammer Mill processing equipment enterprises to actively expand the production scale, has yielded some benefits, but the development of corn processing equipment industry has unbalanced situation, a single product of corn processing equipment, technical level is not high, restricting the overall development of the corn processing equipment industry level. Throughout the development of China's market corn processing equipment industry, mainly characterized by the following three situation:
First, the market is volatile. In early development, the development of corn processing equipment industry is affected by the downstream supply of raw materials, the supply and demand of corn market directly affects the operation of corn processing equipment. Affected corn futures prices, corn processing equipment, poor product sales, backlog serious losses surge, various economic indicators are significantly decreased. Late corn processing equipment business to retain market share, increasing production technology, reduce production costs, corn processing equipment market remained relatively stable.

Second, two differentiated products. On the whole, although some corn processing equipment business achieved good economic benefits, but mainly rely on fuel ethanol profit structure. Corn processing equipment began to adjust the industrial structure, corn processing equipment business polarization serious efforts to fuel ethanol production increased, relative to other products on the market downturn, leading to the development of corn processing equipment industry imbalance.

Third, the industry recovery is slow. From the annual corn processing equipment business trend, although there is some corn processing equipment market recovery rally, but overall demand does not change much. Under the pressure of competition in the domestic market, the development of domestic corn processing equipment difficult.

In summary, there are corn processing equipment business irrational industrial structure, market instability and other problems in development. Therefore, corn processing equipment companies to develop a reasonable model of development, maintain a reasonable development of corn processing equipment industry. At the same time, should the overall development of corn processing equipment products, continue to diversify, corn processing equipment to achieve stable and healthy development of enterprises.

Conveyor belt rules

( 1 ) belt conveyor installation method should be required to install a fixed basis. Before moving belt conveyor officially running wheels should live with a triangular wedge or stopped with the brake . In order to avoid

( 9 ) belt conveyor motor must be well insulated . Mobile conveyor cables do not Luanla and dragging. Motor should be grounded.
( 10 ) non- slip hand to pull the belt when the belt in order to avoid accidents.

Maintenance of the conveyor

In order to ensure reliable operation of Ctgrain Grain Conveyors  the most important is the timely detection and troubleshooting that may occur. For this reason the operator must always observe the work of transport, such as abnormal should timely manner. Mechanical workers should regularly inspect and examine any circumstances or components should be noted that this is very important. For example, a roller, does not seem very important, but a high-speed conveyor belt conveyor wear materials may soon put its shell worn out, the emergence of a blade, the blade could seriously damage an expensive conveyor belt. Workers trained or experienced staff to detect impending accidents and preventive measures. Conveyor belt conveyor in the entire conveyor costs account for a large proportion. In order to reduce the cost of replacement and repair conveyor must focus on operations and maintenance personnel training in the operation and maintenance of the conveyor of knowledge.

Food conveyor belt running deviation and skid processing method

First: spiral hydraulic tensioning belt conveyor tensioning or skid using spiral tension or hydraulic tensioning appeared sliding adjustable leather belt conveyor tensioning trip to increase tension. But, sometimes the tension line cheng is not enough, created permanent deformation belt, the belt can be cut to a sulfide back into line.

The second: in the use of nylon tape or EP is required tension travel is longer, can also be used when insufficient trip to sulfur or increase the tension to solve

Third: heavy hammer tensioning Belt Conveyor  belt skid to use heavy hammer tensioning device of belt conveyor in the belt creep can add weight to solve, when added to the belt does not skid. But should not add too much, lest make the belt to bear too much unnecessary tension and reduce the service life of the belt.

The friction belt conveyor driven workflow

The  Belt Conveyor is used in all walks of life, such as power plant coal conveying, steel mills and cement plant material conveying, loading and unloading, etc and the port within the ship by belt conveyor. According to the requirements of process flow, the function of belt conveyor by material from one or more points is very flexible, can also turn to more or a few segments discharge. When feeding on a few points to the conveyor belt at the same time (such as coal preparation plant of coal under the conveyor) or a little along the length direction of the belt conveyor by uniform feeding equipment to transport brings, belt conveyor has become a major transport corridors.

In the process of using belt conveyor to note:

1, the throughput is in the material density of 1.0 t/m3-1.6 t/m3, conveyor inclination of 18 ° or less, under the condition of material accumulation Angle of 30 °.

2, may transport the material density under 2.5 t/m2.

3, delivery length is not limited to the values listed in the table, we can manufacture according to the needs of the users. 

Belt conveyor reducer broken shaft failure analysis

Belt Conveyor gear reducer occur at off-axis high-speed shaft , the most common is to use the first level is the vertical gear bevel gear shaft speed shaft . The main reasons are :
First, the speed reducer shaft design strength is not enough
Generally occurs in the shaft shoulder broken shaft after fracture usually flush . Because here there fillet vertical vibrating conveyor , prone to fatigue damage, such as rounded corners make the gear is too small in a short period of time broken shaft . This happens should be replaced or modified gear reducer design.
Second, the high-speed shaft misalignment
    In most cases do not occur off-axis motor shaft screw conveyor , it is because the motor shaft materials are generally 45 steel , motor shaft fairly thick, stress concentration is better, so do not usually break the inertia motor shaft vibration conveyor. Motor shaft and reducer speed shaft misalignment causes the input shaft when increased radial load , increase the bending axis , long-term operation will occur off -axis phenomenon . In the installation and maintenance of its location should be carefully adjusted to ensure that two concentric shafts .
Third, the dual motor drive in case of off-axis
   Belt conveyor drive past without using fluid couplings are more prone to this type of situation , because the two motors run at startup and speed synchronization and the force balance is difficult to guarantee . Dual motor drive is on the same drive gear equipped with two rollers and two motors. Now, most have adopted a fluid coupling less off -axis phenomenon occurs, but should pay attention to the amount of fuel coupling can not be too much , so it has a torque limiting coupling effects and improve the life of the vibrating conveyor . High-speed shaft of the gear unit design or selection of smaller margin more likely to occur when the phenomenon of broken shaft .

Accident Analysis and Prevention Belt

Underground mine belt conveyor is mainly fire-prone areas, because of its sudden, rapid development, pose a threat to the underground workers, and even induced due to the spread of fire and gas explosion is possible. Result in a fire accident was caused by the ignition source has enough calories to make tape burn. Skidding accidents are a major factor in generating enough heat, tape slippage is due to loose or tape jam large load caused by the tape tensioning device due to loose tension force generated by the elastic elongation of the tape is too small and too large; large load First, because of heavy start, the second is due to load is too large, three is the tape and active roller, driven roller idler friction between too small, such as tape inside surface water or oil, the driven roller bearing damage or childcare roll damage; tape jammed tape is mainly buried in coal or in the mud, so that the tape can not run. Another electrical equipment sparks, electrical short circuit may also cause the conveyor fire.
1.2 belt run cause of the accident
Runtime Belt Conveyor deviation is the most common faults. Deviation accidents occur frequently, it will affect the life of the conveyor, severe outage occurs or is likely to result in personal injury or death. Causing belt run three main reasons: First, the device itself aspects, such as the outer cylindrical drum larger error, roller rotation is not flexible, proactive and driven roller drum axis parallelism error is larger, etc.; Second, installation and commissioning aspects, such as roller, roller, rack installation does not meet regulatory requirements, in addition to vent coal biased position of the mouth, causing the tape to make partial load deviation; Third, maintenance, mainly due to the cleaning is not timely, transport Machine Drum Machine roller-stained dust, resulting in local diameter Ambassador belt run.
1.3 Tear cause of the accident
Tear tape main reasons: First funnel badly worn, resulting in waste rock and coal gangue direct hit tape or card tape and other items caused by tearing; Second, serious deviation is scraped tear tape; three tape joint strength is too low or because the load is too large to make tape joints broken.
Prevention
2.1 Fire accident prevention
1) using fire-retardant tape, even in the event of fire, it will not be able to control the fire rapidly.
2) strengthen the maintenance of electrical equipment, to prevent fires caused by electrical accidents.
3) strengthen management, to keep the roadway clean, tape no floating coal, water, no oil, no debris, nose, tail no heap coals. Improve the quality of operation and maintenance personnel to maintain good running condition conveyor.
4) conveying confidential installation inspection and monitoring devices, such as drive rollers and driven roller temperature monitoring devices, smoke alarms and fire in the event of an automatic sprinkler system.
2.2 Deviation accident prevention
1) confirmation by the state purchase of qualified products, avoid the lack of precision equipment manufacturing belt deviation caused by an accident.
2) Install the installation process to focus on the dimensional accuracy:
a. installation tape found at the deviation in the drum, the drum should be corrected and equal degree of levelness, drive pulley, steering cylinder installation requires its width tape centerline coincides with the centerline of not more than 2mm, its axis line and tape The vertical center line of the drum is no more than a fraction of the width, the horizontal roller shaft of not more than 0.3/1000.
b. If you find that tape to the side of the no-load total deviation should be adjusted idler bracket.
c. If you find no deviation tape at no load, and heavy load to the side of the deviation, indicating that the tape appeared partial load, coal hopper vent should be adjusted to the position.
3) strengthening routine maintenance:
a. timely removal conveyor rollers, roller, splice at other major parts of the dust, and prevent the roller, roller-stained dust lead belt run.
b. timely adjustment of tape running deviation phenomenon occurs, promptly check the tape edges and joints wear, identify problems and timely replacement and repair.
4) Install belt run the monitoring device, once the belt run off the alarm signal to alert maintenance personnel to take action.
2.3 Tear accident prevention
A) timely repair worn funnel, avoiding direct coal gangue and pound the tape.
2) the timely processing of deviation fault, not tear tape.
3) Set the tape longitudinal tear monitoring devices, found fault timely manner.

Troubleshooting belt conveyor

To address such failures is important to note the dimensional accuracy of installation and daily maintenance. There are several reasons for deviation, to be based on the difference between handling different reasons.
1 Adjust the belt conveyor idlers bearing Belt Conveyor in the middle of the entire belt conveyor idlers deviation, adjust the position to adjust the deviation; idlers in the manufacture of both sides of the mounting holes are worked into holes for be adjusted. Specific adjustment method, the specific method is biased which side of the belt, idlers which side of the belt toward the forward direction forward, backward, or the other side. Figure 1 shows the direction of the belt upward deviation is lower roller group should be located at the left, the upper roller group moved to the right place.
2 Install aligning roller group aligning roller group has many types such as an intermediate shaft type, four-link, vertical roller type, etc. The principle is the use of block or roller rotates in the direction in the horizontal plane lateral thrust block or generate the Automatic belt adjustment belt deviation reaches to the heart of the purpose. Average total length of the belt conveyor or belt conveyor shorter run time using this method bidirectional more reasonable, because the shorter belt conveyors easier deviation and not easy to adjust. And long belt conveyor is best not to use this method, because self-aligning roller group life belt use would have some impact.
3 Adjust the drive pulley and the driven pulley and bend pulley position adjustment bend pulley belt deviation adjustment is an important part. Because a belt conveyor with at least two to five rollers, all the rollers must be perpendicular to the installation location of the longitudinal direction of the belt conveyor centerline, if the skew is too large deviation inevitable. Adjustment Method and its group of similar idlers. For the head drum as the drum belt deviation to the right, the right of the bearing should be moved forward, the belt deviation to the left of the drum, the left bearing housing should be moved forward, also the corresponding After moving the left or right side bearing housings after the shift. Rear roller adjustment method and the head drum opposite. Adjustment method. After repeated adjustments until the belt transferred to an ideal location. Adjust the drive or bend pulley in the best pre-install its exact location.
4 tension belt tension adjustment at the adjustment at the conveyor belt deviation adjustment a very important part. Hammer at the upper two tensioning idler pulley in addition to other than perpendicular to the longitudinal direction of the belt should be perpendicular to the vertical line of gravity, which is to ensure its axis horizontal centerline. Tensioning screw or hydraulic cylinders with tension, the tension of the two roller bearing shall simultaneously pan, to ensure the longitudinal direction of the drum axis and perpendicular to the belt. Specific method of adjusting the belt deviation adjustment of the drum at similar.
5 reprinted point blanking position on the belt deviation of reproduced material blanking at the point position on the belt deviation has a very big impact, especially in the two belt conveyor in the horizontal plane perpendicular to the projection of a greater impact. Usually reproduced points should be considered down two belt conveyor relative height. The relative height of the lower horizontal velocity component of the material the greater the impact on the lower side of the belt is greater, while the material is difficult to center. The cross section of the material on the belt deflection, resulting belt deviation. If the material is biased to the right, then the belt deviation to the left, and vice versa. In the design process should be possible to increase the relative height of two belt conveyor. In space-constrained mobile bulk material handling machinery down funnel, guide trough and other pieces of form and size should be seriously considered. General guidance for the width of the trough belt width should be about two-thirds more appropriate. In order to reduce or avoid the belt deviation increase blocking plate blocking materials, changing direction and position of the whereabouts of the material.
6-way running conveyor belt deviation adjustment bidirectional running belt conveyor belt deviation adjustment than the one-way conveyor belt deviation relative to the adjustment much more difficult, specific adjustments should be adjusted in a certain direction, and then adjust another direction. Adjust the belt to carefully observe the movement direction of the relationship with the deviation trend, individually adjusted. Emphasis should be placed on the drive pulley and bend pulley adjustments, followed by the adjustment of the roller and the material blanking point adjustment. Also note that the belt when the belt curing joint cross the longitudinal direction of the force evenly in the use of both sides of the chain traction force equal as possible.

The working principle and structure of belt conveyor

Belt Conveyor is used as traction mechanism and bearing a continuous transport machinery sector, which is the main transportation equipment of bulk materials, with continuous operation, transport capacity, running resistance, low power consumption, smooth operation, transport en route to the materials in the crushing of small, easy to realize automatic control, etc., are widely used in coal, metallurgy, port transportation, building materials and other departments. With the development of national economy and scientific and technological progress, belt conveyor applications will become increasingly widespread.
Conveyor works as follows: The head belt around the drive pulley and tail redirecting roller Jane endless belt to form a non-polar, while the upper and lower belts were supported on the upper and lower rollers, the tensioning device In normal operation to the desired belt tension. When the drive unit driven by the drive roller rotates with the drive roller and the friction between the belt and the conveyor belt running along the above goods, goods are carried on a conveyor belt to the nose, due to steering belt is achieved Uninstall.
The fuselage cross-section belt. Cargo transported on conveyor belts, conveyor belts called this part of the working section or heavy segment; under the conveyor belt transporting goods is not known as an empty segment.
Can be used for horizontal and inclined belt conveyor transport. Typically, the transportation of coal along the inclined, the angle is not greater than 180, is not greater than 150 downward transport, transporting drilling significant adhesion and large materials, inclination can be appropriately increased.
Belt disadvantages are: conveyor higher cost and easy damage, should not be hard, angular materials transportation; compared with other devices, higher initial investment, but can not be used too much inclination occasion.
Many types of belt conveyors, scope and characteristics of each are not identical. The main types are: common type conveyor, belt conveyor frame hanging rope, retractable belt conveyors, powerful conveyor, wire rope conveyor, belt conveyor intermediate multi-stage driver and large cushion belt conveyor and so on.
With the rapid development of China's coal industry, mine traffic increasing, in a large pit on the main level and sloping roadway, using a large volume, long-distance belt conveyor is extremely beneficial, steel cord conveyor belt is to adapt kinds of needs and design a powerful belt conveyor. It is the common type of belt conveyor difference is that it uses steel cord conveyor belt instead of the ordinary, its tensile strength than the ordinary type increased IL times, even in recent times, greatly improved conveyor transmission capacity.

Dynamic analysis of belt conveyor main problem to be solved

Belt Conveyor dynamic analysis of the most important feature is the change in the previous study each component individually designed patterns to various components of the conveyor the best way to work together for the ultimate goal, the conveyor as an organic whole to conduct a comprehensive analysis, find the optimal combination of model and control strategy in the economic, reliable conditions, to improve the overall performance of the conveyor.
Dynamic analysis in modern belt conveyor design to solve the main problem between the following aspects:
(1) Calculate the transport conveyor driven in operation of the peak value and the tension condition occurs. Conveyor drive tension peak is generally several times its normal operating tension or even ten times, and according to the way the previous static design tension value calculated is much smaller than the actual value, we can only increase the safety factor to ensure delivery safe operation of the machine. In the absence of reliable analytical tool in the case, the use of empirical methods to determine the factor of safety is often made too large, it will inevitably result in increased costs, waste of investment.
(2) analysis of the vibration conveyor belt running it special law. Vibration is causing tension increase was mainly driven conveyor, belt accident is caused by the culprit, find out the rules for the effective control of its dynamic tension the belt of great significance.
(3) study the boundary conditions on the conveyor belt vibration regulation impact. Boundary conditions conveyor belt means all affect the dynamic characteristics of internal conditions and external conditions, such as driving, tensioning devices, roller, load and so on. To analyze the changes of these boundary conditions on the vibration impact and vibration conveyor find optimal hop's best special form of the boundary conditions.
(4) the boundary conditions optimized working conveyor through dynamic analysis to determine the best configuration for transport subsystem.
(5) based on comprehensive analysis of the results of the evaluation, selection and reasonable belt conveyor structure and configuration, so that in performance and comprehensive economic indicators optimal.

Belt conveyor is probably how correct standard operating

In industrial production , often because the operation is not standardized , resulting in a number of security incidents site today tell us about the safe operation of the conveyor belt , cuts in production safety hazard.

First and foremost, before the open belt conveyors , belt conveyors to recognize in a normal situation , the various components are not damaged , circuit, gas supply voltages are in the preparatory position open belt conveyors caliber power .
After an open Belt Conveyor , it is necessary to follow strict rules by the line of operations:

1 Close the total power , look at all the hours of operation the power light conditions, see the end , admit and correct and then the following operations

(2) The second step of each loop is closed by one power switch, view the LEDs and the belt conveyor is not a unusual. Under normal circumstances are: inverter and other equipment power indicator light, the inverter panel show normal appearance ( no fault code appears ) , belt conveyor operation indicator is not lit , the device does not operate.

3 By launching the process in accordance with electrical equipment , electrical equipment launched on a normal ( motor or other equipment has reached the normal speed , normal conditions ) and then the next one to launch electrical equipment .

In the belt conveyor operation, it is necessary to abide by the items are shipped items depicted in the rules and abide by the ability to depict the belt conveyor . Secondly, we must pay attention to all categories of personnel not touch the belt conveyor movement somewhat , non-professionals are not free to touch electrical components , control buttons, etc. . Eventually, the belt conveyor operation of the inverter can not break after the class , if it decides that needs repair , it is necessary in the case of suspension frequency operation carried competence , or can damage the drive .

Belt Conveyor
