Grain cleaning sieve wet and dry separation equipment

Ctgrain Grain Cleaning Machine is used to separate and foodstuff particle size, shape, similar and different weight of impurities, such as gravel, clay pieces, metal, glass and coal cinder, etc. Separation methods have wet process and dry process of two kinds:

Dry process equipment has specific weight and proportion of graded stone machines. Food in proportion to the stone machine being evenly feed into a porous plate tilt and reciprocating vibration (scales orifice plate or steel wire woven mesh), borrow a controllable flow and fluidization, borrow gravity flow to the bottom discharge to a state of suspension.

Typical equipment for washing wheat wet dryer, is made up of spiral water trough and vertical dry parts. Than the major impurities in the water tank precipitation speed, accumulation on the bottom of the channel by a screw conveyor to send to the discharge; Small wheat were large spiral conveyor float to dry parts, to remove the free to the surface of water. Heavy stones, such as soil, because of the reciprocating vibration on the perforated plate for top mobile, discharge by poly stone. Ways there are to provide air suction and blowing type two kinds. The proportion of the working principle and structure of the grading machine and proportion of stone machine is similar: food, together with the first impurity is divided into two parts according to the weight, then be cleared respectively, behind can reduce the number of cleaning equipment or to switch to smaller devices.
