The Experimental Research And Ash Feedback Control New-type Discharging Equipment In Jigging Machine

Discharging equipment is the important part of the jigger, the separation accuracy is not only having relation with whether raw coal can successfully separate by specific gravity, but also with having relation with the unloading way of the end product. If discharging is not appropriate ,it will result in the bed layer which is over thick or empty and make the layered material confusion, then it will weakened the separation effect. Therefore it is very magnificent for increasing the separation accuracy and productive capacity of the jig to improve discharging equipment of the jig .In the meantime , because jig is the major separation equipment in the washing plant which is used wildly and coving broadly , it will bring the big and economic performance with making any progress on the technique. Therefore, on the basis of studying theory the further developing on the practical technique and the equipments will be applied extensively.This thesis generalized the development process of the jigger and the basic theory of the jigger stratification and separation concisely . Making emphasizing on analysis and studying formation process of the bed layer inside the jig on the basis of density and size. especially distribution circumstance of the density and size in bed layer nearby discharging jaws of the jigger. Introducing the framework design and general ash feedback control scheme of the new kind Discharging equipment.
