The equipment makes the material into the machine through the wind buoyancy effect,different sepcial gravity and diffrent granular material buoyancy,and the material and the same material size,shape,sepcific gravity separation;The thin flake materials with small specific gravity ,small particle size or large wind area absorbed by the wind are collected by the collector and dust collector and then dischargedf from the machine ,and the material with less wind force than the material of great importance and non-metal separation,power material,granular material,mixed material ,according to their specific gravity ,particle size or shape of different separation and separation;it is used in many industries such as mineral processing,chemical industry and waste reuse .
