大杂质和小杂质经筛选后通过排杂管排出，其余较好的物料经风筛选后进入比重

Large impurities and small impurities are screened and discharged through the waste discharge pipe. The other better materials are screened by wind and then enter the specific gravity selection platform. The materials are stratified by the action of wind, and the lighter materials (grate, mildew) pass through the removal The hopper is discharged out of the machine, and the full material enters the screening classifier (optional). According to the geometric size of the material, the material is divided into 3-5 grades (user requirements) and discharged out of the machine through the respective outlets of the discharge box.

Large impurities and small impurities after screening through the drainage pipe discharge, the rest of the better material after wind screening into the gravity selection platform, material through the role of the wind layering, lighter materials (箅, mold) through the removal of hybrids, full material into the screening grader (optional), according to the geometry of the material will be divided into 3-5 grades (user requirements) through the discharge box each export machine.

Large impurities and small impurities are screened and discharged through the trash pipe. The rest of the better materials are screened by the air and then enter the specific gravity cleaning platform. The materials are layered by the effect of the air. The lighter materials (grates, moldy) are discharged through the trash hopper, and the full materials enter the screening classifier (optional). According to the geometric size of the materials, the materials are divided into 3-5 grades (user requirements) and discharged The outlet of each box is respectively discharged out of the machine.<br>
