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出粮箱进入

Large impurities and small impurities are screened and discharged through the trash discharge pipe. The other better materials are screened out by the wind to the grain box and enter the specific gravity selection platform. The materials are stratified by the action of the wind, and the lighter materials (grate, mildew) In addition to the hopper discharge machine, the full material enters the screening classifier (optional), and the materials are divided into 3-5 grades (user requirements) according to the geometric size of the materials 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 through the wind screening grain box into the gravity selection platform, the material through the role of the wind layering, lighter materials (箅, mold) through the removal of the hybrid machine, full material into the screening grader (optional), according to the geometry of the material will be divided into 3-5 levels (user requirements) through the export of the tank.

Large impurities and small impurities are screened and discharged through the discharge pipe. The rest of the better materials are screened out of the grain tank by the air and enter the gravity concentration platform. The materials are layered by the effect of the air. The lighter materials (grates, moldy) pass through the discharge machine of the trash hopper, and the full materials enter the screening and grading machine (optional). The materials are divided into 3-5 grades according to the geometric size of the materials (user requirements) Each outlet of the discharge box is discharged out of the machine.<br>
