1. adopt to roll roller and grid plate, can roll, break up the material of caking, the screen cloth screens the material granule once more, and the waste material of selecting is discharged from the waste pipe, and the material of selecting is difficult for blockking up pipe chain conveyer.

2. The arc-shaped surfaces can gather and contain more materials, so that the rolling of the rolling roller is facilitated; the outer circumference laminating of arcwall face and rolling pipe has increased area of contact, improves and rolls speed and work efficiency.

3. After the grinding roller grinds the materials, the brush can brush the materials adhered to the grid plate; the brush sets up on rolling the roller, can roll the material while, brushes the material of the adhesion on the grid board off, improves work efficiency.

4. The limiting groove and the limiting block limit the horizontal movement of the grating plate; the opening at the upper end of the limiting groove is opened, so that the grid plate can be conveniently taken out from the feeding pipe for replacement.
