Compared with the prior art, the utility model discloses the beneficial effect who possesses is:

1. the utility model discloses directly set up the feed inlet at shell low side top, can effectively fully promote the raw materials to the rubbing crusher of next process in, compared with the prior art put into silo, by the feeding of spiral elevator bottom opening with spiral elevator low side, the material that can not be promoted has relatively reduced a lot (namely remains in the silo or spiral elevator bottom and not promoted the raw materials to the rubbing crusher and reduces a lot relatively);

2. the utility model screens the raw materials for large impurities before entering the spiral elevator, which can effectively prevent the large impurities from entering the spiral elevator and then entering the crusher;

3. the utility model is provided with a second impurity outlet at the bottom of the lower end of the shell of the spiral elevator, and is fixedly connected with the filter screen at the position of the outlet, so that part of fine sand or fine soil can be filtered;

4. the utility model discloses set up the filtration pore on the helical blade, can select tiny impurity at the in-process that promotes to the raw materials to improve the quality of final product.
