[0003] Existing technologies include the utility model with publication number CN202387593U, which discloses a cyclone for grinding and grading. The patent adopts a cyclone body, a feed pipe, an overflow pipe, and a grit nozzle. The cyclone body includes a cylindrical part and a conical part with a larger upper part and a smaller lower part. The top of the cylindrical part is detachably connected to the overflow pipe, and the bottom is detachably connected to the conical part. The bottom of the overflow pipe is inserted into the cylindrical part, and the grit nozzle is detachably connected to the bottom of the conical part. A feed pipe is fixed near the top of the cylindrical part, and the feed pipe is connected to the cylindrical part. The cylindrical part, the conical part, and the grit nozzle all include an inner wear-resistant material layer and an outer skeleton layer. This solves the problem that the screening efficiency is too low and it is difficult to implement effectively in industry.
