The fines exit the filter house 300 through the fines outlet 322 and then enter the fines fraction 200 for fine comminution. The coarse material exits the filtering portion 300 through the coarse material outlet 321, and is then conveyed to the pre-crushing portion 100 through the circulating portion 400 to be pre-crushed again.
Since the fine materials entering the fine crushing part 200 are filtered by the filter part 300, the size of the fine materials is within the specified range, the fine materials cannot cause obstacles to the rotary crushing of the second rotating part 210, and meanwhile, the products coming out of the fine crushing part 200 are ensured to be fine enough to meet the production requirements; the coarse material is recycled by the recycling part 400, and is guaranteed to enter the fine crushing part 200 only when reaching the specified size.
