Therefore, sieving solid granular raw materials has become an inevitable process.

The existing sieving technology mainly adopts the method of passing the basket, just like the flour passing the basket at home: choose a suitable screen, tighten it on the basket frame with wooden strips, hold the basket and shake it. This method belongs to manual operation, the production efficiency is low, and the fine particles that are sieved are inconvenient to collect, and sometimes there is environmental pollution. Moreover, when selecting two sections of non-adjacent particles with a size within a specific range, four sieving treatments are required to complete.
