Grain cleaning machine refers to the equipment used in cleaning, selecting and classifying. Different types of grain cleaning machine adopts different working principle to separate grain granules and impurities. The common grain cleaning machine can be divided into 6 types. Today, let’s talk about grain cleaning machine with granularity separation.

Grain cleaning machine with granularity separation adopts woven metal wire screen or punching metal plate as the screen. It can be classified into plansifter which has reciprocating vibration or flat revolving, and cylinder screen which has revolving rotation. According to the screen mesh and the grain granules size, we have the following two equipments:

First, the big screen or the drum sieve. Its mesh is a little larger than the largest diameter of the grain size. They can make the grains and the small impurities pass the mesh and the large impurities can be discharged as the oversize product.

Second, the rotary flat sieve and the high speed vibration screen with small mesh which is smaller than the smallest grain granules size. They can make the small impurities pass the mesh and remove them and the grains can be discharged as the oversize product. They are usually used in the cleaning process after the grains delivery from the storehouse and before processing.
