Stone removal machine is an indispensable equipment for removing impurities in Flour mill. It is mainly used to remove the side stones mixed in wheat seeds to reduce the sand content of flour and ensure the quality of flour. If we know the working principle and operation of the stoner and do not know why, it is undoubtedly not conducive to improving the process effect of the stoner. In addition to the need for this equipment in flour mills, stone removal equipment can also be used to separate impurities such as shoulder stone from rice and wheat that are larger than grain, and can also be used to separate heavy impurities in some other grains.

The main working process of this type of grain stone removal equipment: when the material enters the stone removal equipment, due to the difference in the suspension speed of the stone and wheat, under the joint action of the appropriate vibration and updraft, the wheat with the smaller suspension speed floats on the upper layer, and the stone with the larger suspension speed sinks into the bottom close to the equipment, forming an automatic classification phenomenon. At the same time, due to the action of air flow, the porosity between the materials increases, and the positive pressure and friction between the material layers decrease.

In foreign countries, a new type of stone removal machine developed on the basis of similar products adopts suction primary and blow check structure. There will be a part of grain in the stones discharged after primary, and the mixture of this part of grain and stones will be checked again. The check screen surface is equipped with a built-in fan to blow air, so that the stone and grain are completely separated, and the stone is discharged from the stone discharge port after concentration.
