Gravity grading stone destoner commonly used in flour mills
Gravity grading stone destoner is a kind of cleaning equipment commonly used in flour mills. It is a kind of equipment with both grading and de-stone functions. It is widely used at present.
The main working mechanism of the gravity grading destoner is a parallel screen surface of the two-layer device in the same sieve body.
The upper sieve surface is a grading sieve surface, and the wheat can be divided into heavy particles and light particles according to the size of the suspension speed, and the grading screen surface is composed of a pre-sorting section and a diversion section.
The material first enters the pre-segmentation section. Under the action of vibration and updraft, the material is graded and then flows into the diversion section. The splitter screen has a large mesh opening, so that the heavy particles including all the shoulder stones fall into the second sieve surface.
The second layer is the stone-removing surface, which undertakes the falling heavy particles and completes the stone removal by the action of vibration and air flow.
