正压去石机是由位于机器底部的3个风机向上吹风，相当于把物料吹起来从而形

Stoner pressure at the bottom of the machine by blowing by the fan 3 upward, equivalent to blow up the material to form a layered material, the material in the above light weight materials below. <br>Heavy material near the bottom surface of the preparation of the mesh, a large friction force, so that the inclined surface is moved upward in the screen, flow out from the outlet end. Material upper / layer is small, moves down from the outlet to the low end.

The positive stone remover is an upward blow by three fans located at the bottom of the machine, which is equivalent to blowing the material up to form a material layer, with light material sits above and heavy material below.<br>The heavy material below is close to the preparation mesh screen, the friction is large, so that it moves upward on the tilted sieve surface and flows out of the high-end outlet. The material above/layer is small, moves downwards, and flows out of the low end exit.

The positive pressure stone remover is composed of three fans at the bottom of the machine to blow upward, which is equivalent to blowing up materials to form material stratification, with light materials at the top and heavy materials at the bottom.<br>The lower heavy material is close to the screen surface of the weaving mesh, so the friction force is large, so it moves upward on the inclined screen surface, and flows out from the high-end outlet. The material in the upper / layer is smaller, moving down and flowing out from the low-end outlet.<br>
