负压去石机是在封闭的空间内向上抽风，相当于把物料向上提起来从而形成物料

Negative destoner is within the enclosed space in the exhaust, which is equivalent to an upward lift to the material to form a layered material is formed over a light material, the heavy material below. <br><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 lighter, moves downwardly, the outlet flow from the low end

Negative pressure de-stone machine is in a closed space to pump up, equivalent to lifting the material up to form a material layering, forming a light material above, heavy material in the lower.<br><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 light, moves downwards, and flows out of the low end exit

The negative pressure stone remover is to extract air in the closed space, which is equivalent to lifting up the materials to form material stratification, forming light materials on the top and heavy materials on 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 lighter, moving down and flowing out from the low-end outlet<br>
