Walnut shell filter materials and walnut shell grinding materials

Walnut shell can be used as two main materials, filter materials and grinding materials.

• When walnut shell is used as filter materials, the walnut shell is mainly put into the walnut shell filter equipments, when the fluids go through the walnut shell filter from the equipment suction to discharge, the impurities are attached onto the walnut shells, achieving the filtering purpose. Walnut shell filter materials are mostly used in the oil filed, to remove the oil dirt of oily water. In the processing of walnut shell filter materials, it is simplier relatively. Just needing breaking up the walnut shells into small mesh sizes, and removing the other impurities from the walnut shells. Normally, the walnut shell filter materials are big mesh sized of 6# - 35#.
• When walnut shell is used as grinding materials, or abrasive materials, its processing is more complicated that it requires the surfaces must be smooth without any corner, otherwise the walnut shell will damage the surfaces of other objects when used as grinding materials. For example, when the walnut shell is put into spay gun as grinding materials to polish other objects, the walnut shell will damage the surfaces of other objects if the walnut shell has corners itself. And the grinding materials have wider range of mesh sizes, which include all of the mesh sizes from 4# to 200#.
