high quality Walnut shell used as polishing material

Walnut shell 1uniform pores 2it is odorless, non-polluting, easy to use, 3 inexpensive and safe

Walnut shell filters material1  [pore-forming materials] walnut shell particlesOur factory using foreign advanced technology specialized in vitrified bond grinding wheel hole porosity materials - walnut shell grains. Compared with the old pore-forming material-- refined naphthalene, our product has uniform pores, and it is odorless, non-polluting, easy to use, inexpensive and safe. Moreover, the pore size of the grinding wheel can be arbitrarily selected. Thus, in 60 years abroad, it has been widely adopted in abrasives industry.
