Product Description
Walnut Shell
Walnut shell abrasive is a versatile media that is crushed carefully, ground and classified to standard mesh sizes for specific uses. They vary from abrasive grits to fine powders. Therefore, walnut shell abrasive have a wide variety of applications,especially in industrial areas, since they have unique physical characteristics and chemical properties. The Walnut Shell Grain can be used in cleaning and blasting Molds, Apparatus, Plastics, Gold and silver jewelry, Glasses, Watches, Golf Club, Barrette, Buttons etc as blasting materials, polishing materials and also can be used in producing Grinding Wheel as the materials of forming air hole.
Advantages of Walnut Shell
1. It has multi-faceted microporosity, strong interception power and high removal rate of oil and suspended solids.
2, with multi-ribbon and different particle size, forming deep bed filtration, enhanced oil removal capacity and filtration rate.
3, with hydrophobic oleophilic and suitable specific gravity, easy to wash back, strong regenerative power.
4, the hardness is large, and it is not easy to corrode by special treatment, no need to replace the filter material, only 10% per year, reducing maintenance and repair time and improving utilization. Walnut shell is a natural rolling material. It can not damage the surface of the workpiece and has good polishing effect.
