Silicon carbide grinding barrel is mainly used in the sand mill industry, machinery industry, mining industry, lithium battery industry, photovoltaic industry, paint, ink, food, cosmetic grinding and other mechanical grinding industries and as a high-wear mechanical bushing.

The two packing methods we use are plywood box packing and solid wood packing, with the solid wood box requires a fumigation certificate. Depending on the various products, we will tailor the proper packaging box; Plastic foam measuring 2 cm to 3 cm thick is placed within the box and secured with row nails. To maintain the products safety during shipment, packing tape is typically used.

The silicon carbide grinding barrel is a new type of ceramic product. Features of silicon carbide grinding barrel:

  • Lightweight and high-cost performance.
  • Good heat dissipation, the thermal conductivity of 130W/M.K (20°C)
  • High hardness, better impact resistance, erosion resistance and wear resistance than traditional wear-resistant ceramics such as alumina and zirconia.
  • The service life is 5 to 10 times that of general wear-resistant materials, the overall operating cost is low, and the cost performance is high.
