The product, invented by Mr. Chen Chang- shun, senior engineer and the director of the company, is known as "China Best Liner". It includes two parts, high wear resistance boltless plates, and highly expandable riveting plates, which are self-fastened and strengthened to withstand impact from mill balls. With more than 20-year application in coal mills of power plants, ball mills of cement plants and mining mills, boltless lining system proves to be much more stable and reliable than traditional bolted lining system. The advantages of our boltless liners are no fastening holes, no leakage of powder, no breakage of bolts, no maintenance during working periods and noise reduction.
