HRC58 Hardness Boltless Ball Mill Liners For Grinding Fine CaCO3 Powder Quick Details 1.Hardness: more than HRC58 2.Capacity increase 3.Size check: by steel templates 4.Internal quality check: by UT tester Boltless Mill Liners for Grinding Fine CaCO3 PowderDescription: In 1994, we designed the first super fine powder pulverizing ball mill production line and the boltless ball mill liners applicable to the super fine pulverizing field in China, which can achieve ideal output on the fineness of finished products with 2m90m. In 2.2 x 6m ball mill, the capacity is 3.2mt per hour on 2m10m, which has achieved leading level at home and abroad. In 2000, we designed the first set of the boltless liners applied in a super fine powder vibrating mill in China. In 2003, we designed and manufactured ball mill liners used in the largest super fine powder ball mills for Anhui Guofeng Nonmetal Hi-tech Material Co.(Jiuhua Calcium Co.) in China. Ball mill super fine powder pulverizing process mainly relies on liners. In the recent 20 years, our liners have been widely used in large, medium and small ball mills in Chinese power generation, mining, cement, Chemical engineering and metallurgical industries and super fine pulverizing equipments. It is the only recommended liner product in the latest standard of the electric-power industry in China. Technical Parameters Wuxi Orient Anti-wear Engineering Co., Ltd.
