Ball Mill Liners DF009 Mill Liner Design And Installation With HRC50-55 Hardness a. Supply boltless liners for coal-fired power plants, cement works and mines. b. Supply qualified custom-made mill liners Ball Mill LinersDescription: A. Martensitic Cr-Mo Alloy SteelMill Liners With our special double-media quenching process, the liners canachieve the following features: 1. Ideal hardness: HRC50-55 2.Ideal toughness value: AK30~100J 3. Even hardness distribution: the hardness difference from surface to the core ofeach piece of liner castingis less than HRC1. 4. Better wear performance: Their anti-wear properties are 1.5 times as much as those of high manganese steel. B. High Cr White Iron Mill Liners 1. In wet process, based on specific working condition, we also would like to recommend 18Cr or Cr23 liners, which service life will be more than twice of high Mn Steel liners (13%Mn) in same working condition. 2. In cement mills, we recommend 12%Cr or 15%Cr 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.
