我厂选矿车间φ900mm×1500mm球磨机,自建厂以来一直使用高锰钢筒体衬板,高锰钢衬板价格高,耐磨性能差,噪音大,不易密封,并且装拆也十分不便。针对上述问题,我厂和赣县橡胶厂于1989年初联合研制耐磨橡胶衬板,同年5月底试制完成。6月初安装在该球磨机上试用。运行至1990年6月,累计2533小时。共处理硫化矿438t,萤石矿300t。φ900×1500mm球磨机转速34r/min,装高铬钢球1200kg,钢球配比为φ60mm:φ50mm=43:57。人球磨机的物料是含钨、钼、铋、铜等金属的硫化矿,还含有氰化钾、硫酸锌等腐蚀性物质。给矿粒度—2mm,湿式磨矿。两种衬板使用效果见下表。
I plant dressing workshop φ900mm × 1500mm ball mill, since the construction has been using high manganese steel cylinder liner, high manganese steel liner prices high, poor wear resistance, noise, easy to seal, and the installation is also very inconvenient. In response to the above problems, our factory and Ganxian rubber factory jointly developed wearable rubber lining in early 1989, and the trial production was completed by the end of May of the same year. In early June installed on the ball mill trial. Operation until June 1990, a total of 2533 hours. A total of 438t sulfide ore, fluorite ore 300t. φ900 × 1500mm ball mill speed 34r / min, equipped with high-chromium steel ball 1200kg, steel ball ratio is φ60mm: φ50mm = 43:57. Human ball mill material is tungsten, molybdenum, bismuth, copper and other metal sulfide ore, also contains potassium cyanide, zinc sulfate and other corrosive substances. To the mine size -2mm, wet grinding. The effect of the two liner see table below.
