目前,我厂投产的七个系列一、二次球磨机,均采用Φ3.6×4M球磨机,它是生产工艺流程中的主体设备,其主要易损件是衬板。投产以来,我厂一直采用锰钢(ZGMn13)衬板,实践证明高锰钢衬板存在以下问题。 1.消耗优质高锰钢数量大。据统计,年均消耗量达一千一百多吨。每生产一吨铁精矿消耗0.61公斤。 2.成本高。根据投产以来成本平均计算,每生产一吨铁精矿,衬板消耗为0.90元。1983年消耗衬板一项就达一百六十多万元。
At present, the seven series of primary and secondary ball mills put into operation in our factory all adopt Φ3.6 × 4M ball mill, which is the main equipment in the production process. The main wearing parts are the lining boards. Since commissioning, our factory has been using manganese steel (ZGMn13) lining, high manganese steel lining has proved the following problems. 1. Consumption of high-quality high-manganese steel large number. According to statistics, the average annual consumption of more than 1,100 tons. Each ton of iron concentrate produced consumes 0.61 kg. High cost. According to the average cost of production since the operation, each producing one ton of iron ore concentrate, liner consumption of 0.90 yuan. In 1983, the consumption of liner reached more than 1.6 million yuan.
