湿式自磨工艺是一种新的选矿工艺,其主体设备是湿式自磨机。衬板是自磨机在生产过程中的主要易损零件,其寿命的长短直接关系到磨机的作业率、材料消耗和检修工作量。由于我厂开始制造的第一批φ5.5×1.8米湿式自磨机衬板寿命很短,因而如何提高其衬板寿命,成为当时攻关试验的重要课题之一。为此,在一机部、冶金部组织的湿式自磨联合试验组和 Wet self-grinding process is a new beneficiation process, the main equipment is wet self-mill. Liner from the mill in the production process of the main vulnerable parts, the length of their life is directly related to the mill operating rate, material consumption and maintenance workload. As the first batch of φ5.5 × 1.8m wet self-abrasive linings started to be manufactured by our factory has a short life span, how to improve the service life of the linings has become one of the important topics of tackling tests at that time. To this end, in a machine department, the Ministry of Metallurgy organizations wet self-grinding joint test group and
