浮选机内的阻尼板,在生产过程中受到矿浆的强烈摩擦和腐蚀,每年不仅耗用大量钢材,而且还给制造、维修、管理带来了很大的工作量,检修周期不能延长,影响设备运转率的提高;由于设备的磨损,也不同程度地影响了分选效率。因此,这个问题很值得重视和解决。根据铸石具有耐磨耐腐蚀的特点,我们于1971年1月 Damping machine within the damping plate, in the production process by pulp strong friction and corrosion, each year not only consume a large amount of steel, but also to manufacturing, maintenance, management has brought a lot of workload, maintenance cycle can not be extended, the impact Equipment operation rate increase; due to equipment wear and tear, but also to varying degrees, the efficiency of the separation. Therefore, this issue deserves attention and solution. According to cast stone with wear and corrosion-resistant features, we in January 1971
