1972年末,在巴列依金矿的塔谢夫斯基选矿厂对 MMC-70-23型(φ7×2.3米)湿式自磨机进行了工业性试验。试验的目的是确定合理的工艺流程和最佳的操作参数。试验用的矿石为含金的石英—粘土质矿石。未安装自磨机前,运进选矿厂的矿石经过两段破碎。粘度为+35毫米—20%的破碎产品在球磨机中进行三段磨矿,然后在重浮选—氰化流程中进行选别。安装 MMC-70-23型自磨机后,取消了破碎工序。从矿山运来的粒度为-300毫米的矿石直接进入自磨机的矿仓。MMC-70-23型自磨
At the end of 1972, an industrial test was carried out on the MMC-70-23 (φ7 × 2.3 m) wet self-grinding mill at the Tatshevsky Concentrator at the Barrei gold mine. The purpose of the test is to determine a reasonable process and the best operating parameters. The test ore is gold-bearing quartz-clay ore. Not installed from the mill before, into the ore dressing plant after two broken. Crushed products with a viscosity of +35 mm - 20% are ground in a three-stage mill in a ball mill and are then sorted in a heavy flotation-cyanidation process. After installing MMC-70-23 self-mill, the crushing process was canceled. The ores with a particle size of -300 mm delivered from the mines directly enter the mills of the mill. MMC-70-23 self-grinding
