杨家杖子矿务局选矿厂的职工将φ3.2m×3.1m格子型球磨机进行了改造,筒体接长了1,100毫米,提高了球磨机的处理能力,同时也有助于细磨矿。原电机是苏制DC213/2。一14型(瓦千),600,定子电流140安。改装前曾对电机容量进行了近似验算,要过载5.1%,考虑在运转中可通过装球量和给矿量来调整。改装前曾在原球磨机中增加内衬13.68吨、钢球15吨加
Workers Yangzizhangzi Mining Bureau dressing plant will be φ3.2m × 3.1m lattice ball mill has been transformed, the barrel then 1,100 mm long, improving the processing capacity of the ball mill, but also contribute to the fine grinding. The original motor is the Soviet system DC213 / 2. A type 14 (watts thousand), 600, the stator current 140A. Before the modification of the motor capacity was approximately checked, to be overloaded 5.1%, consider the operation can be loaded by the ball and to adjust the amount of ore. Modified before the original ball mill to increase lining 13.68 tons, 15 tons of steel plus
