斯卡利露天矿生产的矿石经两台137cm×188cm旋回破碎机中的一台破碎至—20.3cm后,由胶带输送机运往粗矿仓贮存。一台自动化的矿石转载输送机将粗碎矿石分配到6个矿仓。粗矿仓的有效容量共计为15000t左右,即一个班的矿石产量。用一套激光系统测量各矿仓的料位。矿仓内的矿石经6台122cm宽的胶带输送机送至选矿厂,每部输送机向1台7.3m、长2.4m的自磨机供矿。自磨机的转速为11.5r/min,由总功率为1305kW的电动机驱动。自磨机将粗碎矿石磨至8目。筛分机的筛上产品返回自磨机,筛下产品进入粗选螺旋选矿机。2台破碎机的可利用率为86.2％,6台Dominion型自磨机的可利用率
The ore produced by the Scali open-pit mine is crushed to -20.3 cm by one of two 137 cm × 188 cm gyratory crushers and transported by the belt conveyor to the coarse ore storage. An automated ore transfer conveyor distributes the coarse ore to 6 mines. The effective capacity of crude ore warehouse totaled about 15000t, that is, a class of ore production. Measure the level of each silo with a laser system. The ore in the ore bin was sent to the concentrator via six 122cm wide belt conveyors, each of which supplied ore to a self-mill of 7.3m in length and 2.4m in length. Since the mill speed of 11.5r / min, by the total power of 1305kW motor drive. Mill from the mill coarse crushed ore to 8 mesh. Sieve sieve products returned from the mill, sieve products into the rougher spiral concentrator. The availability of 2 crushers was 86.2%, the availability of 6 Dominion mills
