选矿厂设计选矿厂设计趋向于设备大型化,但粗碎机例外,因为爆破技术的不断发展,使破碎机不是按处理量而是按最大矿块来确定其大小的必要性减少了。不论是用卡车从坑内,或是用前端式装矿机从矿堆把原矿直接给入自磨机,这种趋势都将继续下去。这种趋势的发展,将有可能最终取消粗碎及中碎。 Concentrator Design The design of the concentrator tends to be large in size, except for the crusher, which has reduced the need for the crusher to determine its size, not by throughput, but by maximum lump, due to the explosion. This trend will continue no matter whether the truck is used to plow ore directly from the mines into the pit or to use the front-end loader. This trend of development, it will be possible to eventually cancel the rough and broken.
