本文的目的是探讨大型细碎车间的各种设计方案,并在研究了设计任务和条件的基础上进行了可供参考的各项方案设计。在工业实践中通常是将坑内或露天矿送来的矿石先采用三段破碎后再行进一步加工处理。第一段破碎即粗碎一般是在颚式破碎机或旋回破碎机中进行,其产品粒度一般为6″～10″即作为细碎的给料。 The purpose of this paper is to explore various design schemes for large crushing plant and to design various schemes for reference on the basis of studying the design tasks and conditions. In industrial practice, the ore that is usually sent from a pit or an open pit mine is first crushed and then further processed. The first paragraph of the crushing or coarse crushing is generally carried out in the jaw crusher or gyratory crusher, the particle size of their products is generally 6 “~ 10” as a fine feed.
