山东省规模为500(吨/日)以下的小型选矿厂的破碎流程有几种形式。由于流程的不同,及其在设备选型上的差异,产生了不同的技术和经济效果。探讨哪种流程既能在技术上满足工艺要求,又能获得较好的经济效果,对小型选矿厂破碎流程的设计和改造具有重要意义。本文以山东省某些小型选矿厂的生产实际为例进行比较说明。常见破碎流程(一)流程演变几种破碎流程如图所示。1.二段开路流程[图(a)]。香夼铅锌矿原设计采用这种流程,在生产中出现了下述问题。
There are several forms of crushing processes for small-scale concentrators in Shandong Province that have a size of less than 500 tons per day. Due to the different processes and their differences in equipment selection, different technical and economic effects have been produced. It is of great significance to discuss which kind of process can not only technically meet the technical requirements but also obtain better economic results, which is of great significance to the design and renovation of the crushing process of a small beneficiation plant. In this paper, some small-scale concentrator in Shandong Province, the actual production as an example to illustrate. Common crushing process (A) Process Evolution Several crushing process shown. 1. Two-stage open process [Figure (a)]. Xiangfan lead-zinc mine originally designed to adopt this process, the production appeared in the following questions.
