前言在选矿厂设计中,矿浆自流坡度的决定颇为重要,因考虑到为节省常年的动力费用,要使全厂的主要矿流保证重力运输。如果坡度太小,矿液达不到自流的目的,使生产发生困难;若坡度过大,又增大有关设备的配置高差,提高厂房建筑造价,并使返回矿液增大输送动力消耗。因此,正确选择流槽和自流管的坡度是很重要的。如何才能使流槽和自流管坡度选择得合理,目前还没有很好的方法,因各选厂处理的原矿性质不同,自流坡度也有所不同。在
Preface In the design of the ore dressing plant, the decision of gravity gradient of slurry is of great importance. Considering that in order to save perennial power costs, it is necessary to ensure that the main ore flow in the entire plant will be transported by gravity. If the slope is too small, the mineral water can not reach the goal of gravity flow, making the production difficult. If the gradient is too large, the height difference of the equipment will be increased, the cost of the plant will be raised, and the return fluid will increase the transmission power consumption. Therefore, it is important to properly select the slope of runner and gravity pipe. How to make the runner and gravity pipe slope to choose a reasonable, there is no good method, due to the various processing plant ore of different nature, gravity slope is also different. in
