本文叙述乌拉尔石棉联合企业处理含石棉2%的低品位矿石,年处理能力为1800吨。矿石准备在破碎筛分车间完成,粗碎和中碎采用圆锥破碎机,细碎采用锤式破碎机,筛分采用棒条筛和振动筛。干燥在垂直干燥器中进行。根据最终和给入物料的湿含量对干燥介质和给入矿石量进行自动控制,使矿石干燥稳定在有利于选矿的水平上。干燥后的矿石储存在落地式矿仓里,其用量为2～2.5天。多段破碎的目的是使有用成分分离,提取石棉精矿。因为影响精矿数、质量特征的因素很多,例如纤维化、纤维长度、粒级分析、在空气室中的空气速度、筛子处理量以及难筛硬颗粒的存在,都必须加以考虑,要根据具体情况的变
This article describes the Ural asbestos consortium dealing with 2% asbestos low-grade ore, the annual processing capacity of 1800 tons. Ore preparation is completed in the crushing and screening workshop, the crushing and crushing of the cone crusher, crushing hammer crusher, sieve using the rod screen and shaker. Drying is carried out in a vertical dryer. According to the final and the moisture content of the feedstock to the drying medium and the amount of ore fed to the automatic control, so that the ore is dry and stable in favor of beneficiation level. The dried ore is stored in a floor-standing silo in an amount of 2 to 2.5 days. The purpose of multistage crushing is to separate useful components and extract asbestos concentrate. Because there are a number of factors that affect the quality of the concentrate, such as fiberization, fiber length, fractional analysis, air velocity in the air chamber, throughput of the screen, and the presence of difficult hard particles, all have to be considered The situation changes
