金州石棉矿在选矿筛分流程中采用建材部第二非金属矿山设计院设计的锥筒筛,经过两年生产及单机实验,效果较好。锥筒筛的构造如图1。它主要由一个截头圆锥形回转筛筒1,其内装有较高速度反向旋转的筛轴2,轴上有呈放射状打击棒3,共四排,每排18～20个,沿整个筛轴长度上呈螺旋线安装,筛筒安装在筛体支承轴承4上,筛轴两端支承在左、右轴承5上。传动装置6是由一台2.2千瓦电动机通过三角皮带传动于筛轴和由一台1.6千瓦减速电机采用套筒滚子链传动筛筒而组成。筛筒外装有筛罩7,其筛罩上 Jinzhou asbestos ore in the screening process using the Ministry of Construction Non-metallic Mining Design Institute of Cone sieve, after two years of production and stand-alone experiment, the effect is better. Cone sieve structure shown in Figure 1. It consists of a truncated conical rotary screen cylinder 1, which contains a higher speed reverse rotation of the sieve shaft 2, the shaft has a radial strike bar 3, a total of four rows, each row 18 to 20, along the entire screen The shaft length was helical installation, sieve drum mounted on the sieve body bearing 4, the sieve shaft bearing on both ends of the left and right bearing 5. Transmission 6 is a 2.2 kilowatts motor through the V-belt drive on the sieve shaft and a 1.6-kilowatt gear motor using sleeve roller chain drive sieve drum and composition. Sieve cylinder equipped with a sieve cover 7, the sieve cover
