CGSL干式振动高梯度磁选机
CGSL Dry Vibratory High Gradient Magnetic Separator

一、概述

CGSL-1000干式振动高梯度磁选机是我国第一台连续运转、干法选矿的高梯度磁选机，适用于非金属矿物（高岭土、石英砂、长石等）的干法磁选除铁。它通过连续振动给矿、连续振动分选、连续振动排矿的方式进行非金属矿物的提纯。

干法磁选工艺是一种简单经济的加工工艺，非金属矿物经过干法磁选工艺不需要经过浓缩、脱水和干燥程序就能成为产品，可以大大节省投资和生产成本。

1. Introduction

CGSL-1000 Dry Vibratory High Gradient Magnetic Separator is the first continuously dry-processing high gradient magnetic separator in China . It is fit for removing iron from non-metallic ores like Kaolin, Quatz and Fluorspar with dry magnetic separation. It feeds, separates and discharges continuously with vibration for purifying non-metallic ores.

Technology of dry magnetic separation is a simple but economic processing method. Non-metallic ores can become products without procedures of concentration, dewater and dry. So, it saves up investment and production cost.

二、设备构造

干式磁选机要实现干法选矿,首先要解决的问题是干矿的流动问题。为解决这一难题，该设备采用的了振动给矿、连续振动分选、振动排出磁性物的全新思路，较为圆满地解决了这一难题。如图1所示，CGSL干式振动高梯度磁选机主要由转环、磁轭、激磁线圈、机架、转环振动电机，给矿斗振动电机、振动机构、轮胎联轴器、限位机构等组成。

2. Structure

CGSL-1000 Dry Vibratory High Gradient Magnetic Separator mainly consists of separating ring, magnetic yoke, energizing coils, support frame, vibrating frame, vibrating mechanism, ring-vibrating motor, tire coupling, feed system, concentrate box, position-limit mechanism and vibrating motor for feed as shown in Fig.1

三、工作原理

干矿进入给料系统后，在给矿斗振动电机的作用下，沿上磁轭缝隙进入分选区。转环支撑在振动机构的主振弹簧上，靠轮胎连轴器传递扭矩。在转环振动电机的作用下，转环一边振动，一边连续旋转。转环内装有磁介质盒，磁性矿被吸附在磁介质盒上，非磁性矿在转环振动力作用下穿过转环，进入非磁性矿斗排出机外。磁性矿随着转环转动脱离磁场，在转环振动力作用下脱离转环，被收集到磁性矿斗。磁性矿斗也随转环一起振动，从而将磁性矿排出机外。 整个分选和排矿过程都是在干式环境下进行的。矿粉的流动靠振动力实现。

3. Principle of Operation

Dry ore is fed into the separating zone along the slots of upper magnetic yoke under the force of vibrating motor for feed from feed system. Separating ring is mounted on the main vibrating spring of the vibrating mechanism and torque is transmitted by tire coupling. The ring rotates continuously and vibrates as well by the force of vibrating motor. The magnetic particles are captured by matrix, which are mounted on the ring, and non-magnetic particles just pass through the ring and enter into tail box being discharged from the machine under the force of vibrating ring. Magnetic particles drop into the concentrate box from the separating ring under the force of vibrating ring after they go far away from magnetic field with the ring rotation. And the concentrate box also vibrates with the ring to let magnetic particles flow out of the machine. The whole course of separation and discharge is done in dry circumstance. And minerals flow by vibrating force.
