产品用途及特点
The magnetic separator produced by our factory is suitable for mining, coal preparation plants and other units, used for weak magnetic field wet separation of fine particles of strong magnetic minerals, or for removing mixed strong magnetic minerals in non-magnetic minerals, such as recovering magnetic heavy medium weighting agents in heavy medium beneficiation, concentrating low concentration slurry and magnetic minerals in iron beneficiation plants, processing the feed of the strong magnetic separator, removing magnetic or weak magnetic minerals and their associated bodies, and preventing magnetic medium blockage.
我厂生产的磁选机适用于矿山、选煤厂等单位，可用于强磁性矿物细颗粒的弱磁场湿法分选，也可用于去除非磁性矿物中混入的强磁性矿物，例如回收重介质选矿工艺中的磁性重介质加重剂、浓缩铁矿选矿厂的低浓度矿浆与磁性矿物、处理强磁选机入料、脱除磁性或弱磁性矿物及其连生体，同时可防止磁性介质堵塞设备。
The coarse-grained concentration magnetic separator is a specialized magnetic separator designed by our company for concentration. It is mainly used to increase the slurry concentration after primary grinding or when the coarse-grained slurry on the high-frequency screen enters the secondary grinding operation, in order to improve grinding efficiency and reduce production costs. The discharge concentration of this product can reach over 68%.
粗粒浓缩磁选机是我厂专为矿浆浓缩设计的一款专用磁选设备，主要用于一段磨矿后矿浆提浓，或高频筛上粗粒矿浆进入二段磨矿作业前的浓缩处理，以此提升磨矿效率、降低生产成本。该设备的排矿浓度可达 68% 以上。
The semi counter current trough type magnetic separator is suitable for wet coarse selection and selection of strong magnetic minerals with a particle size of 0.5-0 mm, especially for the selection of minerals with a particle size of 0.15-0mm.
半逆流槽式磁选机适用于粒度为 0.5-0mm 的强磁性矿物湿法粗选与精选作业，尤其适用于粒度在 0.15-0mm 区间内的矿物分选。
Introduction to the Main Component Structure
主要部件结构简介
The NCT type magnetic separator is mainly composed of permanent magnet drum, tank body, ore feeding box, bracket, dredging mechanism, filter press roller, cleaning mechanism, concentrate outlet, magnetic system adjustment device and power transmission device.
NCT 型磁选机主要由永磁滚筒、槽体、给矿箱、机架、疏通机构、压滤辊、清理机构、精矿排出口、磁系调节装置及动力传动装置组成。
Working Principle
工作原理
The magnetic package angle is 240 °, and the drum rotates in the opposite direction, which prolongs the time from the slurry leaving the liquid surface to unloading, and is conducive to the discharge of moisture;
磁包角为 240°，滚筒反向旋转，延长矿浆从脱离液面到卸载的时间，利于水分充分排出；
A floating filter press roller is installed at the upper part of the drum, which exerts a constant pressure on the mineral powder on the surface of the drum, squeezing out the moisture in the mineral powder;
滚筒上部安装浮动式压滤辊，对滚筒表面矿粉施加恒定压力，挤压出矿粉中所含水分；
Setting up a strong magnetic field zone at the bottom of the filter press roller allows the mineral powder to fully adsorb on the surface of the roller, which is beneficial for squeezing out moisture and avoiding the accumulation and return of mineral powder caused by the compression of the filter press roller;
压滤辊底部设置强磁场区域，使矿粉充分吸附于滚筒表面，既助力水分挤压排出，又能避免因压滤辊挤压导致矿粉堆积回流；
Reasonably design the drum speed, which does not affect the sorting effect and can effectively separate moisture and mineral powder;
滚筒转速经合理设计，在不影响分选效果的前提下，实现水分与矿粉的高效分离；
Use a scraper to unload the ore on the unloading side, without the need for unloading water.
卸载侧采用刮板卸矿方式，无需额外添加卸载水，简化作业流程。
