hiddenValue
Details Introduction
This equipment is suitable for mining, coal preparation plants and other units. It is used for wet separation of fine-grained strong magnetic minerals under weak magnetic field conditions, or removal of mixed strong magnetic minerals from non-magnetic minerals.
本设备适用于矿山、选煤厂等单位,可在弱磁场条件下对细粒强磁性矿物进行湿式分选,或去除非磁性矿物中混入的强磁性矿物。
The machine has three types of tanks: semi-countercurrent tank (CTB), downstream tank (CTS) and upstream tank (CTN), which are respectively suitable for different mineral particle sizes and separation processes.
本机槽体分为三种类型:半逆流槽(CTB 型)、顺流槽(CTS 型)、逆流槽(CTN 型),分别适配不同的矿物粒度和分选工艺。
The downstream trough is suitable for roughing and cleaning of ores with a particle size of 6–0mm.
顺流槽适用于粒度为 6–0mm 矿石的粗选与精选作业。
The countercurrent trough is suitable for roughing and scavenging of ores with a particle size of 0.6–0mm, and can also be used for heavy medium recovery in coal preparation industry.
逆流槽适用于粒度为 0.6–0mm 矿石的粗选与扫选作业,同时可用于选煤行业的重介质回收工艺。
The semi-countercurrent trough is suitable for roughing and cleaning of ores with a particle size of 0.5–0mm, especially for cleaning of minerals with a particle size of 0.15–0mm.
半逆流槽适用于粒度为 0.5–0mm 矿石的粗选与精选作业,尤其适用于粒度为 0.15–0mm 矿物的精选作业。
Characteristics
设备特点The CTS series semi-countercurrent iron ore drum magnetic separator is usually used for sorting fine-grained magnetic minerals, or removing magnetic mineral impurities from non-magnetic minerals.CTS 系列半逆流铁矿石筒式磁选机通常用于细粒磁性矿物的分选,或从非磁性矿物中去除磁性矿物杂质。
Its composite magnetic system consists of high-performance rare earth permanent magnets (main magnetic source) and ferrite permanent magnets, with deep magnetic field penetration, which can realize continuous ore feeding and discharging.设备的复合磁系由高性能稀土永磁体(主磁源)和铁氧体永磁体组成,磁场作用深度大,可实现连续给矿与排矿。
The equipment has sufficient working clearance and high processing capacity. The content of non-magnetic substances in the separated concentrate is extremely low, and it can also be used for ore upgrading operations.设备具备充足的工作间隙和较高的处理量,分选后精矿中的非磁性物质含量极低,亦可用于矿石的提质作业。
Structure
设备结构
The CTB series magnetic separator is mainly composed of permanent magnetic pulley, trough, feed box, support frame, desilting system, cleaning system, discharge device, magnetic system adjustment mechanism and drive system (see Figure 1).CTB 系列磁选机主要由永磁滚筒、槽体、给矿箱、机架、排渣系统、清理系统、出料装置、磁系调节机构及驱动系统构成(见图 1)。

Working Principle
When the ore pulp enters the separation area of the wet drum magnetic separator, due to the difference in magnetic susceptibility of various minerals, the magnetic minerals will be adsorbed on the surface of the roller under the action of magnetic force, and will be brought to the concentrate discharge area with the rotation of the roller.当矿浆进入湿式筒式磁选机的分选区域时,由于各类矿物的磁化系数存在差异,在磁场力的作用下,磁性矿物会被吸附于滚筒表面,并随滚筒转动被带至精矿排料区。
After leaving the magnetic system, the minerals are washed into the concentrate box by flushing water. Weak magnetic minerals and non-magnetic minerals cannot be adsorbed, and finally flow into the tailings discharge pipe along with the ore pulp (see Figure 2).当矿物离开磁系作用范围后,由冲洗水将其冲入精矿箱。弱磁性矿物和非磁性矿物则无法被吸附,最终随矿浆流入尾矿排料管道(见图 2)。
