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.
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.
The downstream trough is suitable for roughing and cleaning of ores with a particle size of 6–0mm.
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.
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.
Characteristics
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.
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.
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.
Structure
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).
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.
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).
