1、 Explanation

The HCG type dry pre selection machine is mainly designed for pre selection of 5% -20% ultra-low grade, low-grade magnetite and dry powder ores, effectively improving the grinding grade, reducing the beneficiation cost, and improving production efficiency.

3、 Main technical parameters

◇ Good beneficiation effect:

Unique magnetic system design effectively controls tailings while improving concentrate grade, achieving good beneficiation effect;

◇ Large processing capacity:

By using a frequency converter to control the working speed, it is possible to achieve 1.5 times the processing capacity of equipment of the same specifications;

◇ Wear resistance:

The cylinder watch is made of wear-resistant ceramics with a hardness of HRA ≥ 85, which can reach HRA92 or higher, and has superior performance that cannot be replaced by other wear-resistant metal materials;

◇ Wide application range:

The unique material separation structure design can flexibly control the grade of fine and tailings, and can be widely used for pre enrichment of 0-12mm powder ore;

4、 Principle

By utilizing the principle that magnetic substances can be attracted by permanent magnets, a semi-circular magnetic system is designed inside the drum through which the material flows to form a larger magnetic field. When the material flows through this magnetic field area, the magnetic ore is immediately captured by a strong magnetic force and adsorbed on the drum adsorption surface of the semi-circular magnetic system. When the magnetic ore is brought to the non-magnetic area in the lower part, it falls to the concentrate outlet under its own weight and is discharged. Non magnetic ores or ores with lower iron grades can freely flow through the magnetic field to the tailings outlet under the action of gravity for removal.
