Magnetic Liner

For the conventional ball mill liner, ore pulp and grinding media wear and impact the liner directly while in operation, along with the electrochemical corrosion at the same time.

or the conventional ball mill liner, ore pulp and grinding media wear and impact the liner directly while in operation, along with the electrochemical corrosion at the same time. But for the magnetic liner, the working principle is quite different: these magnetic liners are arranged alternately in the ball mill to form a strong magnetic field, the magnetic liner attracts a layer of broken or small steel balls and ferromagnetic minerals to the liner surface when in operation, thus forming a natural dynamic protective layer. In initial period, the workers can add broken balls or iron powder to help form the protective layer, which often can be 20~30mm. So the service life of the magnetic liner is extended greatly, is generally 10 times even dozens of times of high manganese steel liner.

Material:

Material and production process of the protective metal casing:

Our company’s researchers developed a special non-magnetic material, which consists of military special alloy metal and some necessary elements. This type material has many great properties:such as wear-resistant, acid-proof, Alkali-resistant,corrosion resistance and excellent non-magnetic permeability. All these properties enable the formation of sufficient strength and thickness of protective layer . By using EPC casting process, we produce metal casing with neat appearance and precise size, so the contact surface of the cylinder and magnetic liner can up to more than 95%.

Material of the magnetic

Based on years of experience, our company always use the the magnetic material with stable performance and reliable quality,this ensures high quality of our products, and in some vulnerable parts we add some NdFeB magnetic materials.

Material of the waterproof glue

Our company use imported waterproof glue, the strong adhesive makes the magnets and the protective layer firmly bonded together. And the good water resistance propertity makes the waterproof layer on the magnet surface have sufficient strength, not destroyed in the transportation, installation and use.

Features:

1.Long service life:

General can be used 4-6 years in the second and third stage for iron ore mining.

General can be used 2-4 years in the second and third of stage for Non-ferrous metal ore mining.

2.Light weight

The weight is 40-50% of manganese steel liner,so can reduce power consumption of the ball mill , which 7-10% lower than that of manganese steel liner.

3.Low consumption

Can reduce the grinding ball consumption for ball mill, 10% lower than that of manganese steel liner.

4.Damage prevention

Can make the ball mill does not leak ore, without wearing on bearing bush, non magnetic agglomeration.

5.Easy Installation

Installed in one day with less labor.

6.Optimal working environment

(1)Medium temperature 0-100℃ (2) Using Grinding ball ≤Ф60mm

7.Improve operation efficiency and increase throughput

Can make the ball mill grinding particle size finer than that of high manganese steel , and also can increase the capacity of the ball mill and mill operating rate increased by more than 1% .

8. Bring the enormous benefits

In the second and the third stage of ball mill using metal magnetic liner instead of high manganese steel liner, bring the enormous economic and social benefits to the enterprise.
