Embodiment Construction

[0014] A new type of ball mill magnetic liner, such as figure 1 As shown, it includes a base 1 , a wear-resistant lining 3 , a composite magnetic pole set 2 and an adhesive 4 . A wear-resistant liner 3 is set on the inner wall of the base body 1. The wear-resistant liner 3 is made of high-strength and high-wear-resistant cast steel to protect the magnetic pole group. The percentage content of each component in the wear-resistant liner 3 is: C: 0.7%~0.9%, Mn: 14%~16%, Cr: 3.95%~4.05%, Si≤1.0%, S≤0.03%, P≤0.06%, and the rest is Fe. There is a cavity inside the wear-resistant lining plate 3, and the composite magnetic pole group 2 is bonded in the cavity of the wear-resistant lining plate 3 through an adhesive 4. Good shock absorption performance, etc., can effectively deal with extreme industrial and mining, and protect the magnetic pole group from oxidation. The high elastic performance of the adhesive 4 also reduces the impact and vibration of the material and grinding medium...

Abstract

The invention relates to a novel magnetic linger plate of a ball mill, comprising: a substrate, a wear-resistant linger plate, composite magnetic pole groups and a binding material. The wear-resistantlinger plate is arranged on the inner wall of the substrate, a hollow cavity is arranged in the wear-resistant linger plate, the composite magnetic pole groups are bound in the hollow cavity of the wear-resistant linger plate by the binding material, the composite magnetic pole groups are arrayed in same polarity along the axial direction of a ball mill cylinder and alternatively arrayed in N-pole and S-pole along the circumferential direction of the ball mill cylinder, the wear-resistant linger plate is cast by special ZG80Mn15Cr4, the composite magnetic pole groups are formed by high-performance ferrite materials and high-performance alloy magnet steel, the binding material is made from a novel material of America Fushilan. The novel magnetic linger plate has the advantages of rationally structural design, relatively high magnetic field strength and long service life; therefore, the novel magnetic linger plate can be widely used in ball mills.

Description

technical field [0001] The invention relates to an anti-wear device, in particular to a novel magnetic liner for a ball mill. Background technique [0002] The ball mill is the key equipment of the mineral processing project, and the magnetic liner is also the core component of the ball mill, and its consumption accounts for about 5% of the total cost of the mineral processing. Judging from the current usage of magnetic linings, the average cost of using them is only 38% of that of high manganese steel linings. And the mill can save energy by more than 30%. Due to the equipment material, structure and magnetic field structure, ball mills are not widely used in the field of mineral processing, especially in the first stage of grinding with a ball diameter greater than 100mm, and most of the fields with poor working environment. Although the magnetic liner has been applied, its service life is only about one year, and the economic effect is not obvious. Contents of the inv...
