Magnetic lining plate of ball mill

Abstract

The invention discloses a magnetic lining plate of a ball mill, which is capable of increasing ore milling efficiency. The magnetic lining plate comprises a lining plate shell and magnetic pole groups, wherein the magnetic pole groups are connected to the lining plate shell; clamping openings matched with each other are respectively formed on two sides of the lining plate shell in a circumferential direction of a cylinder body, so that adjacent lining plates are limited by each other in a radial direction of the cylinder body; the magnetic pole groups are substantially arranged in the radial direction of the cylinder body according to a magnetizing direction; the magnetic pole groups are arranged in an axial direction of the cylinder body in a homopolar way; the magnetic pole groups are arranged in the circumferential direction of the cylinder body in such a way that N and S poles are alternate; a raised lifting strip is arranged on the working face of the lining plate shell; transverse magnetic pole groups are arranged between the lining plate shell in the position of the lifting strip and the magnetic pole group; the transverse magnetic pole groups are substantially arranged in the circumferential direction of the cylinder body according to the magnetizing direction; the transverse magnetic pole groups are arranged in the axial direction of the cylinder body in a homopolar way; and the transverse magnetic pole groups are arranged in the circumferential direction of the cylinder body in such a way that N and S poles are in circulation. The magnetic lining plate of the ball mill, disclosed by the invention, has the advantage of higher ore milling efficiency and is especially suitable for autogenous mills, semi-autogenous mills and one-section ball mills; and wear resistance of the magnetic lining plate is also kept.

Description

technical field [0001] The invention relates to a liner for a ball mill, in particular to a magnetic liner for a ball mill. Background technique [0002] Ball mills are widely used in metal and non-metal concentrators, cement plants, refractory materials, ceramics, electric power and other industries. They are key equipment in the mine grinding process. The most important working parts in the ball mill are the liner and the grinding medium. The impact and wear of the grinding medium and ore on the lining of the ball mill make the liner of the ball mill become one of the main consumption materials in the operation of the ball mill. Therefore, the quality of the liner and The quality of the performance directly affects the grinding quality and the service life of the ball mill. [0003] According to its working conditions, the ball mill is divided into: autogenous mill, semi-autogenous mill, one-stage ball mill and two-stage ball mill. The autogenous mill mainly refers to fe...

Problems solved by technology

Because the impact of the second-stage ball mill is small, the shell is relatively thin, and the requirements for wear resistance are not high. At present, there are cases where the second-stage small ball mill uses metal magnetic liners, but the autogenous mill, semi-autogenous mill, and one-stage The ball mill is subject to great impact, and the magnetic liner applied to the second-stage ball mill cannot be directly applied to the aforementioned ball mill

[0005] At present, there are also beneficial attempts to apply metal magnetic lining technology to a ball mill. For example, the Chinese patent document "New Ball Mill Magnetic Lining" published on March 10, 2010 with the announcement number CN101664708, but this kind of magnetic lining is only through Improving the performance of the magnetic pole group itself to increase the adsorption layer, and the surface of the lining plate does not have the lifting strip structure that the existing cast iron lining plate used for a ball mill usually has
