Grinding disc and horizontal grinding machine

Abstract

The invention provides a grinding disc used in a horizontal grinding machine. The grinding disc is of a three-layer sandwich structure, a sandwich layer is a first manganese steel layer, two sides ofthe sandwich layer are provided with first composite layers, the side, close to the sandwich layer, of each first composite layer is provided with a first permanent magnet layer, the side, away from the sandwich layer, of each first composite layer is provided with a first rubber layer, and the surface field intensity of each first rubber layer is 10-30 mT. Two sides of the grinding disc are eachprovided with four arc-shaped stirring blades. Each stirring blade is of a three-layer sandwich structure, wherein a sandwich layer of the stirring blade is a second manganese steel layer, two sides of the second manganese steel layer are provided with second composite layers, the side, close to the second manganese steel layer, of each second composite layer is provided with a second permanent magnet layer, the side, away from the second manganese steel layer, of each second composite layer is provided with a second rubber layer, and the surface field intensity of each second rubber layer is10-30 mT. Magnetite layers can be formed through the low field intensity, so that the grinding disc and the stirring blades are protected, and the service life of the horizontal grinding machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of ore grinding, and more specifically, relates to a grinding disc and a horizontal grinding machine for ore grinding. Background technique [0002] At present, my country's metallurgy, mining, ceramics and other industries have all set up grinding industries. Practical problems such as large investment, high power consumption, and large wear have been widely studied. [0003] At present, many ores, especially non-ferrous ores, have a particle size of 5-15 microns. When traditional horizontal grinding equipment such as ball mills are in the grinding process, the rotation of the shell cylinder drives the rotation of the liner to lift the medium and materials. In order to achieve the grinding effect, but when the traditional grinding equipment such as ball mill is used for fine grinding, its energy consumption is high, and when the embedded particle size of the mineral is below 15 microns, the traditional grin...
