Problems solved by technology

[0003] This shows that above-mentioned existing ball mill liner obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved
In order to solve the problems of lining boards, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable material for general products to solve the above problems. This is obviously a problem. Issues that relevant industry players are eager to solve

Embodiment 1

[0043] figure 1 It is a structural schematic diagram of Embodiment 1 of the ball mill composite liner of the present invention. Such as figure 1 As shown, the composite liner of the ball mill includes a plate body with mounting holes 3 on the plate body. The plate body includes a metal bottom layer 1 cast from scrap steel and an ultra-high molecular weight plastic layer 2 pressed on the metal bottom layer. The thickness of the metal bottom layer is about one-third of the total thickness, which can optimize the wear resistance, overall strength and cost of the ball mill composite liner of the present invention. The composite liner of the ball mill in this embodiment is a flat liner, the upper surface of which is composed of a front plane and a rear slope. Wherein the ultra-high molecular weight plastic layer 2 is preferably an ultra-high molecular weight ultra-high structural plastic. The ultra-high molecular weight ultra-high structural plastics are selected from the ultra...

Embodiment 2

[0045] figure 2 It is a structural schematic diagram of Embodiment 2 of the ball mill composite liner of the present invention. The difference from Example 1 is that the composite liner of the ball mill is a stepped liner, and the side of the liner is trapezoidal. The assembled liner is stepped in the ball mill, which can increase the grinding of materials by steel balls.

Embodiment 3

[0047] image 3 It is a structural schematic diagram of Embodiment 3 of the ball mill composite liner of the present invention. The difference from Example 1 is that the composite liner of the ball mill is a corrugated liner, that is, the upper surface of the composite liner of the ball mill has alternate concave and convex stripes in a corrugated shape. It can increase the grinding of materials by steel balls.

Abstract

The invention discloses a composite liner for a ball mill and a manufacturing method thereof. The composite liner for a ball mill comprises a plate body with installation holes, and the plate body includes a metal bottom layer and a plastic layer compounded on the metal bottom layer. The manufacturing method of the composite liner of the ball mill comprises the following steps: a. preparing a metal bottom layer; b. compounding a plastic layer on the metal bottom layer; and c. cooling to complete. The composite lining plate of the ball mill of the invention has the advantages of high strength, good wear resistance, and not easy to break and crack.

Description

technical field [0001] The invention relates to the technical field of lining plates used in machinery manufacturing industry, in particular to a composite lining plate of a ball mill and a manufacturing method thereof. Background technique [0002] The liner is a commonly used equipment in the machinery manufacturing industry and is in great demand. At present, manganese steel linings, high alloy linings, magnetic linings, rubber linings, medium carbon and medium chromium linings are mostly used in the industry. Especially in the mining industry, due to the strong impact of the work on the liner, the magnetic liner can only be used in the second stage of the beneficiation process, and the rest, such as ball mills, need to use high manganese steel liners. High manganese steel liners have good toughness, but poor wear resistance. Such as high-alloy liners, rubber liners, medium-carbon and medium-chrome liners, etc., or due to poor strength or poor wear resistance and other ...
