Special mineral magnetic separator conveying belt composite material and manufacturing method thereof

Abstract

The present invention discloses a special mineral magnetic separator conveying belt composite material and a manufacturing method thereof. The special mineral magnetic separator conveying belt composite material comprises an upper surface layer, a lower surface layer and a sandwich layer, wherein the upper surface layer is a polytetrafluoroethylene layer, the lower surface layer is a rubber layer, the sandwich layer is an aramid fiber layer, and the aramid fiber layer is a mesh structure woven from a lot of aramid fibers according to a certain order. According to the present invention, the composite material is formed by compounding three materials, and has characteristics of high strength and high toughness; the upper surface layer has characteristics of low friction coefficient, wear resistance, acid resistance, and alkali resistance; the lower surface layer material is anti-slip; the whole thickness of the composite material is ultra-thin so as ensure the magnetic permeability of the mineral magnetic separator; the cross section can resist 18 ton pull force, and the tensile strength is 6 times the tensile strength of the ordinary steel wire; and the upper surface layer is smooth, the sliding friction coefficient 0.01 ensures that the impurity can not attach on the conveying belt surface, the anti-fatigue strength is 120, and the flexibility is good.

Description

technical field [0001] The invention belongs to mineral processing equipment, and relates to a special conveyor belt composite material for mineral magnetic separators and a manufacturing method thereof. Background technique [0002] The development of beneficiation equipment and beneficiation process is synchronous. The traditional beneficiation process adopts chemical beneficiation method, generally adopts chemical precipitation method, metal exchange method, reduction precipitation method, electrowinning method and physical beneficiation method to precipitate from leachate or purification solution. Precipitation of chemical concentrates. However, our country is prolific in lean ore with low mineral content. Using chemical beneficiation method for ore dressing has high cost and low output, which will bring pollution to the environment. Currently existing mineral processing equipment such as centrifugal separators, chute separators and magnetic separators. Centrifugal con...

AI Technical Summary

Problems solved by technology

The outer surface of the conveyor belt on the mineral magnetic separator has been in contact with the pulp for a long time, and the surface is severely worn, and the surface of the ordinary cotton canvas conveyor belt and nylon conveyor belt is rough and difficult for the pulp to flow.

Therefore, the service life is short and cannot be applied to the conveying system of the mineral magnetic separator

The increase in thickness will lead to a decrease in relative magnetic permeability, which will affect mineral screening.

[0003] There is a lack of a material with high strength and toughness, low friction coefficient on the upper surface, and acid and alkali resistance; the material on the lower surface is non-slip, and the thickness of the material should be as thin as possible to ensure the magnetic permeability of the mineral magnetic separator.
