A ball milling device for cemented carbide rod production

Abstract

The invention relates to a ball milling device for producing cemented carbide rods, which comprises a base and a ball milling unit, and the ball milling unit is arranged on the upper surface of the base. The present invention can solve the existing problems: when the existing ball milling device wet-grinds the proportioned raw material powder, there is only one type of grinding ball in the ball milling device to grind the raw material powder through the cooperation with the inner wall of the grinding tank. Grinding and mixing, and this process is too simple, it is difficult to fully grind each component in the raw material powder to a certain particle size, so it is difficult to mix the components in the raw material powder more uniformly; due to the grinding method Too single, so the wet grinding processing time of raw material powder is too long, it is difficult to realize the purpose of discharging while feeding, resulting in low wet grinding processing efficiency of raw material powder, affecting the production efficiency of cemented carbide rods.

Description

technical field [0001] The invention relates to the field of making cemented carbide rods, in particular to a ball milling device for producing cemented carbide rods. Background technique [0002] Cemented carbide rods are hard alloy round rods, also known as tungsten steel rods. Cemented carbide is a composite material composed of refractory metal compounds (hard phase) and bonding metal (bonding phase) produced by powder metallurgy. Material; cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance, even at a temperature of 500 ° C, it basically maintains unchanged, it still has a high hardness at 1000 °C. Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass...

AI Technical Summary

Problems solved by technology

[0006] ①When the existing ball milling device wet-grinds the raw material powder after proportioning, there is only one type of grinding ball in the ball milling device to grind and mix the raw material powder through the cooperation with the inner wall of the grinding tank, and this process Too single, it is difficult to fully grind each component in the raw material powder to a certain particle size, so it is difficult to mix the components in the raw material powder more uniformly;

[0007] ②When the existing ball milling device wet-grinds the raw material powder after proportioning, because the grinding method is too single, the wet-grinding time for the raw material powder is too long, and it is difficult to realize the purpose of discharging while feeding, resulting in raw material The wet grinding processing efficiency of powder is low, which affects the production efficiency of cemented carbide rods
