Relationship between grinding process conditions and wear of grinding balls
Jun 28, 2019
Grinding process conditions and mill working conditions are also important system reasons that affect the wear, breakage and roundness of the grinding balls. Only by systematically integrating the two factors can we really grasp how to correctly select and use the grinding balls. Skills to achieve the ultimate goal of promoting high-yield, stable production and low consumption of the grinding system.
The metal abrasiveness, friability and grindability of the grinding materials with the same chemical composition will be significantly different due to their internal cleavage, natural crack development and degree of weathering. Don't say that from different mining areas, even the ore of different mining faces in the same mining area will change the grinding ball wear due to the difference in the abrasiveness, friability and grindability of the metal.
The effect of the relative hardness of the material on the wear of the steel ball when the other conditions of the grinding material are the same. In the dry wear, the relative hardness is properly determined, and the wear effect of the polished steel ball is particularly remarkable. The hardness of the steel ball should be selected according to the hardness of the material, and the hardness of the steel ball and the material should be matched in the production.
As the particle size of the milled material increases, the wear of the grinding balls also increases. However, as the material size continues to increase, the material separates the steel ball from the steel ball, reducing the chance of direct contact between the steel balls. Therefore, the wear of the grinding balls is gradually reduced. When the fineness of the steel ball is very fine, it tends to cause the ball to be worn on the surface of the steel ball, thereby reducing the wear of the steel ball. www.grindingballsmedia.com
