ball mill is a common pulverized device in the mineral operation. The steel ball is the main grinding medium of the ball mill. In the long-term grinding process, steel balls are inevitably generated. The following from the professional perspective to explain the process of ball mill steel ball corrosion wear and the phenomenon and precautions of steel ball micro-wear, I hope to help users.
When the material acts in active or corrosive grinding, corrosion and mechanical wear also cause the ball mill partial loss, and there are mutually promoted effects. The ball mill steel ball loss produced under this condition is often referred to as corrosion wear. Corrosion products produced after chemical or electrochemical reactions in material and ball mill steel balls, generally with the binding of the mother surface, and when the surface of the ball mill is interacting with the material, the corrosion product is easily grinded, and the new The metal surface provides conditions for further corrosion. In this way, corrosion-wear-corrosion is alternately, which produces a metal loss above dry mill.
When the ball mill wet operation, the wear of the ball mill steel ball and the ball mill liner, the wear of the sand pump and the impurity pump impeller and the outer casing, and the wear of the engine cylinder line is corroded.
The mechanism of corrosion wear is more complicated. Due to the diversity of environmental media, mechanical wear and corrosion abrasion alternate, there are many factors involved, and it is difficult to propose a mechanism that can summarize all aspects, but through research, test, some important factors affecting the process of corrosion wear. Learn. It is understood that three main factors that produce corrosion wear on ball mill steel balls are: the nature, environment and temperature of the ball mill steel ball.
Detailed to understand the internal and external factors that cause the ball mill steel ball to produce corrosion wear, in the application, according to material conditions, the ball mill steel ball properties can be used to reduce the distribution ball mill steel ball. Corrosion and wear, extend the life of the ball mill steel ball.
