The physical function of grinding steel balls

It plays a huge role in the development of the national economy. Under some special conditions, steel balls of special materials are often needed to fulfill the functions required under different environments. In fact, some special material steel balls have been widely used in various fields of the national economy. Their promotion and application have not only promoted the development of the grinding steel ball production industry, but also promoted the technological development and technological progress of related industries. So do you understand what it does?

1. Impact force: When the impact energy generated by the grinding steel ball exceeds the strength limit of the material, the material will be crushed, but the excessive impact force applied to the ball mill liner and cylinder also increases the stress and the energy consumption is also large, so it is selected When grinding steel balls, the impact factor must be considered first. The wear-resistant production of ball mill grinding steel balls has undergone repeated tests. The impact value of high chromium balls is ≧4.0 (J/cm2), the hardness of the ball table is ≥58HRC, and the hardness difference of the ball table core is controlled at 2HRC, which can meet the needs of customers using the ball mill. Sexual needs.

2. The number of impacts: the number of times is the main means to improve the fineness and output of grinding. The impact force, number of impacts and material storage capacity of grinding steel balls depend on the ball diameter of the ball mill. With a professional falling ball testing machine, the ground steel balls produced are tested repeatedly, and the falling ball impact fatigue life of the high chromium balls is calculated to be ≥ 15000 times, which fully meets the requirements of customers.

3. Grinding force: During the operation of the ball mill, the material is ground by the point-to-surface contact of the grinding steel ball, thereby improving the grinding efficiency, especially for the fine grinding chamber that relies on the grinding action to grind. The hardness and wear resistance of the high, medium and low chromium alloy cast balls produced by wear resistance far exceed the industry standard, and the hardness of the ball table and the center of the ball.

The above is an introduction to the physical effects of grinding steel balls, I hope it will be helpful to everyone.
