Steel Ball

Introduction of Steel Ball

Steel ball is the grinding medium filled in ball mill. The grinding operation of ball mill is completed by steel balls, so the steel ball quality is crucial. According to the feedback results for many years of manufacturing experience, the steel ball produced by our company has the following characteristics:

1. High hardness, wear-resistant.

2. High impact toughness, which cannot cause crack.

3. Various product specifications, the specific shape and size can be customized.

4. The material of steel ball is diversified, which can select different materials according to the actual production needs.

5. The production process is rolling or forging steel with high density.

As an essential part of ball mill, steel ball is widely used in all kinds of metal mines, gold, silver, copper, iron ore, thermal power plant, pellet plant, coal, cement, chemical industry, etc. What affect the grinding effect of steel balls?

1. The filling rate of steel balls.

Because the grinding of ball mill is completed by the repeated beating, then the ball filling quantity naturally determines its grinding effect. If it is loaded many balls, it will hit many times, and the grinding effect will be strong, which leads to high production efficiency. If the ball is less, the impact will be less, thus the grinding effect is weak and the production efficiency is relatively low. But it is not right that if there are more balls, the production efficiency will be higher. If the filling amount us just more than a maximum number, the feed rate will be reduced, and then the production efficiency will also be reduced.

2. The size of the ball.

With a certain speed and filling rate, the size will have a very big impact on the grinding effect. If the steel ball has too large size, it will lead to less impact, small contact area and large gap, which will direct cause low productivity and the particle size of the product will not be uniform.

3. Ball density.

The larger density it has, the harder the ball will be. Much harder ball is not better, but certain hardness value is proper. Too hard balls will cause serious ball rebound, which will weaken the grinding effect of mineral particles.

4. The materials of steel balls.

Because the ball is for hit operation, it will generate large amount of powder, although the amount is small, it still has a great influence on the subsequent process, especially the follow-up treatment of chemical reaction, it will affect the whole ore dressing effect, so you must use different steel balls according to different materials.
