The ball mill's working efficiency directly affects the concentrator economic benefits of the beneficiation factories. As a result, it would be necessary to improve the working efficiency of it.
Ball mills are common grinding equipment, which are composed by feeding parts, discharging parts, turning parts as well as driving parts. In modern industries, they are widely used in crushing materials such as concrete, silicate products, refractory materials, and constructional materials. There are various types of ball mills so we should choose proper ones when we deal with different kinds of mines. Besides, there are many factors that can influence the working efficiency of ball mills. What measures we can take to improve the working efficiency of ball mills is the foremost concern for both manufactures and users. Let's explore these factors together and find out several useful methods to improve the efficiency.
The construction and features of the mines can cause heavy effects on the efficiency of ball mills a lot. Facts prove that the raw ores of big particle and inattentive structures are easy to grind. As a result, the diameter of the steel balls has an effect on the grinding results. That means we should choose proper size of steel balls according to the grain composition. Only by choosing steel balls of right diameter can we grind the raw ores completely. Otherwise, the grinding results may not be able to reach our requirements. The way to operate the ball mills is another important factor that can influence the working efficiency. So operators should be strictly trained. First of all, operators should mix proper amount of water with the raw ores. If we apply the ball mills to grind dry raw ores, the efficiency may be low. Keeping appropriate humidity of raw ores can ensure the quality of our products and high efficiency of grinding process. Besides, we should increase the electric current as much as possible before it reaches the maximum current rating. The reason is that the increase of electric current can improve the rotational speed of ball mills. As we know, the rotational speed of ball mills can directly decide the grinding efficiency. If we can install frequency modulators to the ball mills the rotational speed will be increased significantly. However, the rotational speed can't be too high. Nowadays, the ball mills are widely used in grinding raw ores because of its high efficiency and good quality. Pay attention to these methods that can increase the efficiency while using ball mills. We believe ball mills have a bright future and will be applied to more fields in the near future.
