        Where are wear-resistant steel balls used?

        Release time:2021-11-19  
        Wear resistant steel ball is a kind of consumable. It is mainly used to grind materials to make them finer to meet the use standard. It is mainly used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical industry and other fields. It is used in a large amount in China. China is a big steel ball consumer.

        Wear resistant steel ball is a kind of consumable. It is mainly used to grind materials to make them finer to meet the use standard. It is mainly used in mines, power plants, cement plants, steel plants, silica sand plants, coal chemical industry and other fields. It is used in a large amount in China. China is a big steel ball consumer.

        There are three kinds of wear-resistant steel balls: forged steel balls, cast steel balls and hot-rolled steel balls.

        We often say the use of wear-resistant steel ball. Generally speaking, it is the basic use of wear-resistant steel ball. Now it is basically three aspects.

        For adding ball

        With the continuous operation of the ball mill, the steel ball is constantly worn, and the optimal ball load of the steel ball is also changing. Therefore, it is necessary to add balls regularly to maintain the proportion during initial loading. It is a new method of balancing ball filling, which is proved to be feasible by practice.

        Size ball diameter ratio

        In addition to determining the total ball loading capacity, the most important thing is to determine the steel ball size of the largest ball and the smallest ball initially loaded according to the particle size characteristics of the grinding ore, and then determine which kinds of balls need to be loaded and their proportion. Generally, coarse ore particles shall be hit by large steel balls, and fine ore particles shall be milled by small steel balls. If there are too many big balls and the grinding is not fine, it is manifested as "under grinding". On the contrary, too many small balls, large surface area and over crushing will increase. At the same time, due to too few large balls and insufficient ball striking force, the so-called "over grinding and under grinding" will be formed. Therefore, it is very important to correctly determine the size of the largest and smallest ball for reasonable ball loading and improving grinding efficiency.

        Suitable ball diameter

        After studying the motion of the steel ball in the cylinder of the ball mill, it is found that it is equally important to determine the steel ball size of the smallest ball and the largest ball. On the basis of a certain formula, the problem of suitable ball diameter can be solved by selecting the priority number of preferred ore particle size and required steel ball size. According to the actual situation of the materials to be ground, the particle size is grouped, and the steel ball size required by each particle size group and the yield of each particle size group are calculated.
