Summary:The ball mill is a common mineral processing equipment in the industry. Its working principle of the cylinder and the lining plate of the cylinder work together

The ball mill is a common mineral processing equipment in the industry. Its working principle of the cylinder and the lining plate of the cylinder work together to raise a part of the steel ball to a certain height, and the free fall movement generates impact force, which hits the material in the cylinder and completes the grinding operation. . Among them, the steel ball is a very important accessory. Because of its high consumption, it has strict requirements in terms of quality and quantity.

Ball Mill Steel Ball Model

The ball mill is a horizontal cylindrical device with a steel ball grinding medium inside. Under the operation of the ball mill, friction occurs between the steel balls and the ore material, and the friction and impact between the balls separate the pigment aggregates. The impact effect of the ball mill, the ore material inside the ball mill is impacted and broken, and the effect of the lining plate, the ore material is ground into small particles. The steel ball of the ball mill plays a vital role in the grinding process. The type, size, hardness and strength of the steel ball directly affect the grinding effect.

When purchasing a ball mill, the mill manufacturer will configure a suitable amount of steel balls for the user, but the steel balls are subject to very large wear during the processing process. Therefore, after a period of use, a new batch of steel balls needs to be replaced. Otherwise, the ideal grinding effect will not be produced.

Ball Mill Steel Balls

The amount of balls loaded in the ball mill is a key factor affecting the grinding effect. During processing, the overall efficiency of the ball mill depends on the efficiency of a single steel ball. In order to improve the overall grinding efficiency, each steel ball must perform a higher work. Efficiency, and to improve the working efficiency of steel balls, it is necessary to determine the optimal amount of balls.

Remind everyone that the filling amount of the steel ball is about half of the apparent volume. After the abrasive is added, the amount of material is just enough to immerse the ball and rotate at an appropriate speed. The filling amount of steel balls in a ball mill is determined by a combination of several data, such as the size of the steel balls, the volume of the cylinder, the power of the ball mill, the hardness of the mineral material, etc. After determining the optimal amount of balls, the user can ensure that as long as the user operates according to the regulations Get high returns.
