In the power, coal, building materials, and metallurgical industries, ball mills have a wide range of applications. They are the key equipment for crushing materials and milling. The ball is a consumable part that consumes a lot in the ball mill. The quality and performance of the ball directly affect the working efficiency and the milling quality of the mill. The force analysis of the grinding ball can get the cause of wear of the grinding ball, and then provide a certain theoretical basis for improving the grinding machine. The crushing process of the material in the mill is mainly accomplished by the crushing and impact action of the grinding ball in the barrel during the rotation of the mill. The grinding ball group in the mill rotates in a regular and radial manner with the cylinder. The position of the grinding ball increases with the rotation of the cylinder. When it reaches a certain height, the grinding ball no longer rotates with the cylinder and drops off from the departure point in a parabolic path. The force exerted on the grinding ball is mainly periodic high-cycle stress. The grinding ball is subjected to a large normal reaction force when it is at the low point of the grinding mill, and gradually decreases when the grinding ball rotates upwards, when it separates from the material lining board, etc. Zero force on contact. When the ball is rotated in the ball mill, the ball and the material are lifted to a certain height under the influence of the frictional force, centrifugal force and the bulge of the village plate, and they are disengaged from the lining plate to raise the parabolic trajectory first and then downward. fall. On the one hand, the grinding ball moves in a circle with the cylinder; on the other hand, the collision and honing between the ball and the ball, the ball and the abrasive particles are random relative movements. When the ball reaches a certain height, it hits and crushes the abrasive as a working cycle. In this complex movement, the ball is worn out until it fails due to impact, normal pressure, tangential force, and grinding of the abrasive particles. When the grinding ball is thrown off, the impact energy generated when the outer grinding ball is thrown down is large, that is, the impact force is large.
