According to years of multi-ball mill production, the steel ball level is summarized in the ball mill, determined by the following factors:
1. Determine according to the particle size, hardness, easy mill, and fineness requirements of the product. When the material particle size of the ball mill is small, it is easy to wear. When the product is required, we need to strengthen the grinding of the material, and the selected steel ball is small. Conversely, if the material particles are large, we must strengthen the impact of the material, and use large diameter steel balls.
2. Mixed steel balls coordinated by large steel balls are larger than mixed steel ball gaps that cooperate with the little ball. In order to control the flow rate of the material in the ball mill, the size steel ball is usually used. Suitable to reduce the gap between the steel ball, so that the flow rate of the material in the ball mill is slowed down, and the time of the material is extended in the ball mill and improves the efficiency of the polishing. Do not excessive levels of steel balls. Different diameter steel balls have different linear velocities to produce natural layers in the inner layer in diameter. It has intensified the hierarchy to affect the efficiency of the grinding.
3. Select the diameter of the steel ball, there is a certain relationship with the amount of unit volume material in the ball mill. At closed circuit polishing, the removal of the powder mill increases the amount of unit volume material in the ball mill, and the steel ball is subjected to a certain buffer at the impact. The cycle is high, and the steel ball is large, and it is small. (The article is published by the ball mill equipment. The article is for reference only)
4. The surface shape of the ball mill is also affected by the steel ball. The surface shape of the liner has insufficient ball capacity, and the height of the steel ball is lowered, the impact force is reduced, and the diameter of the steel ball should be large.
Through the above analysis, we know that there are many factors affecting the ball mill steel ball, and the grade of the steel ball is relative, temporary. Users should consider the grade problem of steel ball in the ball mill based on a variety of factors to achieve their own ideal product fineness.
