According to years of multi-ball mill production experience, the steel ball level is summarized in the ball mills to determine the following factors:
1. According to the particle size, hardness, easy milling of the feed ball mill material, the fineness requirements for the product to make sure. 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, select the large diameter steel ball.2. Mixed steel balls coordinated by large steel balls are larger than mixed steel ball gaps that cooperate with the little seat. In order to control the flow rate of the material in the ball mill, the size of the steel ball is usually used. Suitable to reduce the gap between the steel ball, the flow rate of the material can be slowed in the ball mill, extend the time of the material in the ball mill, and improve the efficiency of the polishing. Do not excessive levels of steel balls. Different diameter steel balls have different linear velocities, making the steel ball to produce natural layers and large in the inner layer. It has intensified the hierarchy to affect the grinding efficiency.
3. Select the steel ball diameter and have a certain relationship with the amount of unit volume material in the ball mill. When closed-circuit polishing, the renewal of the powder mill increases the amount of unit volume material in the ball mill, and the steel ball will be 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 collected by the ball mill equipment. The content of 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 strength, 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 details.
