We usually use the ball mill specifications to indicate the size of the ball mill. The model size is defined by the diameter and length of the barrel of the ball mill. For example, the 1530 type ball mill we often say has a barrel diameter of 1.5 meters and a barrel length of 3 meters. . So what is the relationship between ball mill specifications and processing capacity?

In fact, the volume of the ball mill is determined by the diameter and length of the cylinder. Let me first talk about the impact of the barrel diameter on the processing capacity.

The working principle of the ball mill is well understood by everyone. The grinding medium and minerals in the cylinder are driven to move together by the rotation of the cylinder. When the content in the cylinder reaches a high point, it will be thrown off. The material collides with the steel ball to grind the material. Purpose. Therefore, the larger the diameter of the cylinder of the ball mill, the larger the particle size of the impact and the higher the work efficiency.

Therefore, we usually recommend large-scale concentrators to choose a larger size ball mill to replace several small ball mills. The purpose of this is to:

1. The area of a large ball mill is much smaller than that of several small ball mills;

2. The equipment installation period is short and can be put into production at a faster speed;

3. The total mass of the ball mill is relatively small, saving infrastructure costs;

4. Compared with several small ball mills, a large ball mill is more convenient to care and maintain, and has a lower failure rate.

The length of the barrel of the ball mill also plays a decisive role in the processing capacity. When the amount of ore is constant, the longer the mineral stays in the cylinder, the finer the grain size of the grinding product. Because the longer the barrel length, the longer the distance from the feed end to the discharge end of the mineral will be, and it will naturally grind finer, so you should consider the fineness of the finished product when choosing a ball mill model. You can choose a shorter barrel length for rough grinding. The ball mill with longer barrel is suitable for fine grinding.

Through the above introduction, you can understand the relationship between the specifications of the ball mill and the processing capacity. The larger the diameter of the ball mill cylinder and the higher the working efficiency, the greater the processing capacity. The fineness of the grinding determines your Choice of length.
