Cement Mill

1 Ordinary cement ball mill: ordinary cement ball mill is mostly used in the circle flow grinding system, which is characterized by high grinding efficiency, large mill output and power consumption, especially when grinding slag cement, the performance is more prominent. Generally, the output of the mill can be increased by 15-20%, the power consumption is reduced by about 10%, in addition, the finished product temperature can be reduced by 20-40 ° C, and the fineness of the product is also easy to adjust.

2 High fine and high yield cement ball mill: High fine and high yield cement ball mill is mainly used in open flow grinding system. It is characterized by simple system equipment and process flow, less investment, and less plant area; In the mill structure, the advanced special separator device for internal powder is used, the activation device is added to the fine grinding bin, and the grinding end has a special discharge grate, which minimizes the size of the grinding medium in the grinding bin, greatly improves the grinding efficiency, and achieves the purpose of high output and low energy consumption.

Information

It can be used for open flow grinding, and it is also suitable for circulating flow grinding composed with powder separator. Cement grinding has the characteristics of strong adaptability to materials, continuous production, large crushing ratio, and easy speed regulation of fineness of grinding products. The cement ball mill can be produced by both dry method and wet method, and can also be operated at the same time as grinding and drying.

The material is uniformly entered into the first bin of the ball mill by the feeding device through the feeding hollow shaft. There are stepped lining plates or corrugated lining plates in the bin, and steel balls of different specifications are installed inside. The centrifugal force generated by the rotation of the cylinder will bring the steel balls to a certain height and then fall, which will have a heavy impact and grinding effect on the material. After the material is coarse ground in the first bin, it enters the second bin through a single compartment plate, which is lined with a flat liner plate and contains a steel ball to further grind the material. The powder is discharged through the discharge grate to complete the grinding operation.

The main working part of the grinding material of the ball mill occurs on the cylinder of horizontal low-speed rotation. When the cylinder is driven by the transmission device to rotate, the grinding body, due to the action of inertial centrifugal force, is attached to the lining surface of the inner wall of the mill cylinder and rotates together with it. After being brought to a certain height, it falls freely under the action of gravity. At this time, the grinding body will crush the material in the cylinder. At the same time, the grinding body in the rotary mill in addition to the rising and falling circular movement, but also produce sliding and rolling, resulting in grinding between the grinding body, the lining plate and the grinding material to grind the material fine. When the material is crushed and ground by impact, the material itself flows slowly from the feed end to the discharge end by the difference in the height of the material surface between the feed end and the discharge end to complete the grinding operation.
