Cement Ball Mill
Cement ball mill is mainly used in the grinding of finished products and raw materials in cement plants. It is also suitable for industrial and mining enterprises such as metallurgy, chemical industry and electric power to grind various ores and other grindable materials.
advantages
- High stability, a number of new patents: CHAENG double belt belt mill is the first company in China to solve the problem that the mill can not run continuously due to the high temperature of the belt bushing during unloading. And obtained the national utility model patent, patent number: ZL201020285841.9. Many examples prove that the CHAENG cement ball mill can operate stably for a long time.
- The structure is novel and the production capacity is strong: CHAENG cement mill adopts the latest and unique streamline design in the world, which reduces the ventilation resistance, increases the effective volume, makes the discharge easy, and improves the output of the mill. The mill liner adopts a combined structure design, and different liner structures are adopted at different stages of the raw material grinding, which greatly improves the milling efficiency. The drying capacity of the material can reach 10%~15%.
- The specific surface area of the finished product is 3300-3800cm2/g: the specific surface area of the cement produced by the CHAENG cement plant is 3300-3800cm2/g. Compared with other mills in the same industry, CHAENG cement mill has the advantages of high product fineness, large specific surface area, fast hydration reaction and fast strength development.

working principle
The material is uniformly inserted into the first chamber of the ball mill by the feeding device through the hollow shaft of the feeding material. The chamber has a step liner or a corrugated liner, which is filled with steel balls of different specifications, and the cylinder rotates to generate centrifugal force to bring the steel ball to a certain height. Drops, causing heavy impact and grinding on the material. After the material reaches the rough grinding in the first bin, it enters the second bin through the single-layer partition plate. The bin is embedded with a flat liner with steel balls inside to further grind the material. The powder is discharged through the discharge raft to complete the grinding operation.
The main working part of the ball mill grinding material occurs on the horizontal low-speed rotating cylinder. When the cylinder is driven to rotate by the transmission device, the grinding body is attached to the lining surface of the inner wall of the grinding machine cylinder due to the inertia centrifugal force. After being rotated together, after being brought to a certain height, it is free to fall by gravity. At this time, the grinding body crushes the material in the cylinder, and at the same time, the grinding body has a rising and falling circular motion in the rotating mill, and also generates Sliding and rolling, causing grinding between the abrasive body, the lining and the material to be ground to make the material fine. While the material is subjected to impact crushing and grinding and grinding, the height difference of the material surface of the material feeding end and the discharging end makes the material flow slowly from the feeding end to the discharging end to complete the grinding operation.
