Description
Technical Field
[0001] The utility model relates to the technical field of cement ball mills, in particular to a high-efficiency grinding mechanism of a cement ball mill. Background Art
[0002] Cement ball mill is mainly used for grinding finished products and raw materials in cement plants. In the current production process, the interior of the cement ball mill is usually set up with two chambers. A partition plate is installed on the inner wall of the cement ball mill tank. One side of the partition plate is the crushing chamber, and the other side is the fine grinding chamber. Usually the crushing chamber is used as the first chamber, and the fine grinding chamber is used as the second chamber. The rotation of the tank body generates centrifugal force to bring the high-chromium steel balls to a certain height and then fall, which has a heavy impact and grinding effect on the materials. After the materials are coarsely ground inside the first chamber, they enter the second chamber through the partition plate. The chamber is equipped with high-chromium steel balls and steel forgings to further grind the materials.
[0003] When a common cement ball mill is in use, the material flows too fast after entering the tank of the cement ball mill to achieve the grinding and shaping effect, which is a major bottleneck for improving process indicators such as fineness and specific surface area. Therefore, an efficient grinding mechanism for a cement ball mill is proposed to address the above problems. Utility Model Content
