Raymond mill can crush more than 280 kinds of materials with Mohs hardness not greater than 9.3 and humidity less than 6%, such as limestone, aluminum ore, kaolin, ceramics, etc., and the discharge particle size is arbitrarily adjusted between 80-325 mesh. It is widely used in mining, chemical industry, building materials, smelting, ceramic factory and other industries. Moreover, it is very important to feed particles when the pulverizer is working, and the particle size of the feed is controlled below 5cm. Will the feeding amount of Raymond machine affect the milling output? The following is a simple analysis of Xiaobian.

If the particle size of the finished product processed by Raymond mill needs 300 mesh, if the feed particle size of the material is a mixture of less than 3cm, the output will be higher, and the grinding layer of the material is larger, which is easy to grind.

Then, if the fineness of the material has reached 100 mesh and the grinding needs to be continued, the grinding layer of the material is small at this time, and the output will be low compared with the feed below 3cm. From this lesson, it can be seen that the feed particle size of materials is not the finer the better. On the contrary, the mixed materials with particles and powder have larger grinding layers and higher output. However, the larger the material, the better. The feed particle size below 3cm is appropriate. If the material is too large, it is easy to wear the grinding roll and ring.

Under the action of centrifugal force, the grinding roller of Raymond mill is rolled by suspension roller and air selected to achieve the crushing effect. One feeding and one pulverization make it convenient to adjust the fineness. If the particle size of the finished product of the material is required to be finer, the production efficiency of Raymond mill will be greatly affected. The grinding time is long, the grinding efficiency is low, and the output will decrease. The feeding size of the equipment is limited. When the material to be ground is large, the burden of the equipment is increased, or the equipment is blocked, resulting in downtime and maintenance, which greatly reduces the production efficiency and output. Therefore, the feeding particle size should be uniform, so as to improve the output and increase the benefit.

The pulverizer achieves the fineness of air separation through the joint action of fan and analyzer. If the fineness is not reached, the materials will continue to be grinded in the working chamber of the host machine. For materials with fineness of more than 200 meshes that need to be processed, air separation is a more appropriate choice. If screening equipment cannot be selected, it is easy to cause equipment blockage, and screening will block the screen.

The air separation effect of Raymond mill is controlled by adjusting the air volume of fan and the speed of analyzer, which is very easy to use. Under normal production conditions, Raymond mill should also pay attention to the control of feeding speed. It should not be too fast or too slow. Only by feeding evenly can Raymond Mill operate normally.
