Nowadays, the grinding equipment widely used in the market is basically Raymond pulverizer and high pressure roller mill. Because of their unique characteristics, they are favored by many customers. But there are still some differences between them. Let's learn about the difference between Raymond mill and high pressure roller mill.
There is no difference in the appearance of the main engine of Raymond pulverizer and suspension roller mill, but the main difference lies in the inlet and outlet and output. The working principle of these two equipment is in fact almost the same, but there is a high pressure spring in the high pressure roller mill. During the process of working, because of the effect of the high pressure spring and the centrifugal force, the roller will benefit the grinding ring rolling, its rolling pressure will be 1.2 times higher than Raymond mill under the same condition, and the output can be increased by 20%. - 30%. when the grinding roller and the grinding ring are worn out at a level, the constant rolling pressure between the roller and the grinding ring is maintained by adjusting the length of the high pressure spring to ensure the stability of the output and fineness.
Regarding the feed particle size, the smaller the feed particle size of Raymond mill is, the more stable the output is, and the higher the efficiency is. The feed size of high pressure roller mill is larger than that of Raymond mill. As for the output size, the ouput size of the Raymond grinding mill is basically kept between 30-325 orders. The output size of the high pressure roller mill is between 80-425 mesh, and the powder size is finer. In terms of yield, the output of high pressure roller mill is higher than that of Raymond mill.
