Working principle of different grinding mills Raymond mill is a kind of common grinding equipment. On the basis of economic and technological development, Raymond mill has developed into several special types, such as powerful mill, ultrafine mill, and high-pressure mill.
As a powerful mill, it adopts a high-pressure device on the basis of ordinary Raymond mill, and a high-pressure spring is set in the grinding device to increase the grinding pressure between the grinding roller and the grinding ring by 1.2 times. When the grinding roller and ring are worn to a certain extent, the length of the highpressure spring is adjusted to keep the constant grinding pressure between the grinding roller and ring, so as to ensure the stable quality. At the same time, in the grinding device, through technical improvement, the contact area between the grinding roller and the grinding ring is large, which avoids the phenomenon that small particles can not be continuously crushed in the uneven gap in the general grinding machine.
