Technical Field

The invention relates to the technical field of ore processing equipment, in particular to a Raymond mill for mine stone treatment.

Background

The main components of the Raymond mill are a stationary chassis and a grinding roller which rotates. The edge of the chassis is provided with a grinding ring. When the grinding roller rotates around the vertical shaft, the grinding roller is pressed on the grinding ring under the action of centrifugal force, the scraping plate rotating together with the grinding roller spreads the material on the chassis between the grinding roller and the grinding ring, and the material is crushed under the extrusion and grinding actions between the grinding roller and the grinding ring.

Firstly, the grinding roller applies pressure to the materials on the grinding ring under the action of centrifugal force, the grinding roller is taken as a whole, the gap between the grinding roller and the grinding ring is determined by the materials with the maximum diameter, when the diameter difference of the materials is large, the grinding roller only acts with the materials with the maximum diameter at the same moment, namely, the materials processed at the same moment are less, and the working efficiency of the Raymond machine is restricted.

Because the grinding roller uses the quincuncial frame connecting point at the top to make the pin joint that sways, therefore, the lower extreme is less from the interval of grinding ring when swaing, consequently, the friction of the lower extreme of grinding roller and material is more frequent, and pressure is bigger, and the wearing and tearing is faster, has reduced the life of grinding roller.
