Main Parts Of Raymond Mill

Main parts of Raymond mill include grinding roller, grinding ring, powder collector, classifier, air blower, reducer, base plate, shovel, Raymond mill pendulum, star stack, etc.

Parts And Their Functions

Grinding Roller

Raymond grinding roller materials usually are made of alloy steel, alloy carbon steel, ZG65Mn manganese alloy steel, ZGMn13 high manganese alloy steel.

Among them, alloy steel and high-quality alloy carbon steel have better wear resistance and are suitable for softer or low-hardness materials.

Functions Of Grinding Roller

The feeding material is ground by two forces: one is a mutual force from the revolution of the grinding ring plus the friction of the grinding roller itself, and the other is outward centrifugal force from the rotation of the grinding roller.

Grinding Ring

The material used to make the grinding ring is the same as grinding rollers. Most Raymond mill manufacturers are more likely to apply manganese alloy steel due to its good wear resistance and low cost.

Grinding Ring Function

The grinding ring is also the basic accessory. The grinding roller squeezes the grinding ring under the centrifugal force to crush the material which is shoveled to the space between the grinding roller and grinding ring.

The role of the grinding ring is to cooperate with the grinding roller to complete the grinding process.

Classifier

Mainly used to control the powder fineness of Raymond mill.

Classifier Of Raymond Mill

Driven by the motor, the classifier going through the two-stage deceleration rotates the blades of the turntable then classified the powder into different sizes.

Air Collector Of Raymond Mill

In the air collector, powder separates from the air and falls from the discharging port. Air with fines enters the dust collector and is released out after being processed.

The normal operation of Raymond mill relies on the cooperation of various parts. So, if the finished product is too fine or too coarse, it will not be caused only by one part but by poor fit.
