Raymond Mill Star Frame

The star frame is the core supporting part of the Raymond mill. It is named after its plum-blossom-shaped branched structure. Fixed at the top of the main shaft and suspended inside the grinding chamber, it supports the total weight of the mill roller assembly, rotates synchronously with the main shaft, transmits power from the main shaft to the mill rollers and drives the mill rollers to revolve. It serves as the key link connecting the power system and grinding components.

Features and Advantages of Raymond Mill Star Frames

Stable and Reliable: Adopting integrated central support design, it ensures smooth operation of the Raymond mill and reduces vibration and noise.

Heavy Load and Pressure Resistance: Made of high-strength cast steel, it features excellent rigidity and deformation resistance. It will not crack or deform under long-term heavy-load working conditions.

Improved Efficiency: The vertical swing star frame enables maximum surface contact between mill rollers and grinding rings. Centrifugal force is fully converted into grinding force with high energy utilization rate. The constant grinding area guarantees stable output regardless of mill roller wear.

Maintenance Tips for Raymond Mill Star Frames

Lubrication Inspection: Check the lubrication condition and wear clearance of the central shaft sleeve regularly in daily maintenance to ensure flexible hinge points without jamming.

Tightening during Shutdown: Calibrate the concentricity between the star frame and main shaft when the machine stops, and retighten all connecting bolts to the specified torque.

Regular Material Cleaning: Remove accumulated materials on and around the frame regularly, and inspect the frame body for cracks or deformation.
