Roller Mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or ointments and some solid materials. The rollers rotate at different speeds and the material is sheared as it passes through the gap.
To obtain the desired particles size, the following should be controlled –
- The gap between the rollers
- The speed differential between the rolls
- Feed rate
All pairs of rollers in a roller mill have one slow mill and one fast one. The rolls turn in opposite directions, toward each other, pulling the feed between them. The cut, depth, and spiral of the corrugation, together with the rotation differential, determine the aggressiveness of the milling at any particular step.
We also offer Hawk Roll Mill Exchanges and Rolls on Lease.
- Produce more uniform, less fines and oversized particles when it comes to product quality.
- Generates less heat (0-30C) unlike hammer mill that generate up to 100
- Less moisture loss
- Better work environment due to low machine noises level.
- It is energy efficient/energy saving
- Reducing working hazard due to dust generation from the milling material.
