Roller Mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids to cracked grain, flour for wheat to rice or oil from nuts to grist 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 or constant crush between the rolls.
- Feed rate.
The gearing of rollers in a roller mill have 2 options – one slow mill and one fast one for differential for shearing or rolls running at same speed for flattening / flaking. The rolls turn in opposite directions, toward each other, pulling the product 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.
Capacity is generally dependent on required particle size of the reduced material, with coarser products produced at higher rates.
A statically and dynamically balanced runner head assembly, precise machining and alignment of the discs, and constant spring pressure combine to maximize uniformity of the reduced material.
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.
