Roller Mills | Milling & Crushing Systems

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.

Features & Benefits:

• Produce more uniform, less fines and oversized particles when it comes to product quality.
• Generates less heat (0-3°C) unlike hammer mill that generate up to 10°C
• Less moisture loss.
• Better work environment due to low machine noises level.
• Energy efficient/energy saving.
• Reducing working hazard due to dust generation from the milling material.

AFS Types of Roller Mills:

• Mobile Milling - Paddock or Bunkers
• AFS Feed Mixing Unit (Australian Made)
• AFS Single & Twin Roller Mills (Australian Made)
• PTO Auxiliary Roller Mill
• Replacement of Chilled (Cast) Mill Rolls 

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 maximise uniformity of the reduced material.
