The m-series mill M600

How it works

The mill comprises an upper material in-feed chamber (1) onto which is mounted the drive motor (2), grinding modules (3) and a lower material out-feed cone (4). The machine is mounted onto a fabricated base frame (5) and located on anti vibration mounts.

Material enters the machine through the upper in-feed chamber, passing through the grinding modules (3) where it is progressively reduced in size, exiting the machine through the out-feed cone (4).

The multi stage grinding process comprises in the example illustrated two grinding modules, each featuring a central shaft (6), spreader plate (7) and arbour, onto which are mounted six rollers (8) linked to swinging arms (9). When the shaft is rotated, centrifugal force causes the rollers to move outwards, bringing them into contact with the inner face of the grinding chamber (10) which in turn, causes them to rotate. The spreader plates throw the material being processed outwards and the material is then ground between the rollers and the grinding module walls. By varying the speed of the rotation of the central shaft, the force of the action of the rollers against the drum can be varied which in turn varies the finished particle size.

Throughput vs size of machine - One of the key features is the size of the module barrel which is linear to output, so a 1200mm barrel can output up to 10 tonnes per hour – a very small footprint when compared with ball mills.

The modules are self contained and can range per application from 1 to 4. The more modules the finer the powder. Module diameter also determines the volume of output - the larger the diameter the greater the output. A standard 600mm barrel produces a very fine powder output at up to 5 tonnes per hour.

The machine is encased in a sound proof cladding.

The m-series mill integrates centrifugal powder milling technology into a dynamic engineered solution for a range of industries and applications.

The patented powder milling process employed in the m-series range of mills is based upon a centrifugal grinding mechanism meeting with the material flow path and roller pattern which maximises grinding efficiency. In essence, low electrical energy input relative to fineness and volume of powder output.
