These are centrifugal mills with a vertical axis, suitable for tertiary or quaternary crushing of even highly abrasive inert materials.
The high-speed auto-crushing process that develops in these machines allows the requalifying of inert material with a rather flaky shape, improving its polyhedral shape and increasing its mechanical resistance.
The particular configuration of the feeding and crushing chamber creates an air turbulence which optimises the work performance and, by separating the material from the dust, facilitates dust removal downstream.
The crushing chamber is subject to limited wear, since the impeller is coated with the same material deposited in the machine.
The impellers have different dimensions, depending on the final product required.
Thanks to the reduced replacement of parts subject to wear and to centralised lubrication, maintenance is very simple and machine down times are very short.
