High Speed Rotor Mill / Super Rotor / Blade Mill

Applications
Highly efficient, fine particle
processing system.
Particle sizes reduced from several mm’s toseveral microns. The Super Rotor, with low
operating cost and the ability to pulverize whilecollecting a narrow particle size distribution, is
an optimal machine for producing high valuedadded powders in the fine range.

The Super Rotor- optimal for fine pulverizingof resins etc.. The Blade Mill-allows
pulverization of elastic fibrous materials. Inthe gap between our fixed liner andproprietary high-revolution rotor withgrooves, a strong swirling-action is created,which yields high-efficiency fine pulverizing.

The Super Rotor / Blade Mill is a unique rotor which makes
possible stable pulverizing and long-term low-cost operation.
Fine pulverization of powder can be achieved without overpulverization, and the range of the finished powder will be verynarrow.

The grooves made with a proprietary
design create a swirling action resulting
in finely pulverized powder.
The blower creates negative pressure within thePulverizer, causing the raw powder to pass through thegap between the rotor and the liner. The swirling action

Ability to pulverize various typesof powders
In addition to the standard configuration which has
produced considerable results, the addition of a cool-airsystem and a brine circulator, low-heat pulverization
can be performed. All areas that come into contact withthe powder are abrasion-resistant, e.g. sintered
Tungsten Carbide, and thus can also pulverize metals
and ceramics.
