Fluidized bed air jet mill Atritor

The Atritor Opposed Jet Mill is probably the most efficient fluid energy mill available. Unlike many mills of this type, it directly entrains the feed material into the high pressure gas for maximum acceleration to near sonic velocity before two opposing streams impact directly in a compact grinding chamber.

The energy imparted to the accelerating particles is instantly expended in inter-particulate collisions and no energy is wasted.

Specific energy consumption is significantly lower than comparable systems.

The grinding chamber is lined with tungsten carbide for maximum resistance to abrasive materials.

An independent classifier is used to ensure the most efficient separation, uncompromised by interference from the grinding process. The oversize fraction is recycled to the grinding system.

Products with top sizes less than 10 microns and mean particle sizes of less than 2 microns are typical.

Dry, oil-free compressed air ensures an uncontaminated product. For heat sensitive materials the air is cooled or hot air will provide some drying capability.

The system is fully automated for un-manned operation.

Each plant is custom designed to specific performance requirements with individual line capacities up to 2t/h.
