The Atritor Micronising Mill is a classical spiral jet mill utilising compressed gas to produce superfine materials by autogenous comminution.

The Atritor Cell Mill is a highly efficient mechanical mill with multiple rotors mounted on a vertical shaft.
The construction is modular, providing great versatility for customised design.
It will produce material with mean particle sizes below 20 microns and can be fitted with an integral dynamic classifier if the control of top size is particularly important.
Product quality is optimised by control of mill speed through a frequency inverter, which also limits the starting current.
As an airswept mill this versatile unit is an effective flash dryer and, in some circumstances, can be fed directly with a slurry, producing a dry, fine powder.
Contact parts can be manufactured in many materials to suit most applications.
The Cell Mill is extensive in its applications, ranging from minerals through chemical, dyes and pigments to foodstuffs.

The Sturtevant Micronizer® is a jet mill employing compressed air or gas to produce particles less than one micron. Inside the Micronizer, precisely aligned jets create a vortex. Material is fed into this vortex along an engineered tangent circle and accelerates. High-speed rotation subjects the material to particle-on-particle impact, creating increasingly smaller fines. While centrifugal force drives large particles toward the perimeter, fine particles move toward the center where they exit through the vortex finder.

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.

The MultiNo®-M/S/M is an efficient as well as versatile opposed jet mill, which apart from grinding also excels in classifying and homogenizing. The working principle is based on the propulsion of particles through the use of compressed air. These particles collide with high speed on each other and are reduced in size. The advantage of the product-on-product milling principle are low wear and very low product contamination.
The unique milling unit MultiNo®-M/S/M is especially used for ultra-fine milling of highly abrasive and sticky materials.

CONDUX CGS 10 and CGS 16 Fluidized Bed Jet Mills, for air jet milling of small batches on a laboratory scale.
The particular grinding principle of this jet mill guarantees a virtually contamination-free, ultra-fine grinding of dry products of all hardnesses. Grinding takes place completely autogenously in a fluidized bed so that no grinding tool wear occurs.
The installed, infinitely adjustable classifier wheel guarantees a defined upper particle size limitation of the ground powder. Grinding results can be reproduced by exactly adjustable machine parameters and can be transposed from the laboratory mill onto a larger, production scale machine.
The complete plant is installed on a base frame and is delivered to the customer where it can be put into immediate operation.
The plant is designed to be modular, so that other modules can be added, such as our ConJet® High Density Bed Jet Mill and High-efficiency Classifier Model CFS / HDS to make a completely versatile laboratory platform.

This innovative air jet mill is capable of fine grinding all kinds of dry products with virtually no contamination.
Through this specialized milling concept, product grinding is entirely autogenous. Gas jets alone create the grinding energy. No tool wear occurs!
An integrated dynamic air classifier in the housing can be infinitely adjusted to the desired fineness. This guarantees exact adjustment of the grinding parameters and reproducible product quality.
Even the hardest of products poses no problem for this machine. In addition, extremely temperature sensitive products such as wax can be processed under continuous operation.
