Hosokawa Alpine AFG - The leader in
micronising
Unlike other jet mills, the Alpine AFG relies purely on particle to particle attrition in the fluidised bed of material, and is used in minerals, pharmaceuticals, powder paints, food and chemicals
Unlike many other jet mills, the Alpine AFG relies purely on particle to particle attrition in the centre of a fluidised bed of material This is achieved by focusing three or more compressed gas jet nozzles into the milling chamber thereby accelerating the particles to produce intense particle to particle attrition

Olive stone grinding to produce activated carbon
One of the world's leading producers of activated carbon has installed a complete turnkey milling and process control system from Hosokawa Micron to give them unmanned production 24/7
No particles pass down the high velocity nozzle jets, reducing wear and product contamination.
Consistent control of product particle size is achieved by a variable speed high efficiency air classifier installed in the upper part of the AFG jet mill.
Only particles of the desired size can exit the mill with oversize being returned to the grinding zone.
The classifier can be single or multi wheel, dependant on the process, and can be ceramic lined for abrasive materials.
Gentle low temperature processing of the material is achieved giving a product with a steep particle size distribution and minimum ultrafines.
The Alpine AFG microniser can also be designed for use with sticky, hard to process materials.
The modern AFG consumes less energy than conventional jet mills by up to 50%, is quiet in operation achieving less than 85dB(A), is fully automatic and design ensures minimum wear and product contamination.
The system range comprises 13 standard machines with air volumes from 50 to 11,500 m3/hr.
Each model can be supplied in any of four variations, and customised systems can be supplied for specific applications such as Pressure Shock Proof design and CIP and SIP operation.
Considerable investment in research and development by Hosokawa Alpine over many years has meant that the AFG jet mill has evolved into a dynamic product range.
Over 600 Alpine AFG mills are currently operating worldwide in many industries and diverse applications such as minerals, pharmaceuticals, powder paints, food and chemicals etc, producing many well known products and intermediates.
This established range is backed up by the technical and service expertise of the Hosokawa Micron Group.
