HOSOKAWA – Powder process technologies feature innovative designs for the pharma sector

Hosokawa Micron Powder Systems understands the needs and requirements of the demanding pharmaceutical industry. The company demonstrates this keen understanding by manufacturing powder process technologies with innovative designs for size reduction, classification, mixing and blending, drying, hygienic filling/weighing and high containment applications.

The lineup

The Alpine AS Spiral Jet Mill is just one of the company’s many innovative products for the pharmaceutical industry. It is designed for the micronization of pharmaceuticals and certain chemical powders. The design of this unit enables material, which is injected into the grinding zone by gas nozzles, to flow around the perimeter of the mill wall in a spiral manner. This results in particle-to-particle attrition and impact against the mill walls. As the material gets finer and lighter, the ground particles are drawn towards the outlet at the centre of the milling chamber.

The Alpine AFG Fluidized Bed Opposed Jet Mill is another option. Ideal for ultra-fine size reduction of many materials up to a Moh’s hardness of 10, this mill accelerates compressed gas through a series of nozzles at extremely high velocities, draws particles into the accelerated gas streams and grinds them via inter-particle collisions in the jet stream. To achieve ultra-fine particle sizes down to D97 < 3 μm, the AFG is equipped with a dynamic deflector-wheel air classifier that can be operated at varying speeds to alter product fineness.

The Mikro UMP Universal Milling System is also available. This compact, high-speed impact mill is capable of coarse granulation or fine size reduction with interchangeable rotor configurations. It provides the same grind as the classic hammer mill, but offers the flexibility of a pin disc, knife rotor or attrition plates. This unit is energy efficient and economical to operate.


Hosokawa serves the global pharmaceutical market. In Canada, its products are available through Firing Industries. These products are in compliance with all of the associated industry requirements of the FDA’s GMP specifications.
