for our Powder Processing equipment



The Hosokawa powder finisher is a high capacity continuous de-agglomerator (crusher) that can be used to process bulk powder flows. The Hosokawa powder finisher works using a high-speed rotor over a screen assembly to create collision forces and friction for efficient and fast de-agglomeration.

Depending on the characteristics of the powder, (texture and grain size) the Hosokawa powder finisher can crush powders to anything ranging from 500 to 2000 microns. The Hosokawa powder finisher processes powders with a capacity of up to 40 m³ per hour.

The finisher is available for testing. 50 to 100 kg with a density of 0.5 kg/l are required.

Working principle

The base powder is fed in doses into the rotor chamber. As soon as the product reaches the rotor, it is forced through the sieve plate in the bottom section of the finisher at high speed. Coarser particles which cannot fit through the sieve are then broken by the impact of the rotor.

  • Models

    The Hosokawa powder finisher is available in two main designs: the FD series, which is a heavy duty design with a bearing on both sides for high stability at high capacities, and the FS series with a bearing on just the side of the motor. This makes it easier to mount an inspection hatch, and simplifies inspection and cleaning, as well as easy removal of the sieve and rotor without having to extract the full finisher from the process line. The inspection hatch can be locked electrically or bolted.
