Laboratory Mixer for Dry Powders – Hosokawa Micron Labomixer

The Micron Labomixer is a laboratory scale conical screw mixer designed to gently mix dry powders and liquid additives in batches up to 2.5 liters. Its operation is similar to the well-known Nauta Conical Screw Mixer using a rotating screw along the inner wall of the revolving inverted cone type mixer. The small-batch unit is suitable for chemicals, minerals, foods, pharmaceuticals, plastics, and cosmetics.

The video describes many of the key features of the Labomixer which is based on the Nauta Conical Screw Mixer principle. The Nauta mixer works by creating convection current inside the batch of material that thoroughly and gently moves the material. The auger pulls material up and deposits it higher in the batch. The location of the auger is changed by the orbital arm which moves the auger at a relatively slow speed around the periphery of the mixer.

Simple and efficient operation

Operation of the Labomixer is simple and mixing is fast and efficient. The mixing bowl has a 2.5-L capacity and it mixes effectively at 30% of volume. The bowl rotates at 4 rpm and the mixing screw is variable between 100 and 200 rpm. Both the bowl and screw are made of stainless steel 304. During operation, the Labomixer has a safety mechanism that disengages the bowl and screw if the doors open.

The video describes the few steps that are required for disassembly so material can be discharged or recharged. The compact design is maintenance-free, requires no lubrication, and is well suited for laboratory environments. The simple design is ideal for easy cleaning.
