for Powders & Bulk Solids



The Extrudomix mixer/extruder is an efficient combination of high shear mixer and low to medium pressure extruder that kneads, mixes and extrudes in one continuous process; as a standalone unit or in combination with other process equipment.

It is ideal for mixing solids and liquids into very viscous and homogeneous pastes as well as plastic masses.


The Extrudomix mixer/extruder has a single horizontal shaft with blade segments arranged in a spiral pattern that move the material through the chamber. Material is fed into the housing at one end and forced forward by the rotating blade segments until it comes in contact with the stationary anvil. Stationary anvils attached to the housing and inserted between the rotating blade segments prevent the material from rotating with the shaft.

The resulting effect is continuous kneading and mixing, followed by extrusion through a variety of die which are available in different shapes and sizes. The Extrudomix mixer/extruder has better particle dispersion in comparison to higher pressure systems. It is also less expensive to buy and less expensive to operate.

Hosokawa Micron has been developing innovative solids processing systems for more than a century. As a result, we can draw on an unparalleled amount of know-how when designing new powder mixing systems. In a powder mixing system, the equipment, process steps and interacting parameters must all work together as an integral solution in order to ensure the optimal functionality, quality and efficiency of your total system. That's why we carefully select, configure and integrate all the components and processes when designing a powder mixing system.


Hosokawa Micron powder processing Test Centre in Doetinchem (Netherlands)

Our test and process development centre in the Netherlands offers unique possibilities for testing your product to determine the most efficient process, system or plant prior to final design. We can provide laboratory-level as well as production-sized trials.

Whether you wish to test a single machine or a complete powder processing system, the same skilled and experienced staff are here to help ensure that your requirements are met, and that you are entirely satisfied with the results.

We offer process equipment and technologies from individual units to large scale bespoke system solutions. Our principle is to deliver high performance yet affordable solutions that meet our customers' demands and long term challenges.
