for Powders & Bulk Solids



The Conical Paddle Mixer (CPM) is a batch mixer, designed for mixing, drying and reaction processes. It is compact, quick, efficient, and suitable for many applications in a diverse range of industries.

The Conical Paddle Mixer is a multi-purpose mixer for processes where high accuracy and fast mixing with limited product distortion are required. Conical Paddle Mixers are available in volumes from 50 to over 15,000 litres.


The Conical Paddle Mixer consists of a conical shaped mixing vessel, equipped with a central paddle rotor. When it rotates, the rotor creates a combination of vertical and axial motion in the vessel.

The paddles guide the product gently to the surface of the batch, where it is dispersed and the gravitational pull at the centre of the mixer forces the product back down to create continuous motion throughout the mixing cycle, even at low speed.

The mixing process can be optimized by controlling the mixing energy, which can be achieved by adjusting the rotation speed. The typical rotor speed of the conical paddle mixer is between 1 and 10 m/s.

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.
