Conical Paddle Mixer
The CPM conical paddle mixer is a multi-purpose batch mixer designed for mixing, drying and reaction processes with maximum efficiency and minimal product distortion.
Principle of Operation
The CPM Conical Paddle Mixer features a conical vessel with a central paddle rotor that rotates at tip speeds of 1–10 m/s, generating a gentle combination of vertical, axial and radial movement. The paddles lift the product upward along the wall and guide it towards the centre, where gravity draws it back down — maintaining continuous motion even at low speeds.
This controlled, convective movement ensures uniform distribution of all components while preventing product degradation. The mixer’s jacketed wall enables precise heating, cooling or drying, and its open, obstruction-free interior ensures optimal hygiene and minimal product retention.
Thanks to its bottom discharge valve, the CPM achieves full product emptying, reduces manual cleaning, and minimises the risk of cross-contamination between batches. The design eliminates dead zones and allows excellent process reproducibility — ideal for demanding applications such as instant products, powder–liquid blending, or low-temperature drying under vacuum.
