CPM | conical paddle mixer

The conical paddle mixer can be used 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 important.

Typical applications

The conical paddle mixer is suitable for a wide variety of process applications, including:

Mixing of fragile powders and ‘instant’ agglomerates
Mixing of powders with liquids
Sterilisation and pasteurisation of product batches
High-temperature processing of powders and liquids
(Vacuum) drying at low temperature with liquid recovery

The mixing vessel is conical shaped and 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.

Conical paddle mixer

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

Heavy duty and smart design
Suitable for multiple processes
Minimum product distortion
Optimal temperature control
