Twin Shaft Mixer / Pugmill

CMQ’s unique design of the Twin Shaft Mixer gives a stream of mixed product based on infeed product weight. Material is fed in to the pugmill at the opposite end to the drive allowing easy and full access for inspection and maintenance to the electric motor, gearbox and hydraulic pack. The powerful twin-shaft mixing action transforms the raw material into a continuous stream of product.

The steel case mixer has top access on either side for inspection and cleaning. Hydraulically operated bottom radial doors open for cleaning and exposure of the total mixing chamber. There is no case build up because of this unique radial door design. A poly lining is attached to the incoming product end wall eliminating any build up on this face.

Technical Data

The number and configuration of mixing paddles is varied to suit different applications. For back fill paste mixers, a weir is added to the mixing chamber. This weir retains product within the mixer for a longer period ensuring thorough mixing of paste.


CMQ has a unique mixing shaft design that allows for the quick removal of the two mixing shafts for maintenance or the removal of the mixing chamber and drive section independently.
