The mixing action is achieved by means of the counter-rotation of the paddles, which force the material to pass from one side to the other of the trough, spread it and cause in this way the homogenization and handling of material.
Watering action is realized with pressure nozzles placed in different points of the trough.
The mixing paddles can be supplied with a wear-resistant, double thick chromium plating or a tungsten carbide reinforcement on the external surface and following complete double thick chromium plating.
The double shaft mixers are available with mixing trough lengths from 2500 up to 3735 mm, paddles diameters from 420 up to 860 mm for throughputs of approx. 15–200 m3/h.
