The MD 400 Series 4500 paddle mixer utilizes a unique two-tank design to enable the continuous batching of a homogenous solution. The slurry is prepared in the upper tank where it is thoroughly mixed by the continual cutting action of the rotor blades, and is then sieved and transferred to the lower tank where it is maintained in a consistent mixed condition. The slurry can then be sucked from the lower tank by the injection pump, while a replacement batch is being prepared in the upper tank.

The superior design of the MD-400 Series 4500 paddle mixer ensures mixture consistency reducing the potential for de-mixing of components with uncontrolled and over aggressive paddle activity. The slurry is maintained in a controlled suspension ready on demand by the pump.
