Double Shaft Paddle Mixers

The Ottevanger double shaft paddle mixers, type DPMA, realizes high mixing capacity with a relative small mixer content. The double shaft paddle mixer DPMA has a mixing time, depending on the product type and quantity, from 30 to 60 seconds. The mixers are available with capacities from 500 to 20.000 liters. The mixing accuracy meets the very stringent requirements, while damage to products is prevented because of extra wide bomb doors. This ensures a residue and dust free design, due to unique sealing principle. The success of this fast mixing principle is a result of the fluidized zone, in which the particles have a complete freedom of movement. Therefore they are able to mix themselves homogeneously in a state of weightlessness.

The Ottevanger paddle mixers are designed for mixing dry powders and granulates irrespective of their bulk density or shape. Liquids can be added during the mixing process.
