0

Batch mixers of the construction series MAH and BWM are discontinuous mixers used for homogenising raw materials and the storage of non-freeflowing products. They are supplied as single-shaft or twin-shaft mixers.

  • The contents of the batch mixer is indicated in litres of useful contents,
  • e.g. 1,000 l contents in kg = useful contents x bulk density
  • e.g. 1,000 l x 0.5 t/m3 = 500 kg

  • Minimum 20 %
  • Maximum 110 %
  • The useful contents of a mixer is abt. 70 - 80 % of the gross contents.

Bulk density of the individual components:

  • Compound feed: 0.35 - 0.7 t/m3
  • Minerals: 0.6 - 0.9 t/m3
  • Individual components: 0.1 - 0.9 t/m3
  • Particle size of the components:100 μm - 4 mm ground

Field of Application

  • Mixers of the construction series MAH and BWM are discontinuous mixers.
  • They are used as individual machines or as batch mixers within a plant.
  • Liquid addition is possible to a certain limit.

Possible Applications

  • Homogenizing of different raw materials
  • Storage of non-free-flowing products (prebin;
