Field of Application

Compulsory mixers (cyclone mixers) are used to mix dry, moist and wet mixtures. The main advantage is the perfect mixing of the individual components of the mixture over a short period of time (the speed of mixing is 4-5 higher compared to the normal drum mixer) which guarantees a high quality of the final mixture.

Compulsory mixers are suitable for the mixing of refractory concrete mixes that are designed for firebrick linings, for instance, in foundry furnaces, blast furnaces, heating plant boilers, coke-oven batteries and chimneys in the metallurgical and chemical industries. Compulsory mixers are also used to mix a wide range of construction materials in the construction industry, namely plastering, grout, and repair mixtures. Compulsory mixers are also suitable for the industrial mixing of mixtures during which material is processed by individual batches.

Working Principle

Compulsory Mixer - standard construction with wheels

Compulsory mixers work on the principle of mixing arms which rotate at a very high speed around the inner axis of the static mixing tank. Mixing is done by several arms which ensure that that the mixture is wiped off the sides and the bottom of the mixing tank. The mixing arms can be adjusted sideways and in height and they can be equipped with rubber spatulas.

Depending on the type of mixed compound, mixers can be fitted with several kinds of stirrers

The mixer models designed for the mixing of abrasive materials have their mixing drum provided – up to their utility mixing height – with a replaceable lining made of standard or abrasion-proof material. Alternatively, the mixing drum itself can be made of abrasion-proof material.

They are offered two basic mixer types, each characterized with a different construction:

  • standard construction with wheels
  • heavy-duty construction (H series)

Mixture is filled via a screen in the cover of the mixer. The screen is equipped with a separating comb for bagged mixtures. The construction of the cover prevents any spillage of material over the sides of the tank. If need be, the mixer can be provided with covering sheet metal preventing the leak of thinner or dusty mixtures. The prepared material is released by turning the movable segment on the bottom of the tank.

Compulsory Mixer - heavy-duty construction (H series)

The mixing tank is firmly connected to the stand that can be equipped – in case of models M 50 – M 250 – with wheels. The M 50 – M 180 mixer models are fitted with height adjustable posts allowing for the variable height of discharging.

The drive of the mixing arms is ensured by a low-maintenance, worm or front-cone electric gear unit. The smallest types of mixers (M 50/230V, M 50/400V and M 80/230V) are fitted with a maintenance-free electric gear unit. Models with a motor output of 5.5 kW and higher are equipped with a soft starter that facilitates a continuous blade startup.

To ensure maximum safety of the service personnel, enhanced safety features have been employed such as the no-voltage trigger and a terminal switch switching off the engine when the cover of the mixer is opened.
