Incredible mixing efficiency with the Cormall Multimix - supplied by ABC Hansen Africa.
Raw materials are fed into the bottom of the mixer, and are moved by two large diameter auger screws to the high end of the mixer. The auger screws run in opposite directions, with diverter plates at the top, which pushed the mixed material into a molehill at the top, and then the feed falls back to the bottom by gravity once the angle of repose is exceeded.
The blending of the raw ingredients are actually performed in the molehill and tumbling action into the mixer.
The mixer is first filled with low volume product, such as concentrates and grains,, and then the large volume product is added (such as grass, straw, silage) - this ensures that the low volume materials are evenly mixed through the batch.
This mixing method has proven itself over many years, and has beaten competing designs and machines in various tests - both in mix homogeneity and feed structure.
The inclined blending angle has the effect of low energy demand, as well as soft handling of the raw ingredients, and prevents clumping of material.
While there is no specific research on how softly materials should be handled, there is a likely connection between electrical power use, and clumping in the final product.
