Vertical Auger Diet Feeder

Spirmix Conveyor :  Mixer wagon - Diet feeder

The Spirmix diet feeders 20 – 26 m3 are equipped with vertical stepped augers that brew and aerate the mixture, they can feed about 105 to 160 dairy cows per pass. The rolled tank of the mixer feeder gives various advantages, it reduces the power required for making a mixture; the flared and smooth shape makes the ration homogeneous more rapidly. The distribution by conveyor is ideal for fibrous rations. The transversal conveyor ensures regular and quick distribution to right or left regardless of the prepared ration. The width of the conveyor prevents jamming problems and gives an even spread along the feed table.  The conveyor can be fitted to the front or the rear of the machine to be able to distribute, even in dead-end corridors. The Spirmix mixer wagons are standard equipped with the SystemX weighing system that guarantees a perfect accuracy for preparing rations.
