The Spirmix diet feeders 27 – 46 m3 are equipped with vertical stepped augers that brew and aerate the mixture, they can feed about 140 to 285 dairy cows per pass. The rolled of the mixer feeder tank 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.
