Vertical Auger Diet Feeder

Spirmix Trapdoor : Mixer wagon - Diet feeder

The Spirmix diet feeders 16 – 18 m3 are equipped with vertical stepped augers that brew and aerate the mixture, they can feed about 85 to 120 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. Easy to use, the Spirmix mixer feeders are perfectly suited to rations consisting mostly of silage. To facilitate distribution, the mixture slides on a flap located under the trapdoor to offset it from the axis of the tyre. The Spirmix mixer wagons are standard equipped with the SystemX weighing system that guarantees a perfect accuracy for preparing rations.
