Vertical Auger Diet Feeder Straw Blower

Spirmix Jet : Straw bedder wagon - Diet feeder straw blower

The Spirmix diet feeders with straw blower 12 – 14 m3 are equipped with a vertical stepped auger that brews and aerates the mixture; they can feed about 60 to 90 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. These mixer feeders with straw blower are fitted with a turbine that ensures an accurate distribution and an efficient straw blowing of the livestock buildings.

The straw blowing assembly comes from the CASTOR range, recognized for its performance and reliability. As standard the mixer wagon is equipped with a lateral chute (18m) it can be equipped with a swivelling chute (15 m right / 13 m left) or the SMART chute (distribution along the tractor / machine coupling and straw blowing up to 19 m). The Spirmix mixer feeders are standard equipped with the SystemX weighing system that guarantees a perfect accuracy for preparing rations.
