The difference to the other models is that the angle of inclination of the mixing hopper is always positive. The adjustment is carried out thanks to the telescopic leg on the outlet side. The adjustment is manual for the small mixers 20, 50 and 150. It is push button controlled for the models 500, 1200 and 2500. The mixing hopper is equipped with two openings. The outlet is at the upper side. For emptying the mixing hopper the mixing screw is put into reverse motion and the mixing screw pushes the remaining product to the second opening on the lower side of the mixing hopper.
