Page 63: Analysis Of Feed Mixture
SECTION 4 Pronar VMP-5ST | Pronar VMP-6ST 4.4 ANALYSIS OF FEED MIXTURE Proper degree of mixing and disintegrating should be checked each time before adding a next ingredient. The mixer feeder operator should take several feed samples and visually inspect the feed mixture consistency. If individual samples are similar, the fed ingredients are properly cut and mixed. - Page 64 Pronar VMP-5ST | Pronar VMP-6ST SECTION 4 mixture may stick to the auger surface. To prevent it, increase PTO speed to 540 rpm in order to remove as much feed mixture as possible from the tank. The parameters of the auger drive system are so selected that the power demand at the PTO speed of 540 rpm is the minimum to ensure proper mixing of feed ingredients.
