  • Page 22: Environmental Hazards

    Pronar VMP-5S VMP-6S SECTION 1 1.6 ENVIRONMENTAL HAZARDS A hydraulic or gear oil leak constitutes a direct threat to the natural environment owing to its limited biodegradability. The negligible solubility of hydraulic oil in water does not cause extreme toxicity of organisms living in the aquatic environment. The formation of a film of oil on the water may be the direct cause of physical action on organism, perhaps causing change of oxygen values in the water because of lack of direct contact of air with the water.

  • Page 63: Analysis Of Feed Mixture

    SECTION 4 Pronar VMP-5S VMP-6S 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-5S VMP-6S SECTION 4 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. These parameters make it also possible to thoroughly empty the tank at the final stage of the feeding process.

  • Page 65: Adjustment Of Disintegrating Blades

    SECTION 4 Pronar VMP-5S VMP-6S 4.6 ADJUSTMENT OF DISINTEGRATING BLADES Disintegrating blades (1) must be slid into the tank in order to disintegrate light and dry materials - figure (4.4). Otherwise, the feed charge will rotate with the same speed as the auger.

  • Page 66: Cleaning

    Pronar VMP-5S VMP-6S SECTION 4 ATTENTION The counter blades may be adjusted only when the auger mixer is not rotating. 4.7 CLEANING Remove the remains of feed from the mixer feeder after finished feed dispensing.
