THE ASSESSMENT OF ORGANIC AND NATURAL MAGNESIUM MINERAL FERTILIZERS GRANULATION AND THE DETERMINATION OF PRODUCED PELLET PROPERTIES

摘要: The research was carried out in Aleksandras Stulginskis University with a natural magnesium mineral fertilizer – silicate Serpentine rocks that were grounded and granulated an impact granulation technology, organic cattle manure compost fertilizer, which using device horizontal granulator matrix (the diameter of pellets is 6 mm), the mixture (mixture ratio 1:1, is6 mm). There investigated estimated biometric physical-mechanical properties produced granules pellet granulometric composition indicators, moisture content, density strength (resistance to forces). Research results showed content sufficiently low, varied from 4.7 % 14.7 %, considerably high as it reached more than 1000 kg m -3 DM (dry matter). Results on resistance deformation fertilizers indicate most resistant are ones made they decompose 550.5 N force, whereas (without Serpentine) disintegrate 271.4 about twice small above mentioned one. have shown quality, these compression static force well convenient for storage, transportation mechanical spreading field.  Keywords: density, granules, fertilizers, manure, properties, serpentine, Article DOI: http://doi.org/10.15544/RD.2017.040
