Process. 44-45 (1996) 187-195 Cinding of mixture under mild condition for mechanochemical complexation Mamoru Senna Faculty of Science and Technology, Keio University Hiyoshi, Yokohama 223, Japan Abstract In contrast to the development of grinding equipment toward higher energy density for the purpose of finest comminutionSolid-state mechanochemical activation of clay,the mineral structure interact more thoroughly with phosphate than potassium or ammonium. Nevertheless, in general, all of the nutrients were released slowly. K EYWORDS : Mechanochemical activation, mineral fertilizers, clayMechanochemical activation of minerals on the,Since the effects detected in H samples are only due to the mechanochemical activation, they present d 50 within the range of 4–6 μm for the H5–H20 samples. This relatively high size is due to the binding effect caused by this mill, restraining the grinding process as regards the obtention of thinner sizes.
