Grinders for processing mineral raw materials

The paper substantiates the importance of increasing the crop yield on cultivated areas through improving soil fertility with the use of innovative grinding equipment that enables preparing mineral materials and caked fertilizers. There is a review of advanced engineering solutions that provide the enhancement of grinding process and reduce energy consumption. The paper presents the results of evaluation of power consumption when grinding inorganic material in the mill with indifferent group that confirm the possibility of efficient use of power, which is basically costless, for improving the energy efficiency of grinding.
