The balance of power consumption of the process of grain grinding

The purpose of the research is to determine the power consumption of the process of grain grinding with a grinder. When conducting theoretical studies to determine the amount of energy spent on grinding grain during the operation of the grinder, the physical and mechanical properties of the grain, the parameters and mode of operation of the grinder, the energy consumption to overcome harmful resistances, to grind grain and to discard the crushed mass were taken into account. The technological scheme of the grain grinder is given. A mathematical dependence is proposed to determine the power consumption of the grain grinding process by a grinder. It has been established that the power consumption of a hammer grinder is mainly influenced by the number of hammers, the angular velocity of the hammer, the area of the front part of the hammer, the radius of the grinding chamber, and the physical and mechanical properties of the grain. As a result of the research, graphical dependences of power consumption and productivity on the number of revolutions of the hammer propeller were built.
