Theoretical determination of the speed and number of revolutions of the grain grinder hammer propeller

A mini grain grinder device was created for small farms, which is used to prepare feed by grinding grains. The main working organ of the a propeller with hammer, and grains during work process depends on rotation speed hammer number revolutions propeller. Because when rotates, attached it must be sufficient crush With this in mind, theoretical studies were conducted rotations needed grind determined. According research, should at least 40.2 m/s crushing device, ensured reaches 1785 rev/min radius r = 0.215 m. For rapid nutritious machine, higher than rev/min.
