Determining parameters of grinder rotor and its blades

The rotary crusher allows you to qualitatively grind pressed roughage. authors proposed and developed an improved technological scheme of impact equipped with two beaters for dosed transfer the grinding chamber. consists a chute, metering beaters, chopping chamber, rotor, knives, fixed exit feed bin, electric motor. Work efficiency is determined by following parameters: length, width, thickness rotor speed. purpose work substantiate parameters its knives. Analytical dependencies are obtained determine knife. Theoretical studies have established that minimum length knife should be 6.9 cm, width 50 mm, 4 mm. A model theoretical calculation probability roughage required size within limits zootechnical requirements has been obtained. Based on calculations, cutting size, depending number rotations rotors, was established.
