Abstract
To reduce grain excretion-a serious problem when feeding milk and beef cattle whole crop rice silage-a rice silage crusher was developed that applies shearing forces to exfoliate chaff or crush paddy itself using two crushing rollers turning in opposite directions with V-shaped ditches around their surfaces. Using this system, the rice grain chaff exfoliation/crushing rate reached 80%, processing efficiency was 1.1t/h, and the power required could be reduced to 0.3 to 0.4kW with the rotating speed ratio between the two rollers set to 10% and the circumferential speed set to 0.2m/s.
