Abstract:
The organic manure crusher was designed and constructed from locally available materials for crushing the cow dung into small size particle enough to pass through the holes of the detachable concave sieve positioned beneath the hammer assembly. The crushing process is achieved by the use of swinging hammers in beating the material fed into fine particles. Based on the power ratings and output shaft speed of the existing grinding machines in industries; it was found that the rotor shaft speed of 1500rpm is suitable to crush the cow dung. The machine was designed to be motorized and portable with overall dimensions of 790 x 400 x 1070 mm.
