Effect of Varied Pulleys on A Centrifugal Palm Kernel Cracker

This paper is based on the performance evaluation of centrifugal palm kernel cracker for small, medium and large scale firms that deals with cracking nut to meet market requirement. The machine has hopper, chamber which incorporates shaft flange, outlet, electric motor, belt pulleys. was evaluated by considering time speed. modified introducing four pulleys diameters 200mm, 250mm, 300mm, 350mm, produced rotor speeds 936rpm, 749rpm, 624rpm 535rpm respectively. were then used test designed its efficiency evaluated. chamber, flap nuts stationary hard surface. operated 15hp motor. result showed highest at 936rpm 53% a taken 38sec crack effectively.
