How Many HP To drive A Meat Grinder Smoking · That I know of hand crank grinders generally don t have bearings Therefore the rpms need to be kept low I m thinking 60 rpm max 30 45 better With gear reduction as the ratio increases so does the applied torque Therefore the starting rpm will have a lot to do the amount of reduction and that in turn will have a lot to do with HP/torque
