Processing machine or miller are generic terms that denote any machine that processes or grinds anything. The rice huller or husker is a machine used specifically for rice beneficiation. So they are both correct, IMO, but the latter is more specific. It depends how specific or generic the original is about the machine.

Difference? From the pictures, the rice huller/husker/miller/processing machine appears to be the same thing. Does anyone know the difference?
