Cnc Machine is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier.In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
