A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().

After you''ve engraved your circuit you need to cut it out from the copper clad stock somehow. So far I''ve done this by scoring and snapping the copper clad, cutting out the board with a 40tpi blade in a jigsaw, using a paper cutter and using hand written GCode for the CNC to mill out the board.
CopperCAM is an application for managing isolation engraving, drilling and cutting printedcircuit board prototypes. It does not integrate the direct drive of a CNC milling machine, but simply outputs files that can be loaded and used by external driver software, or data to be sent to the machine.
The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible. What doesn''t float is called tailings because it goes out the "tail end" of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and reused.

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.
