Mineral processing

Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size.

What is Milling? Climb vs. Conventional Milling Process

You generally use the up-milling process for rough milling and on machines that are sturdy and can withstand the cutting forces. In climb milling (down-milling), the cutting forces push the work-piece downwards and this helps in milling thin work-pieces and also results in good surface finish. However, Sudden and maximum load on your …
