1.1 PHASES OF A MINING PROJECT - ELAW

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer …

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 processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Under the low-speed circumstance, steel balls drop after rising to a certain level, with grinding as main acting force supplemented by the impact. If increasing the speed, steel balls are thrown and fallen, with impact as main acting force supplemented by grinding. At higher speed, steel balls will do centrifugal exercise instead of grinding work.
