The below video is an extract from our Mechanical and Electrical Engineering Explained Online Video Course. The following process description is based upon a ball mill used in the hard rock mining industry for liberating minerals from ore, but the operating principle for ball mills used in other industries is the same. ...
These mills use balls or beads to crush, grind, or impact materials with high kinetic energy, resulting in rapid and efficient size reduction. High-energy ball mills are commonly used for grinding hard and brittle materials, such as metals, alloys, ceramics, and minerals.
Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, …
