Mining 101
Mining - the accessing/removal of minerals from the earth - is a complicated operation requiring methods tailored to each ore deposit. Open pit mining is used to mine ore deposits close to the surface. Huge shovels and trucks deliver a steady supply of ore to the mill. Underground mining requires more intricate methods to access/remove ore.
Safe, Reliable and Efficient Crushing and Grinding in Mining Operations
In mining operations, the comminution process reduces the mined solid materials through crushing, grinding and other means. SAG and Ball mills are one of the most critical pieces of equipment for the process. Mining operators need to optimize grinding mill performance, and reliability to ensure tight shutoff.
