It mainly includes crushing process control, crushing appliance fault diagnosis, and automatic distributing control. Crushing Process Control. To ensure the continuous, stable, and safe operation of the ore crushing production process, it is necessary to monitor the running state and parameters of key equipment (such as …
Mineral processing, also known as ore dressing, mineral beneficiation, or mineral engineering, is defined as the science and art of separating valuable metallic and …
Crushing and grinding is the most costly step in mineral processing because the power needed to liberate the minerals is very high. In this sense, grinding is commonly said to be the key to good mineral treatment and the major consumer of energy, accounting for up to 50% of a concentrator's energy consumption ( Table 6.3 ).
For electro-hydraulic crushing, it mainly relies on the strong shock wave generated by high current to crush the minerals and its main mode of action is pressure; for electric-dynamic crushing, the discharge channel of the current is formed inside the mineral, the discharge channel generates tension to break the mineral, and its main …
