In recent years, China has carried out automation research on some new crushers and traditional crushing processes, equipped with some detection and control instruments, and developed control systems. However, it is worth noting that the existing crushers in China's mines are mostly old equipment in the 1960s and 1970s and have always played an important role in production. Automated transformation of these old equipment to achieve automatic control has broad prospects in the mine: This is because the control and operation of the domestic crusher is almost entirely carried out manually, and there are many unsatisfactory conditions in production and use.
At present, the control of the crushing process is mainly to ensure the production safety and realize the sequential control and interlock control of the crushing equipment. The crushing operation process is relatively simple, but there are still many difficulties in realizing automatic automatic control. The main performances are as follows: (1) Some of the crushing processes are not continuously realized, and mechanical and artificial work are combined. (2) Removal of iron from crushing operations often requires frequent shutdowns for manual operation. Therefore, the automation of the crushing process is conditional. There are not many reports on the current crushing mine automation in China, but there are many successful cases.
(2) Content of crushing control system
The crushing operation is the first process of the ore dressing operation, and whether the process can stabilize the normal work directly affects the subsequent operations. The crushing automation control system implements the analysis and alarm of the safe working state of the crusher through the detection of oil temperature and oil pressure; through the detection and analysis of the crusher load, the crusher optimizes the control of the mine; The detection of the position and the analysis of the capacity of each crusher implements the automatic fabric and crusher load optimization balance control; in addition, it also controls the deviation and slip of the main belt, and implements logical interlocking and protection control for related equipment. Ensure the entire system is safe, stable and efficient.
