Crusher Management System
The new Jaques Crusher Management System has been developed to provide the optimum control and productivity for hydraulic shaft supported cone and gyratory crushers. The Jaques Crusher Management System [CMS] is a micro-processor based control and regulation system for crushers. The CMS automatically controls the Closed Side Setting [CSS] of the crusher to maintain high productivity without the need for continuous operator intervention. Hydraulic pressure and drive motor load are monitored, and the CSS automatically adjusted to prevent overload and damage to the crusher and drive motor. Other crushing system inputs are also monitored, triggering a warning or shutdown situation as necessary. The CMS incorporates a data logger which enables historical analysis of crushing performance and operation. CSS, drive currents, pressures and temperatures are all data logged. Three serial ports are provided to allow remote operation and monitoring of the crusher by a remote computer or PLC. Modem support is provided for remote access, enabling rapid diagnostics by service personnel. An easy-to-use Windows (GUI) program allows both live and historical trending through a personal computer.
CSS Monitoring
The CMS ensures that the crusher is operating at its maximum crushing pressure and power in relation to the set CSS providing improved productivity. Should the recommended maximum crushing pressure or power be exceeded, the CMS will automatically adjust the setting to suit the limits. The crusher will always work towards the CSS you have set but will not close below the nominated minimum CSS. Improved screen efficiency (reduced recirculating load) and wear life of the manganese are some of the benefits of the crusher operating efficiently.
Extra Protection
Pressure spikes often caused by poor feed conditions, e.g. segregation, etc. is detected and the crusher loading is managed to reduce the effects of these damaging shock loads.
Automatic Wear Adjustment
The CMS trends the manganese wear taking place during actual operating hours. Adjustment of the mantle position is then made automatically to maintain the desired closed side setting.
