Resumen

Instability of physicomechanical ore properties leads to significant variations of ore preparation including alternation of underloading and overloading modes within crushing process. To develop automatic control systems for a closed crushing/screening cycle, timely measurement of granulometric ore composition parameters is required. GRANIX videosensor was installed and tested at the Erdenet mine/mill plant for granulometric ore compo- sition visiometric control. Commercial test results suggested that relative measurement error for separate crushed ore sizes is 2,67%-7,51%. The proposed algorithm of crushing control includes measuring granulometric ore composition and power consumption of a crusher drive, controlling loading on crushing in a closed cycle and width of a crusher discharge slit. The system allows to optimize crushing by certain criteria (product yield, screening efficien- cy and circulating loading), obtain preset-size crushed product, increase crushing unit capacity and reduce specific energy consumption for the entire ore preparation process.
