CONTROL OF CRUSHING CIRCUITS WITH VARIABLE

2010-7-14  control is the feed setting. However, nowadays is common to flnd in many crushing plants variable speed drives driving conveyor belts, this extra degree of freedom provides the opportunity to improve the speed of response of the control system. This work proposes a simple but efiective control structure to achieve this objective.

Mass balance control of crushing circuits Chalmers

This paper describes a novel circuit-wide control scheme that addresses the challenging problem of mass balance control of crushing circuits. The control objective is to ensure 100% utilization at the circuit bottleneck and hence push the realized performance towards the theoretical maximum. The present control problem is challenging due to long transport delays, complex circuit layout, under
