  AMIT 135: Lesson 6 Grinding Circuit Mining Mill

  Explain typical flowsheets of grinding circuits involving single or combination of equipment; Reading amp; Lecture. Size reduction by crushing has a size limitation for the final products. If further reduction is required, below 5 20mm, grinding processes should be used.

  Maximising grinding mill efficiency with

  Many issues and challenges are faced in the efficient control of the grinding circuit, whether it is a ball or rod mill, a semiautogenous grinding (SAG) mill, or an autogenous grinding (AG) mill. From a physical standpoint, an operator must contend with several types of

  Instrumentation and control of a continuous SAG

  #0183;#32;The control loops illustrated in Fig. 9 have been extensively employed in grinding tests at UBC with substantial success, although alternative control algorithms may be employed. For example, the circuit could be controlled to a power draw setpoint (Mular, 1986) via a cascade arrangement as shown in Fig. 10.

  Throughput optimisation in milling circuits

  Each milling circuit is unique, and as such the goals and most optimal control strategy might differ for individual cases. Process IQ is an expert in implementing control systems for SAG and Ball milling circuits, making use of advanced stabilisation and optimisation strategies developed by Mintek.
