The presentation of this work has been done on 19th June 2017 at Luleå University of Technology.

Get Pricelarger SAG mill will achieve a processing rate in the range of 100,000, to 110,000 tonnes per day, which is an increase from the 95,000 tonne per day rate projected in the Prefeasibility Study Progress Report.

Get PriceThe screen undersize is returned to the primary mill to avoid mud spills inside the plant, especially on electric equipment such as the SAG mill motors. This design allows for addition of extra magnetic separators and eventually metal detector systems electrically interlocked with the movable feed gate to the screen (or crusher).

Get Price· The SAG mill model of Napier-Munn et al. was used to describe the grinding process, along with a novel ball charge model and a mill-liner model. Using measurements of the mill charge weight and size-by-size solids discharge, Apelt et al. [26] used 29 measurements to estimate 37 states and 7 parameters with an extended Kalman filter (EKF).
