Toe angle measurement for SAG mill control at

Typically a SAG mill weight measurement by either bearing pressure transducers or load cells is used as an inferred measurement of volumetric filling To maintain volumetric filling within a set operating range the SAG weight setpoint use for process control requires regular review due to changes in SAG mill charge density (rock:ball ratio) and the wearing of mill liners At Lihir Gold Mine

Ignition of Hydraulic Fluid Sprays by Open Flames and Hot

Cochrans Mill Road Pittsburgh PA 15236 USA Abstract A study of the ignition of non-fire-resistant hydraulic fluid sprays was conducted by the National Institute for Occupational Safety and Health Both an open flame and a hot steel surface were used as the external heat sources With the open flame as the heat source the minimum oil temperature and minimum spray nozzle pressure that

Getchell Mine Development New Mill
