At the Lihir Gold Mine, the plant was utilizing mill's bearing pressure to calculate load measurement for the SAG mill in HGO1. The use of SAG mill weight for process control is additionally complicated at Lihir by compromised and suddenly drifting load cell and bearing pressure measurements on two of the process plant's three SAG mills.
This provides live remote monitoring of the thickness of liners in both SAG and Ball mills. By extending the bolt heads and inserting the Sentinel technology into standard steel liner bolts, the extended head of the eBolt wears down as the liner wears, and reports predetermined wear events while the mill .

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
The U.S. mining industry operates approximately 80 semi-autogenesis grinding mills (SAG) throughout the United States. Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills.
@article{osti_276693, title = {Fluid mechanics of slurry flow through the grinding media in ball mills}, author = {Songfack, P.K. and Rajamani, R.K.}, abstractNote = {The slurry transport within the ball mill greatly influences the mill holdup, residence time, breakage rate, and hence the power draw and the particle size distribution of the mill product.
Ball Mill Design Parameters. Size rated as diameter x length. Feed System. One hopper feed; Diameter 40 – 100 cm at 30° to 60° Top of feed hopper at least 1.5 meter above the center line of the mill.
Although a SAG mill is chosen as the case study in this work, it can be easily used for other types of tumbling mills such as ball mills. With ball mills, the selection function or breakage rate is less affected by mill holdup and therefore a constant selection function like what is used in this work can be used.
SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
the mill is used primarily to lift the load (medium and charge).
