The SAG mill design is based on Outotec's proprietary grinding mill technology, developed over decades for maximum reliability and performance. The mill will be operated as a single stage SAG mill (primary and secondary duty combined) with very high throughput made possible by the use of Outotec's patented Turbo Pulp Lifter (TPL(TM)) Technology.
Low capital investment alternatives such as the optimisation of the SAG mills lifter/liner design, pulp lifters, ball charge level and ball size were studied in the SAG mill circuit as well as an ...
