The mill is fitted with a steel lining system with 40 mm grate apertures and 60 mm pebble ports. The make-up ball size is 125 mm. Pebbles from the SAG mill are conveyed to the HP500 pebble crusher (cone crusher), operating with a closed side setting of 12 mm. The design crusher feed rate is 150 tph or 30% of new feed to the mill.

Ball 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.
