The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:

Ensure that the surrounding soil left in the walls of the hole is solid, leaving a 150 – 200 mm gap to allow positioning the tanks, and back-filling with sand or metal dust, stabilised with cement dust. If there is major water seepage into the hole from the surrounding soil, the site will not be suitable. Make sure tank site is drained well.
