Abstract: Advances in materials, instrumentation, monitoring techniques, process knowledge and an ever increasing demand for efficiency and conservation have opened the way to research in areas of comminution that have been overlooked or abandoned time and time again.
exploited by fully autogenous grinding, rather than semi-autogenous grinding. This also allows for crushing of the sizeable stream of silicate pebbles discharging from the autogenous mills, without risk of crusher damage through miss-directed grinding media. This way, it was believed that the primary mill throughput could be increased by about
Grinding media are of two types-steel balls and grinding rods. The size of grinding steel balls can be a diameter between 20mm and 150mm, or 1 inch to 6 inch. The size of grinding rods can come in diameter between 40mm and 120mm. Forged steel grinding balls do not lose shape or crack easily. They are durable and have great …
