The circuit comprises a SAG mill, 12 m diameter by m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bidirectional rotational capacity. (Reversing direction evens out wear on liners with symmetrical profile and prolongs operating time.)

Fully autogenous circuits are attractive due to the elimination of steel media costs. Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 40%. Autogenous milling is typically practiced in association with

A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place. The basic principle of mill machine is that when any

SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your operation. The
