Apr 04, 2018 Energy Efficiency. A large metalliferrous concentrator HIGmill was equipped with the flat discs. In order to improve efficiency of the power draw and prolong the life of the discs, GrindForce rotors were installed into the mill. Immediately after the installation of the castellated rotors, a benefit in the energy efficiency was observed.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency 5 Autogenous mill. Autogenous or autogenic mills are so-called ...
When used to power semi-autogenous (SAG), ball and autogenous (AG) mills, GMDs provide improved throughput, reliability and availability at processing plants Traditional ring-geared mill drives have a ring-shaped gear that encircles the mill and drives it through one or two pinions followed by conventional motors.
The milling circuit consists of two semi-autogenous (SAG) mills, SAG 1 and SAG 2, in open circuit and a Ball Mill in closed circuit with a cluster of cyclones. The SAG and Ball mills discharge is pumped to a set of primary cyclones whose under flow reports to the Knelson concentrators for free gold recovery while the overflow is screened, conditioned and subjected to conventional
