Jan 13, 2014· Mill Lubrication System 1. OBJECTIVES: To identify the definition and importance of a hydraulic lubrication system. To be familiarized with the lubricant and equipment used in the system. To understand the process and various design of Mill lubrication system. To identify some problems encountered by the system, and formulate some recommendation to help fix the problems.
Sep 14, 2016· The semi-autogenous grinding (SAG) mill is the main production line in the concentrator plant for Kinross, which is a gold mine operation located in Minas Gerais, Brazil. Cash flow losses of more than $2 million were reported in 2013, with at least 79 events identified as lubrication failures.
higher mill speeds, and with the onset of slurry pooling at higher flow rates. To address these issues, the following criteria was followed to select suitable SAG mill liner package: • Maximise power drawn by increasing mill speed while minimising direct shell impacts • Increase SAG mill .
Figures 8 and 9 on the right show results from a gold plant's SAG mill achieved with MillStar's Segregated Ore Feed Controller combined with the Power Optimiser: • The standard deviation of the mill feed control is greatly reduced. • The cyclone feed is more stable, allowing for consistent size separation and feed to downstream processes.

8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.

SAG mill energy required according to this statement, is 2.5 times more than the Ab value to produce the same degree of particle breakage. There is a speci fi c gravity factor that affects AG/SAG power draw. The lighter material, in the 2.5 specifi c gravity (SG)
Some dry autogenous mills operating in Canada are 8.5 m in diameter and 1.5 m in length. These are known as Aerofall mills. The Cadia Hill (Australia) wet SAG mill is 12.2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.
Advanced Simulation for Semi-Autogenous Mill S ystems: A Simplified Models Approach 147 description it is necessary to consider the relationship between the feed stream and mill charge level. This relationship is known as the transport rate and is probably the least developed aspect in models proposed so far (Apelt et al., 2002 a,b).
The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen (5), which acts like a large sieve.

A parameter, R, which relates the SAG mill throughput increase and the pebble flow rate was defined to make possible this comparison. Throughput increase is defined as the difference between SACB and SAB circuit throughputs. R = throughput increase/pebble flow rate
