Performance, which included feed water pretreatment, system configuration optimization, and pressure balancing. these improvements resulted in: o increased production rate of the system to 150% of design o system recovery rate of 90% o drop in system pressure requirements that doubled the flow rate through the system, reducing energy use

the millstar advanced control system has a comprehensive suite of control strategies that can be applied to provide an innovative control solution for almost any milling circuit configuration. the main goals are: • stabilise the mill feed. • control product quality to the downstream processes. • optimise throughput and grinding efficiency.

key words: grinding, gearless mill, ring-geared mill, variable speed drives . factors come in the evaluation of the system such as flexibility and optimization of operation, reliability and the ageing of the grinding equipment. (approx. 160 - 200rpm) connected directly to the pinions driving the ring gear or by high speed

a good advanced control system such as millstar apc can significantly increase throughput and grinding efficiency. additionally, the liner and lifter life can be extended and the percentage grinding media per ton of ore processed can be reduced. controlling the feed and discharge of a mill is mostly a stabilisation exercise.

optimization of mill performance by using online ball and pulp measurements soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. crash stops are difficult to handle. the mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.

Optimization of process parameters the samples were milled with the steel jar with 50 ml volume of the retsch pm 100 planetary ball mill (retsch pm 100 ma, retsch gmbh) combined with 0.3 mm zro 2 figure 1 beads as the grinding media. the concentrated (10% w/w) predispersions (2 g of mel suspended in 18 g of dispersant

gearless mill drives are a well established solution for grinding applications in the minerals and mining industries. the paper describes the functionality and technical features of such drive systems as well as their advantages compared to other drive solutions.

the metso outotec slurry wheel upgrade is a retrofit sealing solution for the grinding mill feed end. the existing configuration is replaced with a new and improved slurry return system featuring a unique water-wheel design that significantly improves the material containment of the feed ends.

each mill is equipped with a 2 x 8500hp dual pinion drive system. the plant was designed to process 1585 h mtpof sag feed. from startup, the mill struggled to meet the required production rates. over time, a major initiative that involved blasting and fragmentation, optimization of the sag mill in terms of discharge grates, ball size and slurry

The circuit was designed on the basis of data obtained from a consistent grinding pilot plant campaign. the ore variability was also assessed through the grinding circuit consists of a single line configured as sabc with a simulation using data from a drilling core characterization program. nominal capacity of

grinding circuit energy consumption was 6.7% lower when the ecs/processexpert system was used. by independently analysing each of the main machines, it was found that the energy consumption of the ag mill, cyclone pump and ball mill were 5.10%, 6.48% and 9.25% respectively lower when the ecs/processexpert system was controlling the grinding

the mill and the balance of material flows through the system, it is possible to identify situations when the feed to the mill and the output can be increased. increased output over extended periods of time has been observed on mills controlled by expert optimizer. • reduced power consumption. this important saving is a result of the softer
