Weir Minerals announced the global launch of its Accumin lubricators, following international demand for the grease lubrication, which has been ensuring optimal performance for equipment such as Warman® slurry pumps since 2014.
Across more than 100 sites, the Accumin lubrication system has proven itself as an efficient method of preventing expensive bearing assembly failures. It reduces maintenance downtime and promotes safety by decreasing the amount of manual interface required for optimal equipment performance.
“At Weir Minerals, we make the market-leading slurry pump for mining applications, but we can’t always control what happens when it gets to site. Between dust, overflow and gland seal leaks, lubrication is a vital tool in the constant battle to keep machinery going,” says Michael Roinich, Accumin specialist at Weir Minerals.
According to Roinich, fitting an Accumin lubrication system prevents over and under greasing, protects equipment from bearing failures and frees up man hours for more critical tasks.
“When we offer Weir Minerals equipment with an Accumin lubrication system installed, what we’re really doing is giving that equipment its best shot at a long and productive working life,” he says.
Made in Germany, Accumin canisters are produced in 125 cm3 gas driven and 120 cm3, 250 cm3 and 500 cm3 electro-mechanically driven configurations, and can be deployed up to 5 m away from the lubrication point, allowing easy and efficient access to the mount. The electro-mechanical driven lubricator dispenses a consistent dosage of lubricant, regardless of ambient temperature. The system delivers 6 bar of operating pressure and can easily be monitored via an LCD display, flashing LED alert system and a transparent grease cartridge.
“Designed to meet the arduous demands of the mining industry, Accumin single-point lubricators set the global standard for lubricating Warman pumps and other grease-lubricated, mission-critical mining equipment supplied by Weir Minerals. We’re excited to share our market-leading, best-practice system with mines around the world who are embracing new technologies to simplify their operations,” Roinich says.
Accumin success on iron ore mine
A combination of increasing production and a change in maintenance procedures led to a pump bearing assembly fault at SIMEC Mining’s Iron Duke concentrator in South Australia. When SIMEC’s routine in-house analysis failed to detect this, Weir Minerals offered vibration analysis as part of their condition monitoring service, which operates in conjunction with the existing pump maintenance programme.
Weir Minerals identified the root cause as improper lubrication and external contamination ingress and were able to prevent a major failure of the Warman MCR 250 cyclone feed pump. Accumin 250 Lubricator units were installed to improve seal purging and prevent contamination, and a failed bearing assembly was rebuilt.
“Making the move to Accumin lubricators helped the iron ore mine save almost AU$120 000 each year in downtime reduction, pump rebuilds and bearing assembly replacements,” concludes Roinich.
Accumin lubricators are available worldwide on new pumps, through Weir Minerals’ aftermarket spare parts supply channels and via its service centre network.
