Weir Minerals’ mill liner lasts longer

Whilst this technology performs well in most grinding applications, many suppliers are perceived by the market to offer similar rubber compounds with no real differen- tiation. Weir Minerals identified a clear gap in the market for a rubber compound that could increase the wear life of its mill liners and outlast the rest.

Fields results show that the new Vulco ® R67 mill lining rubber compound from Weir Minerals delivers an increase in wear life of 20%. With a liner that can run significantly longer, operators will experience a measurable reduction in mill downtime, installation and mainte- nance costs. “This is a breakthrough in the indus- try; a rubber mill liner that in extensive global trials delivered on average 20% longer life than comparable compos- ite lifter bars. This means less shut- down time for maintenance, which in this highly competitive environment represents a measurable outcome to our customers’ productivity and bottom line,” states Mathias Kuhrke, Global Product Manager for Mill Lining Systems at Weir Minerals. The innovative premium rubber compound is the most wear resistant Weir Minerals has ever formulated. Operators using R67 lifter bars within their mill will not only benefit from the increase in wear life, but they will notice a measurable reduction in installation and maintenance costs as a result of a longer run schedule. Weir Minerals is an industry leader in materials technology and have been supplying the Vulco® R63 rubber compound to mill lining applications across the globe for over 50 years. The Metso Lokotrack LT200HP(TM) mobile cone crushing plant is designed for secondary and tertiary crushing operations such as produc- ing aggregates for railway ballast, road construction, asphalt and concrete fractions. Thanks to its direct v-belt drive from the gearbox, the renewed solution delivers fuel consumption savings of at least 15% compared with hydraulic-driven cone crushers. Furthermore, the LT200HP complies with European Stage V emission regulations. “Fuel consumption and efficiency are always at the top of our cus- tomers’ priority lists, and reducing

After extensive field research on the current rubber compounds available to the market, Weir Minerals expert engi- neers and material scientists devel- oped the unique patented material that forms the R67 compound. “Using our extensive in-house knowledge, experience and expertise, we were able to develop a new Weir proprietary elastomer that is able to withstand the severe abrasion typical in mill systems applications. Our Vulco R67 compound utilises new technology and chemistry in elastomer formulary which overcomes the limitations of more traditional elastomer compounds used in the market today,” states Dr. Michael Lum, Materials and Elastomer

Development Manager for Weir Minerals.

The Vulco® R67 rubber compound is visually different from others in the market place, with green capped ends on the lifter bars. “During the product development process we added a green pigmenta- tion to the formulation to visually set our lifter bars apart from the compet- itors. Now when a mill operator sees the distinct green strip on the lifter bar, they will know they have a premium product,” says Lum. l
