By Dane Olson W hile new technologies in the cement and mining sectors may not be as profound or as frequent as in other industries, quarry and mine operators are focused on continuous improvement of processes and equip- ment to achieve greater capacity and improved reliability. In industries that have invested very little in equipment upgrades since the economic downturn of 2008 and 2009, modernization of existing systems to increase throughput is a focal point as market demand continues to rebound in sectors such as cement. The most common retrofits are occur- ring with bucket elevators and apron conveyors where metal chain traction elements are still being utilized in con- veying. For many years, conditions related to particle size or temperature required the use of only chains in both bucket elevators and apron conveyors. Notoriously expensive to maintain and replace, chains require continuous monitoring and must be shortened as they stretch. Knowing that anything mechanical begins wearing down as soon as it begins to operate, full system optimi- zation declines over time. A propri- etary steel cable belting solution engi- neered by BEUMER to replace chain traction elements can help systems achieve what they did when they were first installed. A steel cable reinforced belt requires a fraction of the maintenance of a chain
