ThyssenKrupp Fördertechnik (TKF) has won a contract with Guangzhou Yuanshi Investment Management to supply two continuous ship unloaders (CSUs) to China. The CSUs will go into service at the Zhujiang power generating plant on the Pearl River.
Although the gradual demise of bulk ship unloading by grab was being predicted in the 1990s for reasons of its inefficiency and environmental unacceptability, this cargo handling concept not only continues to be widely employed but is currently enjoying a renaissance thanks to recent technical advances.
Bulk terminals, unlike their container counterparts, may have the option of hydraulic or electric drives for conveyor and yard handling, but electrical drives remain the only solution for high-throughput quayside handling.
Although there will always be a place for traditional overland belt conveyors, enclosedbelt systems are increasingly being specified where environmental protection assumes high priority or where there is a need to protect material from the weather.
The physical characteristics of different bulk commodities combined with in-plant or terrain constraints determine the choice of an optimum high-capacity conveying system. Here we report on several conveyor projects, either recently commissioned or currently being installed.
Sampling of bulk solids is a vital prerequisite for most that with the new facility the group production processes, as well as providing independent evidence that the purchaser receives material to the exact specification that he has ordered.
Although the major mining groups are cutting back investments as demand slumps, there are still sufficient projects underway to maintain strong order books for stackers/ reclaimers – but next year may prove difficult.
Demand for high-capacity stackers and reclaimers, particularly for coal and iron ore, continues unabated, with the past two years proving especially fruitful for specialist suppliers of these types of machines.
