Stockpiling, reclaiming, truck unloading and link conveyors
Typical operations in either developing a green-field site or upgrading a current stockyard operation would use a stacker/ reclaimer system for all their needs in terms of stockpiling and reclaiming of the bulk material. There are many manufacturers of stacker/reclaiming systems worldwide, with varying associated capital costs depending on the customer’s requirements.

Fighting dust with technology
Ports and harbors around the world have a growing need for high capacity terminal equipment due to the increased volume of world trade, and larger container ships and barges. Increased competition and infrastructural improvements bring constant need for innovative solutions and more than ever it is of significant importance to base decisions on thorough consideration when it comes to long-term investments in installations and equipment.

The cost and value of high angle conveying
The rationalization of sandwich belt high angle conveyor technology is fundamental to the long-term technological and economic success of high volume steep and vertical conveying. The introduction of this writing briefly retraces the development of sandwich belt high angle and vertical conveyors and cites the common denominators for success.

Long reach, low fuel: the continuous improvement of floating grab cranes
Efficiency is the key for harbor cranes in modern times. Faster, greater capacity, longer reaches, heaver loads, fuel efficiency, low emissions and many other aspects determine the applicability of the harbor crane of the future. These factors formed the basis for the design of the Lemniscate-type crane, developed for high efficiency bulk handling. The continuous development of mater ials and technology offers the opportunity for continuous improvement. In 2005 NKM Noell reentered the harbor crane market with the innovative new design of the traditional Lemniscate-type crane.

The transhipment solution: Overcoming constraints in port logistics in developing countries
In January this year Coeclerici Logistics successfully launched Bulk Zambesi, a 55,000 DWT transhipper vessel of last generation. The vessel, which is the first of two units, will start operations in Beira, Mozambique in July 2011. The second transhipper named Bulk Limpopo will be operative in the first half of 2012.

Maximum capacity, minimum fuss
At the Rugeley coal-fired power station in Staffordshire, England, the two existing coal-fired boilers 6 and 7 of 500 MW each were equipped with a flue gas cleaning plant. Plant and materials engineering firm Arthur Loibl GmbH supplied and installed the materials handling equipment for receiving limestone and the transportation of Flue Gas Desulfurization (FGD) gypsum.

Air cannons hammer preheater build-up at Ash Grove Nebraska cement plant
Efficient material flow is a critical element of dry-process cement manufacturing, and accumulation or blockages can take a big bite out of a plant’s profitability. Hang-ups in storage systems and accumulations in process vessels can choke material flow, while bottlenecks create costly reductions in equipment and process performance. Poor material flow raises maintenance expenses and drags profits down. If they become severe, flow problems can bring production to a complete stop. Although many plants still use manual techniques to remove build-up, the cost of labor and periodic shutdowns has led some producers to investigate more effective methods for dealing with this inevitable maintenance.
