The 3,500 t Rolls-Royce ship loader at LKAB's iron ore terminal, Luleå, at the northern end of the Baltic Sea

Infrastructure is often required, to a greater or lesser extent, for new mine projects and this usually requires a great deal of investment in bulk materials handling. Recently, the major mining projects of the world have mainly been in less developed countries and have often required considerable bulk handling systems and associated port facilities to ship the mined products. For example, the Antamina copper-zinc mine in Peru is one of the biggest projects anywhere in the world. Infrastructure development as part of the project is likely to include 60 km of road; perhaps as much as 230 km ofslurry pipeline; 50 km of power lines; tailings and waste disposal facilities; and a port from which to ship concentrate. Indeed, new copper mines in the Andes have required the mining industry to establish a number of new port facilities up and down the west coast of Latin America, such as that for Collahuasi noted below.

Bulk shipping is often a requirement for mined products, whether it be, for example, the coal that is shipped around the US along its inland waterways or products that are shipped on the high seas, such as iron ore, phosphates or, coal, the traded commodity that accounts for the largest tonnage of international shipping.

Coal, like any other shipped product of course, requires both loading and unloading. For example, Alstom is supplying a coal-handling system to the port of Tianjin in China, under contract to the China National Import and Export Corp and the Tianjin Harbour Construction Co. for Phase 1 of the new Tianjin Port Coal Export terminal. The

order is valued at some $50 million. Equipment for train unloading, stockyard stacking and reclaiming and ship loading is being manufactured at Alstom Automation based in Leicester in the UK. Phase 1 is scheduled to enter operation in the year 2000 and willhave an annual capacity of 10 Mt. Handling capacity could rise to 20 Mt/y if the client decides to proceed with the second phase of the project.

Tianjin is the second largest man-made port in China and is the nearest to Beijing. It handles some 70 Mt of bulk material, containers and other cargo a year, of which about 24 Mt is coal for shipment to other parts of China or for export.

An example on the receiving end is the OBA Group's OBA 2002 extension project in the Netherlands. As part of this, Stork RMO was awarded a contract for the design and turnkey supply of a coal handling system. Under Phase 1A, this includes a stockpile capacity of 550,000 t (to reach 800,000 t capacity eventually) which can be built up by conveyors and a slewing/travelling stacker with an overall capacity of 4,125 t/h. The stacking conveyor, between the quay and the stockpile, is 444 m long (and will be up to 800 m long).

Ship loading

Protection of the environment is a major concern in ship loading. Marine terminal operators are becoming more concerned about minimising spillage and dust pollution. In addition, the elimination of these wastes reduces their costs and increases their profits. The copper export terminal for Cia Minera Doña Inés de Collahuasi ( , March 1999, pp.122-126) at Caleta Patache is designed to export up to 1 Mt/y of copper concentrate per year. The port site is located in the First Region of Chile, 65 km southof Iquique, and the area is characterised by extremely arid conditions and has a coastal environment. The shiploader was designed with environmental protection as a priority.

MM

The mandate for Krupp Canada's eco shiploader was not just to minimise copperconcentrate spillage, but to totally eliminate it. The bottom line was that if there were any spillage into the ocean the project would not proceed. The original shiploader design, following a traditional layout, was approved, however, there were questions as to the 100% efficiency of the spillage protection system. As a result, the shiploader was re-designed, at a higher cost, but with complete protection to the environment.

The 675 t stacker supplied by Stork RMO for OBA Group's recent project to increase coal handling and storage capacity has a reach of 60 m. Its slewing range is 300° and luffing is 0° up to +16° and operation is normally automatic.

The boom is a critical element of a shiploader's design as it must reach across the ship and over the hatch. Its specifications, including reach, weight and construction details, determine the mechanical and structural requirements of every other part of the shiploader. Consequently its weight is very critical to the cost effectiveness of the design of the entire bulk materials handling system. Due to this consideration conventional shiploader design practice is to arrange the cantilevered booms as lightweight structural lattice beams.

A significant problem with conveying loose granular materials, such as copper



concentrate, along the exposed length of the boom's conveyor belt is that the material is exposed to the environment. This renders it vulnerable to wind disturbance and spillage. In addition, if the copper concentrate on the conveyor belt has been disturbed by the wind the conveyor will no longer be loaded uniformly, possibly resulting in further spillage along the length of the belt. Thus the importance of a protected enclosure for the conveyor belt in the ship loading boom.

To accomplish total elimination of dust to the environment Krupp Canada designed a totally enclosed tubular shaped boom, which also acts as a structural member, for this shiploader. Within this enclosed boom several features ensure total environmental protection. There is a dust collection system at the transfer from the feed conveyor to the shiploader conveyor. The lower portion of the transfer chute is designed to discharge the material well within the protection of the tubular enclosure and between the loading skirts of the shiploader conveyor. The loading skirts were designed to guide the concentrate centrally onto the conveyor without spillage and a minimum of fugitive dust.

In addition, during the maintenance between loading vessels, an industrial vacuuming system provides cleans up any spillage within the gallery. Moisture means the product has an undesirable adhesive nature, therefore dry vacuuming was chosen rather than water clean up.

The luffing action of the boom is used to insert the chute into the ship's hold below the hatch so that the flow of copper concentrate from the chute is protected from the wind. A bulldozer spreads the product in the ship's hold. A debris tray under the bulldozer is integrated into the spreader system to prevent spillage into the ocean when hoisting the dozer into the hold.

Included in the design are stringent specifications for seismic control in order to maintain environmental protection in the event of an earthquake. These specifications are probably the severest in the world.

Sandwell Engineering had the design-build contract with Collahuasi, and subsequently subcontracted the shiploader to Krupp Canada. Sandwell provided the technical specifications and also assisted Krupp Canada during the shiploader design, fabrication and shipping. The shiploader was erected and commissioned by Sandwell with Krupp's assistance.

For complete elimination of dust loss to the environment, Krupp Canada

designed a totally enclosed tubular shaped boom for Collahuasi's copper

concentrate ship loader.

More copper concentrate

Sandwell has considerable experience with copper concentrate. Minera Alumbrera'sexport terminal at Rosario, Argentina, for example, has a throughput of 800,000 t/y, designed for Panamax cargo vessels. In association with Fluor Daniel Argentina, project manager, Sandwell provided both preliminary and detailed design, construction supervision for the marine structures, a ship loading system evaluation and



development of the shiploader specifications.

In Chile, at Coloso, severe seismic requirements were a factor in the design of Minera Escondida's shiploader and marine facilities. As a sub-consultant to Fluor Daniel, Sandwell provided conceptual and detailed design for the conveyor and loadout systems, a 1,500 t/h shiploader and associated port facilities.

Sandwell also has considerable experience in coal. For instance, Ridley Terminals' 12 Mt/y Prince Rupert shipping terminal in northern B.C., Canada, features a train unloading system with thaw shed, frozen-coal handling equipment and dust extraction and collection systems; two 6,000 t/h stacker/reclaimers; a 2,000 t capacity surge bin; dual quadrant shiploaders; and a computer-based terminal operations management system. Sandwell provided full EPCM services including design, procurement, construction management and commissioning.

In the short time they have been available, Cleveland Cascade chutes have proven popular and are now operating in Ireland, Germany, Greece, Korea, South Africa, Spain, the UK, Ukraine and the US, where they are handling diverse products that include alumina, bentonite, china clay, coal, coke, perlite, potash, salt and soda ash. The chute is a bulk materials loading system that considerably reduces dust emissions without recourse to dust extraction systems. Cleveland Cascade provides design services and custom makes all chutes to suit each specific application. Applications covered include ship loading, silo filling, conveyor to conveyor transfer and vehicle loading. The largest capacity chute for ship and silo loading can handle rates of approximately 5,000 m /h.3

One of the latest installations is in Israel where Rotem Amfert Negev, the large phosphate division of Israeli Chemicals, at its export terminal at the Port of Ashdod, is using one to load vessels with highly dusty phosphate. The cones of the 19.5 m long 'dustless' chute are fitted with ultra high molecular weight polyethylene (UHMW) liners. Further enhancements include a speed reducer, to further control material flow, and a material detection system which automatically raises the chute to prevent blockages. Another ship loading chute was recently installed in Jamaica to handle alumina, whichis a very problematic material to load. Another chute recently delivered was for loading lead and zinc concentrate at the port of Cork in Ireland.

Another specialist product is BMH Marine's Siwertell pocket belt ship unloader. This is designed to handle heavy, abrasive and coarse materials such as iron ore, cement clinker and aggregates, as well as coal in very large volumes, at reduced power requirements and increased unloading rates. It combines the well proven Siwertell screw technology with a state-of-the-art pocket belt of Svedala Flexowell Pocketlift design. Its flexible arm system and slewing turret enable good reach in the ship's hold. Other superior features are the enclosed conveying line, the digging ability, the small size, the light weight and the low operating and maintenance costs, according to BMHMarine

The pocket belt Svedala includes two load-carrying steel cord belts connected by triangular bars and running over twin wheel pulleys. Rubber pockets are attached to the bars between the two belts. The material picked up in the transfer device is carried by the pocket belt, which runs in a loop through the vertical/horizontal arm system to the slewing turret and back again. The pockets are discharged in the slewing turret through a chute onto a belt conveyor for transport to receiving facilities on shore.

The Cleveland Cascade chute has been successful in handling the loading of such difficult materials as

phosphate and alumina.



Arctic loading

A good example of Rolls-Royce Materials Handling's particular expertise in providing solutions to customers' unusual requirements is the 3,500 t ship loader Rolls-Royce supplied to LKAB's iron ore terminal at Luleå at the northern end of the Baltic Sea. Pelletised iron ore is railed from the mine at Kiruna to Luleå from where it is exported, mainly by barge, to Germany, Finland and the Netherlands. To meet the demanding requirements of the location, Rolls-Royce designed a radial ship loader to fill the barges.

The system uses computer-controlled technology to operate the ship loader and monitor the loading of the barges. The co-ordinates are fed into the computer and the automatic loader takes over - there is an operator for security reasons. Rolls-Royce claims this was the first time a completely automated ship loader had been designed, and it was the forerunner of a new generation of intelligent devices.

The barges have to cut a path through seas that are frozen for 40% of the year. Thus, the iron ore has to be very evenly distributed throughout the vessel to maintain stability. In the past, this had been achieved using a conventional ship loader with four or five labourers levelling the load manually. Rolls-Royce developed an automatic system to achieve the same result, not only increasing safety but also the reliability of the operation. The loader works to an accuracy of ±250 mm.

Loading out

Early this year, Bateman Materials Handling (BMH) handed over to Portnet in South Africa a new load-out station and Elbram train mover at the port of Richards Bay. A specific feature is its ability to load out seven very different types of material, including coking coal, fertilisers, sulphur and potash, with bulk densities ranging from 0.7 to 1.4 g/ml. When changing materials, all parts of the system in contact with the products are washed down throughly to minimise contamination.

The station is also able to recognise and load trains composed of wagons of different sizes, from 30-50 t capacity, randomly placed along the train. Its control system features a learning capability which has now been developed to a point that enables it to load trains extremely accurately. The Elbram train mover ensures that trains move through the station at a controlled and constant speed to obtain the best load-out performance. A special Portnet requirement was that the speed of these units be infinitely variable between 3 and 14 km/h, to handle the variety of products passing through the station. They also have a shunting capability in both directions using the wheel drive mode only.

Another recent project completed by BMH is the rapid coal loadout station at Moranbah North mine in Queensland, Australia. It comprises a 600 t surge bin, an 85 t weigh flask and a certifiable check weigh system operated via a SCADA system. It accurately loads trains of up to 102 wagons at an average rate of 4,500 t/h. The trains are made up of randomly placed bottom-dump wagons with capacities between 50 and 81 t.

controlled speed from Portnet's new load-out station at the port of Richards Bay. Coking coal is pouring out of the chute into the train's first rail car.

Refurbished equipment

Upgrading existing equipment can be a viable solution for materials handling problems and this is a cost-effective service that Rolls-Royce and others offer. Renewing the worn-out parts on equipment is an obvious solution, but a lot more can be achieved by re-engineering the entire electrical control system, for example. This immediately increases the equipment's speed and future reliability.

Major structural changes can also be made. It is a demanding process but new technologies and new steel qualities can make great improvements to the performance of old equipment.

Similarly, although maintenance is often a relatively small part of an organisation's turnover, it can have a significant effect on operational efficiency and management time. Rolls-Royce maintains the equipment in a number of ports worldwide and reports that: "By outsourcing facility maintenance, companies can concentrate on their own core business and benefit from improvement in operating efficiency and reliability of equipment. After upgrade operations, and well run facility maintenance, an old port can achieve the performance of a new one."

Schade supplies complete coal storage yard systems. Its products include stackers, stacker- reclaimers, cantilever scraper reclaimers, portal scraper reclaimers, bridge scraper reclaimers and portal bridge scraper reclaimers. Schade reports that the latter, of which there is an example in the system shown here, combine the best homogenisation characteristics by reclaiming from the front slope of the stockpile from as many blending beds as required with the facility to reclaim frozen, consolidated or fire hazard stockpilesat the side slope.

Like Rolls-Royce, Alstom stresses that as well as supplying new plant, it provides refurbishment and upgrade services to existing plant.

Storage

Temcor, which claims to be the world's largest aluminum dome builder, has completed construction on a 70 m aluminum dome for the Cerro Vanguardia mine in Argentina ( , August 1998, p.57). The 13,000 t capacity dome is watertight to protect ore containing gold and silver ore from being leached and also prevents dust emissions to

MM



the environment. The facility was specified as a dome structure to accommodate the Krupp stacker/reclaimer system. All Temcor aluminum domes are custom-designed and, the company claims, they can accommodate virtually any special equipment.

Temcor's patented centre tower construction process was used because it allowsspeedier erection with a smaller crew. Safety on the construction site was of primary concern to Flour Daniel Argentina/SADE, the general contractor for the project, and this construction process keeps workers on the ground. In the Temcor construction process, the dome is erected from the centre, outward to the perimeter using a centre erection tower. Workers assemble the frame of the dome on the ground, lifting the dome up as each strut ring is completed. On average, a dome is assembled with one-third the man hours when compared to a conventional construction system. The mine's remote location dictated that the dome be manufactured off-site and assembled in place, with a minimum of heavy equipment - a Temcor specialty.

Svedala BMH was recently awarded a contract for a new 210 Kip rack and pinion train positioner for Kinder Morgan Bulk Terminals in Cora, Illinois, US. It has been designed to handle 150-car unit trains with distributed power.

The maintenance-free aspects of an all-aluminum dome were important in the decision to purchase this means of storage. The dome has a matte finish on all exterior surfaces, and was designed to include two dormers, each with 4.9 x 5.5 m motor-operated truck doors and a man door. Additionally, the dome was engineered to withstand a heavy snow load and winds up to 190 km/h. *
