The loading of coal poses manychallenges for the bulk materialshandling industry. Coal is loaded inmany different ways, such as intoships, trucks, stockpiles and manymore, all with a requirement ofminimizing dust emissions andproduct degradation. Thesechallenges are well known toCleveland Cascades Limited, theTeesside (UK)-based manufacturer ofbulk materials loading chutes.

Since 1992 the company has beeninvolved in the design andmanufacture of loading chutes, withits unique ‘Cascade’ system being atthe forefront of the industry. Theloading of coal seems preferredthrough the Cascade system due toits emphasis being around preventingproduct degradation and dustemissions. Loading material throughoppositely-inclined cones at lowvelocity yet high volume results in minimized dust emissions andremoves the requirement of expensive dust-extraction systems.

Coal is generally more valuable in larger lump sizes, as it hasbetter burning qualities than smaller lumps or lumps that have

suffered damage due to free-falling and smashing topieces/dust. This is where theCascade system providesextremely effective results as theproduct is supported the wholelength of the chute by oppositelyinclined cones, ensuring a softdelivery from outlet to materialpile every time.

With over 600 systemsoperating worldwide withapplications in ship, silo, road, rail& tanker loading, the company’skey to success is its provenability to provide a well-engineered solution withprofessional and committedsupport.

Cleveland Cascades Ltd hasworked with some majorcompanies on coal loadingprojects, including the IsraeliElectric Corporation, Tenova,PHB Weserhutte, FAM andPuerto de Mamonal.

Coal loading has always beena significant part of ClevelandCascades, with the companyproviding its first coal-loadingsystem in 1996; a shiploadingchute for use in South Africa.Most recently, the company hasbeen involved in coal shiploadingin particular, for use with manycompanies in South America.

T Recent coal loading projects include a project for FAM inColombia. This 18.5m-length application loads ships at up to2,750tph (tonnes per hour). This project is unique to ClevelandCascades as there was the requirement to include a trimmingspout that will achieve five metres trajectory from the centre-lineof the loading chute (see fig. 1). Another recent project for thecompany was another shiploading system, again for operation inColombia. This is a smaller system loading at 1,000tph. The chuteagain includes a trimming spout, at a standard 1.5 metretrajectory (see fig. 2).

The company has also provided conventional freefall loading

systems (see fig. 3), stockpile loading systems (see fig. 4) andVehicle loading systems to handle coal, all with the with the sameattention to detail, thorough engineering process and highstandards of quality, believing that every system produced is adirect reflection of the company and the best possible form ofadvertisement to potential new customers.

Cleveland Cascades Ltd hopes to remain at the forefront ofinnovative design within the bulk industry, taking our technologyand experience and applying it where possible to solve dust andmaterial degradation issues.

With this ethos of continual improvement and expansion,CCL hopes to further develop itself into and continue to be awell-established figure within the bulk industry.
