Is your silo due for a check-up?30 May 2016, Published under Cement NewsThe future of the cement industry depends on the storage of bulk materials – from the quarry and raw materials, blended raw meal, clinker, through to finished cement. Like other parts of the cement plant, such as conveyors and crushers, storage structures need to be maintained to deliver optimum performance. By Gerard Lynskey, SSI Consulting, USA. Silo inspections and maintenance are essential for cement producers and can provide valuable information towards planning The Flor... |
Modular thinking04 May 2016, Published under Cement NewsA recent EPC distribution terminal project, completed by PENTA Industrial Corp, highlights the benefits of modular design where components can be assembled at the factory without the need to use craft labour near the construction site, saving time. Modular thinking also places environmental control, efficient loading and steel bin storage at the centre of design requirements. By Manoj Mohan, PENTA Industrial Corporation, USA. Modular terminal design allows for the fast construction an... |
Tyres as fuel21 April 2016, Published under Cement NewsThe recycling of used vehicle tyres as fuel has become commonplace in many areas, including the cement industry. What are the implications of using this particular alternative fuel for the chemistry and quality of the resulting clinker? How does the use of waste tyres as alternative fuel affect the chemistry and quality of the resulting clinker? Modern vehicle tyres contain mostly synthetic rubber (60-70 per cent of total rubber content) but also some natural rubber (C5H8). Synt... |
Modern trainspotting15 April 2016, Published under Cement NewsWhile many railway enthusiasts enjoy the sighting and recording of trains, ie trainspotting, as a hobby, cement producers have a commercial interest in tracking and scheduling their rolling stock. Latest advances in software technology are playing an increasing role in all aspects of railway bulk materials distribution, helping to keep deliveries on track. By Thomas Bergmans & Dirk Schlemper, INFORM GmbH, Germany. Keeping track of rolling stock is essential for cement producers as the... |
Conveying strengths21 March 2016, Published under Cement NewsModern cement plants involve the movement of a wide range of materials requiring durable equipment suited to the specific application, whether it is the conveying of raw materials, fuel or final product. However, changes in materials, such as the increasing use of alternative fuels, affect the design of conveyor belts, often requiring the original design to be adapted accordingly. By ContiTech, Germany The ContiTech Conveyor Belt Group offers solutions for the entire cement production... |
Managing alternative fuel supplies on arrival16 March 2016, Published under Cement NewsAlternative fuels and raw materials often arrive at a cement works from an external pretreatment facility. Their efficient use includes the need to convey, store and dose them according to the requirements of the production process. By Beumer Group GmbH & Co KG, Germany. Alternative fuels are conveyed from the storage area to the main burner in a low-noise and dust-proof operation With energy accounting for around 30 per cent of production costs, the use of fuel alternatives is ... |
Fans of saving energy29 February 2016, Published under Cement NewsWhen Hanson Cement’s GGBS factory in Purfleet, UK, was looking to achieve energy savings, it chose to upgrade the fan of Mill 3 with Siemen’s Integrated Drive Systems concept. The new drive and motor has enabled the plant to reduce drive speed and power consumption, thus saving 4.5Wh/t on its overall process with this one fan drive. By Siemens AG, Germany. Siemens IDS concept helps cut energy consumption and costs at the Purfleet plant, UK (Courtesy of Hanson Cement/Siemens AG) ... |
Dynamic mercury control24 February 2016, Published under Cement NewsRecent environmental legislation requires US cement plants to tighten up their mercury control procedures. ADA Carbon Solutions has developed the Dynamic Mercury Index test to help ensure consistent quality of sorbents used in activated carbon injection and, as a result, maintain an effective mercury control process. By Chris Vizcaino and Sheila Glesmann, ADA Carbon Solutions LLC, USA. Figure 1: dynamic mercury control laboratory set-up T o help meet the US Maximum Achievable Co... |
Seal of approval17 February 2016, Published under Cement NewsKiln seals help improve kiln control and place lower demands on ID fans and burner output. Available in different guises and each with its own advantages and drawbacks, can combining sealing technologies eliminate weaknesses of individual systems to provide more effective, longer-lasting seals? By Shawn Sutton, IGS Industries Inc, USA. Figure 1: FlexMET sealing system uses overlapping leaves that are swept according to the direction of rotation Kiln seals are an integral part of... |
New grinding dimensions03 February 2016, Published under Cement NewsAs the global demand for cement increases, new cement plant projects are designed to larger production capacities. Alongside this requirement for higher output potential is the need to produce cement more efficiently, using less electrical and thermal energy. This is particularly true in the area of grinding, which accounts for a substantial share of plant power demand. By Alexander Peters and Dr Olaf Hagemeier, thyssenkrupp Industrial Solutions AG, Germany. Figure 1: Polycom S high-p... |
