More stringent air-pollution laws are drawing more attention to the off gas cleaning facilities of industrial and power plants. Nowadays, bag filters are gaining more and more attention also in medium and high temperature applications. Typical problems arising from physical function and chemical impact will be featured in this article.
Belt weighing is common practice in lots of bulk solid handling operations. Although it’s a long established technology, there are still bits and pieces regarding installation and maintenance which might lead to erroneous results. Following you can find the reasons why.
The availability of natural sand for concrete production is facing challenges, while the so-called waste stockpiles at aggregate crushing areas are causing problems for producers. This means that the industry has a huge need to solve this challenge by finding suitable technology for usable crushed sand production.
Belt conveyors in hard rock mining further the development of belt conveyor components on the high end of their performance spectrum. New, superior requirements regarding conveyor geometries and the range of mass flows demand to think about alternative drive concepts.
India based JSW Group, a USD 11 Billion conglomerate with commodities in different sectors of industry, has put up a 1200 MW power plant in Maharashtra state. For supplying the power plant with coal they installed a covered storage facility in the purpose built private port of Jaigarh.
Sempertrans, part of Semperit Group, together with Aguido, a brand of the Italian ropeway manufacturer Leitner ropeways, developed a new system for bulk transportation over long distances — the 'Flyingbelt', a combination of ropeway and conveyor belt. The unique conveyor belt suspended on ropes connects a limestone mine in South Eastern Brazil with a cement plant owned by LafargeHolcim.
Siwertell, part of Cargotec, has secured a contract to supply a sixth continuous ship unloader for the Mai-Liao power plant in Taiwan. Five large Siwertell unloaders are currently in operation supplying coal to the 4200 MW facility, the third largest in the country. Three of the unloaders were delivered in 2001 and two in 2006. This latest order was booked in Cargotec's 2015 third quarter order intake.
Installations and recent studies have demonstrated the technical and economical advantages of high angle conveying for optimization of any IPCC system, yet that industry continues to struggle with the use of conventional solutions to achieve the high angle function.
Solids flowmeters are an interesting solution to indicate flow rates in pipes and chutes. Matt Morrissey, Product Manager Weighing Technology at Siemens, says 'interesting' because “they are only moderately accurate, costly, require a lot of tuning after installation and are usually only as good as the whole process around them.”
