Vtorchermet Commissions Auto Shredder in Russia
Vtorchermet NLMK, one of the largest scrap metal recycling firms in Russia, has commissioned an auto shredder at its facility in Podolsk, Russia. Vtorchermet is a division of the steel mill company NLMK Group.
The Metso Lindemann shredder has been designed for processing both light and mixed scrap. The shredder also is expected to improve the quality of raw material supplied to NLMK Kaluga, the steel company’s electric arc furnace (EAF), as well as other NLMK steel mills. The company says the shredder will reduce the tap-to-tap time and energy usage for the steel mill.
The auto shredder is equipped with a 4,000-horsepower drive and is capable of processing up to 100 tonnes of scrap per hour, the company reports.
The shredder installation is part of a technical upgrade and development program for NLMK’s scrap processing division that the company started in 2011. Under the program, NLMK is looking to double its ferrous processing capabilities in Moscow to 800,000 tonnes by 2016. Since starting the program, Vtorchermet NLMK has opened 18 new sites.
The Metso Lindemann shredder that has been commissioned is the second for the company in the Moscow region; the first auto shredder was commissioned at the company’s Mytischi site in 2010.
Vtorchermet NLMK is the scrap processing division of NLMK Russia Long, part of NLMK Group. Vtorchermet NLMK has facilities at 34 locations in Russia. The company processes more than 3.5 million tonnes of ferrous scrap per year.
MAS Introduces melt Filter Designed to Extract Contaminants from Plastic Scrap
The Austrian company Maschinen- und Anlagenbau Schulz (MAS) has introduced a continuous melt filter that has been designed to eliminate a range of contaminants typically found in the processing of plastic scrap.
The company says conventional filter systems using mesh screens are usually unable to manage even small amounts of impurities. However, MAS’ patented Continuous Disk Filter (CDF) system features a tempered steel, finely perforated filtration disk that rotates in the incoming flow of melt. According to MAS, the filter is highly efficient at holding back impurities such as paper, wood, aluminium, rubber and unmelted plastics from the melt during the process.
The filter is available in four sizes. The basic modules have disk diameters of 300 or 510 millimetres (mm) and, depending on the type, either one or two fitted filter disks.
The newly introduced and largest system, the CDF 500-D, is designed with two filter units in parallel, which have a diameter of 510 mm. The available active filter area is 3,650 square centimetres, which allows a melt throughput of between 1,300 and 2,000 kilograms per hour, MAS says. According to the manufacturer, the twin filter configuration makes it possible to keep the dimensions compact, ensuring that the filter is easy to handle during cleaning and maintenance and during transfers between a number of different extrusion lines when required.
To ensure the disk filter does not clog up during continuous operation, a scraper removes the contamination from the surface of the rotating screen disc, which is discharged continuously from the CDF, while the filtrated melt is forwarded to the pelletizing system.
The company says that despite the considerably larger dimensions and masses of its components, the CDF 500-D filtration unit is as easy to maintain as smaller models of the same type because of its split housing, hinged connections and integrated service crane.
The filter screen can be replaced in about 45 minutes using conventional tools and can be reused numerous times, according to the company.
More information about continuous melt filtration and the CDF 500-D from MAS is available at www.mas-austria.com.
Weir Waste Services Updates Oldbury, U.K. MRF
Kiverco Recycling Systems, based in Dungannon, Ireland, has recently designed, manufactured and installed a new commercial and industrial (C&I) recycling system for Weir Waste Service based in Birmingham, U.K.
The updated material recovery facility (MRF) located in Oldbury, West Midlands, is one of two MRFs operated by Weir in the region.
The Oldbury facility recovers recyclable materials from commercial and industrial waste, diverting thousands of tonnes of waste from landfill each year. The updated plant feeds into the company’s existing Trinity Street refuse-derived fuel (RDF) processing facility, bringing the capacity to in excess of 25 tonnes of waste processed per hour, making it one of the largest commercial and industrial MRFs in the U.K., Kiverco says, and helping the West Midlands Area achieve waste management targets set by the European Union.
Kiverco reports that the plant, which was contracted through waste and construction machinery supplier Blue Group, was delivered on schedule and within budget and marks a significant development milestone for the equipment company.
According to Weir Waste, the facility contains equipment from Doppstadt, Kiverco and Titech, including a Titech autosort 4 system.
“The Trinity Street MRF is the first of its kind for Kiverco and demonstrates our ability to deliver a project on this scale and one which has exceeded our client’s expectations,” says John Lines, sales director for Kiverco. “Our expertise in design and manufacture, our ability to offer materials testing and to effectively partner with leading technology partners such as Titech and Hartner, have all been demonstrated through this contract.”
Waste management specialist Weir Waste Services says it is one of the largest independent waste companies operating in the West Midlands, and that its Oldbury facility is the largest C&I processing facility in the U.K.
Managing Director Daniel Weir comments on the development, “We are incredibly excited that Trinity Street MRF will be bringing new and innovative recycling machinery from U.K. companies such as Kiverco to help us and our customers in our commitments to the environment and sustainability.”
The project was in part funded by the European Regional Development Fund (ERDF) and managed by the U.K.’s Waste and Resources Action Plan (WRAP).
Bühler Launches Optical Sorting Station
The Bühler Group, based in London, a manufacturer of optical sorting solutions, has launched its new Optical Sorting Station (OSS) system at the 2013 K Show, an international trade fair for plastics and rubber held Oct. 16-23 in Düsseldorf, Germany.
According to Bühler, the OSS features various elements of optical sorting, including plant engineering, sorting technology, pneumatic conveyors, pre-conditioners and auxiliary equipment. Because the system is integrated, Bühler says, processors no longer need to source-separate elements from multiple suppliers.
Designed for flake processing, the company says, the OSS features purifying, refining, sizing and grading stages, which can include one or more Sortex optical sorters. According to Bühler, these are linked by the necessary equipment to convey the product between stages and, if required, to reintroduce it into the system for resorting. Flakes can be fed into one end of the station and collected at the other end, ready for bagging or further processing.
“We want to help our customers achieve the most efficient sorting methods on plastic flake processing lines,” says Charith Gunawardena, head of optical sorting for Bühler. “That is why we are launching our integrated Optical Sorting Station system. By taking care of the whole process, from engineering right through to customer support, we can offer processors a consistent, balanced performance in their optical sorting—delivering efficiency and competitiveness for their enterprises.
“We have already installed the full optical sorting station for several of our plastics customers,” adds Gunawardena. “These companies are beginning to see increased efficiency and yield from their processing lines, which of course leads to higher operating profits.”
