VIBY repairs and maintenance. The thinking behind these recent changes has now come to fruition, with UK sales hitting record highs in 2012, and with Viby's profile and reputa‐ tion now at least as strong as it was 25 years ago. WEIR MINERALS BELT TENSIONER Gemex belt‐tensioning systems – used in many process in‐ dustries worldwide – are now available from Weir Miner‐ als across Europe. The addition follows Weir Minerals' acquisition of Sweden‐based Gema Industri AB, the devel‐ oper of the Gemex system at the beginning of 2012. The hydraulically adjustable and mechanically lockable motor platforms allow belts to be checked and changed rapidly by removing the need to re‐align the motor each time. Belt drives are one of the most commonly used transmission systems across almost every industry sec‐ tor, driving fans, pumps, strainers, crushers, pulpers, compressors and other machinery. quarrying, mining, construction and demolition debris, top‐ soil, recycling, sand, gravel, coal and aggregate applications where site space is at a premium. This aggressive forward‐ facing inclined modular configuration screenbox has a 2,755‐ x 1,200‐mm (9‐ x 4‐ft.) top deck and a 2,755‐ x 1,200‐mm (9‐ x 4‐ft.) bottom deck. Depending on the work‐ ing application of the machine, the screen box angle can be adjusted hydraulically between 14–18 degrees. The top deck of the screenbox can be fitted with a variety of screening media including tines, bofor bars, punched plate and mesh. The bottom deck can be fitted with mesh or cas‐ cade fingers. A high performance 1000‐mm (40‐ft.) 4‐ply belt feeder, with hydraulic gearbox drive, is fitted to the ma‐ chine as standard and has proven performance and versatil‐ ity in demanding and varied working environments. The hopper has a 5 cu. m (6.54 cu. yd.) capacity as standard. VIBY ATTACHMENT SERVICE Viby Attachment has invested not only in dedicated UK sales representation for the first time, but also in setting up partnerships with other organisations in the UK to demon‐ strate – and deliver – its commitment to after‐sales sup‐ port. For example, it has set up a next‐day parts delivery service partnership with Spillard Safety Systems, from its depot in the West Midlands, as well as a partnership net‐ work of expert engineers in the UK to ensure any urgent ROCKproducts • AUGUST 2012 19 Monty Riemann, Gemex product manager at Weir Miner‐ als, said: "Belt‐drive systems underpin a vast number of industrial processes across a wide range of sectors, be‐ cause it has a number of innate advantages over alterna‐ tive transmission methods, being quiet and highly efficient and delivering a large load capacity for its size. The Gemex belt‐tensioning system removes one of the only down‐sides to belt‐drive systems – the time consum‐ ing process of changing worn out belts – by ensuring that alignment is only done once on installation. The drive transmission is a critical cog in any process and downtime can be very costly, so the potential savings this system can deliver are significant." E WEIR
