MULTOTEC GV CYCLONE THE ANSWER FOR TAILINGS DAMS Tailings dams are sensitive to operating costs, and while these operations require quality process equipment, there is a definite need for equipment with a low mass capable of functioning at the required capacity and that will be cost-effective over the life span of the installation. Designed specifically for tailings dam applications, the Multotec GV Cyclone is engineered to ensure sound operational performance while keeping the cost of individual components as low as possible. RichardHaydon, processmanager atMultotec Process Equipment, says it is important that this has been achieved without affecting the structural integrity or quality of the locally developed and manufactured cyclone. “When it comes to cyclone operation on a tailings dam, it is critical to ensure that the right volumetric split between the overflow and underflow is achieved to match the re- quired tailings dam rate of rise,” explains Haydon. Available in different configurations to suit varying application and commodity requirements, Haydon says it is the ability to interchange the spigot and vortex finder on the Multotec GV Cyclone that enables a fit-for-purpose product installation. Optimum flexibility is possible due to the different spigot sizes and vortex finder sizes that are available. By altering the combination of the spigot and vortex finder, it is possible to meet the specific operational parameters. Selection of the size of either component is dependent on the material characteristics, and the tailings dam requirements. Each cyclone is designed for an individual application which ensures that the feed parameters are matched to the cyclone capacity and by doing so the lifespan of the cyclone is optimised. “Where an application is that specific, Multotec will collaborate with the customer to find a unique and appropriate solution, and this hybrid solution will take all factors into account,” says Haydon. This will include materials of construction specific to the application, assuring the customer the best possible wear life. b

Metso helps B&E International break beyond 550 tph

pleted in an existing Metso 9100 vertical shaft impact crusher,” explains Sandro Scherf, CEO of Pilot Crushtec Internation- al, the sole southern African distributor for Metso Mobile aggregates products and services. He adds that the cone crushers play com- plementary roles in obtaining production volumes of this magnitude. The Lokotrack 300GPS is capable of a huge output and key to the success of the train as a whole is the LT330D combination product’s ability to process, screen and recirculate massive volumes of secondary material. According to Scherf, both of the cone crushers were specially purchased by B&E to produce high volumes of aggregate. B&E, which is expected to achieve a turnover of R1 billion in 2016, is an experienced user of Metso Mobile products, operating a fleet of more than 40 Metso units. b

Thanks to the innovative use of Metso Mobile crushing and screening units, South African crushing contractor B&E International has set up a production train that consistently produces G1 road stone product at a rate in excess of 550 t/hour. Incorporating the first Metso Lokotrack 330D combination cone crusher and the 11  m² triple deck screen to be put into action on the continent, this is regarded as one of the first mobile trains in the region to achieve these volumes. “The train consists of four Metso prod- ucts: 700 mm dolerite feed material is first processed by an LT120 jaw crusher and is then fed into a Lokotrack 300GPS sec- ondary cone crusher which is capable of accepting material up to 320 mm in size. This in turn feeds the Lokotrack LT330D combination cone crusher and triple deck screen before quaternary crushing is com-

Metso Lokotrack LT300GP mobile cone crusher and LT120 mobile jaw crusher are being used in a train of four Metso machines.

New MDS M412 for low capacity requirements

BLT has launched the new M412 trom- mel, said to offer cost-effective solutions for smaller production requirements in mineral processing and recycling appli- cations. “This lightweight machine, with a compact design, is able to efficiently handle various materials, from compost recycling to blasted rock,” says Ken Mouritzen, managing director, BLT (Africa and Indian Ocean Islands). “M412 trommels have interchangeable screens for different size rocks – between 10 mm and 500 mm – and are capable of producing four products concurrently, at an output rate of 150 t/hour.” The machines are available as static units or on tracks, depending on customer preference. Other features include the hydraulic push feeder mechanism, an electric/hydraulic power system and easy to operate control panel. The trommels can be used with conveyors and are also fitted with a washing system as an option. The M412 trommels weigh in at

18 t and have a 1,25 m drum diameter and 4,5 m drum length, making them easy to be transported in a container. Other machines in the MDS trommel range include mobile and semi-mobile units, as well as heavy duty static machines for maximum output. Also in the range are static and tracked trommels for light and heavy duty recycling. MDS trommels and apron feeders, which are available from BLT on a purchase or rental basis, are supported by strong technical advisory and maintenance service throughout Africa and the Indian Ocean Islands. b

The recently launched M412

trommel is ideal for smaller production requirements in mineral processing

and recycling applications.
