Big Lift Trucks (BLT) has been appointed distributors in Africa for MDS International, global specialists in trommel screens and apron feeders.
“BLT’s carefully structured expansion programme encompasses a strategy to extend the company’s range of materials handling equipment to meet exact market demand in Africa and the Indian Ocean Islands,” says Ken Mouritzen, managing director, Big Lift Trucks. “MDS trommels and apron feeders, which are also available from BLT on a fully serviced rental basis, are designed especially for mineral processing and recycling applications.
“These flexible systems are used to remove the small fraction – fines - from a waste stream, to make the remaining material easier to handle for the operatives or processing equipment. Trommels are used in the classification of solid waste, treatment of waste water and recovery of valuable minerals from raw materials. They are also used in the screening process of composts and in food industries, trommel screens sort dry foods of different sizes and shapes.”
MDS trommels can be designed and manufactured to exact specifications and vary in terms of dimensions of the trommel width, diameter and aperture of holes. The size of fines removed by the trommel screen is predetermined by the holes in the trommel drum and varies depending on the operation, waste stream, volume of material and product specifications.
Heavy duty MDS trommels, which are available as mobile and stationary units, have output capacities between 250 and 1 000 Tons per hour and can handle rock size up to 1,5 m.
The M515 track trommel, with a 30 T hopper capacity, is supplied with fold out stockpiling conveyors and can move around a mine and from one site to another. This machine, the most popular in the MDS range, is capable of producing three products concurrently, at an output of over 400 Tons per hour. In a recent project, this machine removed fines up to 120 mm through the swivel fines conveyor at the rear of the unit. A mid-sized product (120 – 250 mm) was produced through the left conveyor and oversize materials (250 – 750 mm) out the front of the front of the machine. A notable feature of this unit is that it is also able to separate difficult and sticky materials.
M615 static trommels are designed for removing soils and fines from rip rap or blasted rock. These machines have an output capacity between 350 and 500 Tons per hour.
The M820 unit is a large, heavy duty rock trommel, capable of screening rock up to 1 m in size, at approximately 750 Tons per hour. This modular machine is available with three or four splits and is suitable for cleaning dirty rock or for screening blasted material.
The static M825 machine, which handles rocks up to 1,5 m in size, is perfect as a primary screener for material direct from a blast. The hopper, with 100 Ton capacity, can be loaded by dump trucks, with an output of 1 250 T per hour. This unit is also available with an hydraulic rock breaker.
The heavy duty, recycling M820R trommel, with 15 mm thick steel screens and apertures between 10 and 250 mm, is designed for concrete and demolition waste separation.
Also in the range is the M520R, which is used for light recycling materials, including compost and wood bark. Screens, with apertures between 5 and 50 mm, can be changed easily to suit specific requirements. This machine has an output capacity of approximately 15 Tons per hour.
MDS apron feeders, with an electric or hydraulic drive, are available as standard units for quarries, aggregates or recycling applications and as heavy duty machines for mining, ore and coal environments.
Big Lift Trucks also supplies an extensive range of container handling equipment, as well as variable reach trucks, mobile container handlers and terminal tractors. Automated bulk handling systems include link conveyors, grab hoppers, surface feeders, radial boom stackers and mobile shiploaders.
The company offers a technical advisory, spare parts and maintenance service throughout Africa and the Indian Ocean Islands.
