ADVANCE MECHANISMS M515 trommels are designed to clean rocks in all weather conditions
Trommel technology leader MDS trommel screens and apron feeders, which have been designed especially for mineral processing and recycling applications, are available throughout Africa from branded machinery supplier BLT World.
“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 wastewater and recovery of valuable minerals from raw materials,” explains BLT World MD Ken Mouritzen.
Trommels are also used in the screening process of composts while in food industries, trommel screens sort dry foods of different sizes and shapes.
“The mining sector in Africa has shown particular interest in MDS M515 track trommels, which are capable of handling large rocks and efficiently separating difficult and sticky materials, like mud and clay. This robust trommel, with a 30 t hopper capacity, is able to produce three products concurrently, at an output of over 400 t/h,” notes Mouritzen.
Additionally, the MDS M515 track trommels have an advanced cleaning mechanism that keeps the drum apertures unblocked. These machines are supplied with fold-out stockpiling conveyors and are able to move around a mine and from one site to another.
M515 trommels are designed to clean rocks in all weather conditions. By using trommels to remove clay and wet sticky material, crusher and vibratory screen blockages are prevented and this efficiency contributes to increased production.
BLT World’s MDS M615 static trommels are designed for removing soils and fines from rip rap or blasted rock. These machines have an output capacity of between 350 t/h and 500 t/h. The M820 unit is a large, heavy duty rock trommel, capable of screening rock up to 1 m in size, at approximately 750 t/h. 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 t capacity, can be loaded by dump trucks, with an output of 1 250 t/h. These units are also available with hydraulic rock breakers.
Also, in the MDS range are trommels designed for light recycling materials, including compost and wood bark.
MDS trommels can be designed and manufactured to exact specifications and vary in terms of the 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.
BLT World’s MDS apron feeders, with electric or hydraulic drives, are available as standard units for quarries, aggregates or recycling applications and as heavy-duty machines for mining, ore and coal environments.
MDS trommel screens and apron feeders, which are also available from BLT World on a fully serviced rental basis, are supported by a technical advisory, supply and repair service throughout Africa.
