Capital-saving solutions for crushing and screening

ing facility in Gauteng allows it to conduct an entire plant construction almost entirely in- house, according to customer requirements. Its control of the whole value chain raises quali- ty levels, holds down costs and shortens lead times. “We have engaged in a num- ber of successful contracts where we undertake to design, construct and operate a plant on behalf of a mining customer, so that they can focus on other im- portant aspects of mining,” says Weideman. “We retain owner- ship of the plant and charge a toll rate depending on the pro-

As some rising commodity prices bring the sparkle back into potential new mining projects, raising enough finance remains a challenge. B&E International, specialist in crushing and screening plants, has a toll model that reduces the capital demands of mining entrepreneurs. “Many smaller operators – or those who are new to the mining business – often find it difficult to raise all the necessary capital for starting up once the feasibility studies have proved a project viable,” Chris Weide- man, director operations at B&E Interna- tional, says. “They may also lack the in- depth expertise required to establish and operate a processing plant cost-effectively and efficiently; that is where we come in.” For more than 40 years, B&E Internation- al has been developing its capacity to de- sign, build and run process plants, and has the experience of operating in many coun- tries, mostly in sub-Saharan Africa. The construction sector is also a key focus area of B&E International, building and operat- ing aggregate crushing plants for a range of applications. The company’s extensive manufactur- BLT reports that the mining sector in Africa has shown particular interest in its MDS trommel screens and apron feeders, designed especially for mineral processing and recycling applications. BLT supplies an extensive range of heavy duty materials handling equipment into Africa, which includes trommel screens, link conveyors, grab hoppers, surface feeders and radial boom stackers. “By using trommels to remove clay and wet sticky material, crusher and vibratory screen blockages are prevented and this contributes to increased production,” says Ken Mouritzen, MD of BLT. “Flexible MDS systems are used to remove the small frac- tion – fines from a waste stream, to make the remaining material easier to handle for the operatives or processing equipment.” Heavy duty MDS trommels, which are available as mobile and stationary units, have output capacities between 250 and 1 000 t/hour and can handle rock size up to 1,5 m. “The most popular machine in the MDS range, the M515 track trommel with a 30 t hopper capacity, has been supplied with fold out stockpiling conveyors and is able to move around a mine and from one site to another. This machine is capable of producing three products concurrently, at an output of over 400 t/ hour,” says Mouritzen.

By providing a turnkey crushing solution, B&E International can optimise a customer’s operation.

duction output. This removes the financial burden of paying upfront for their process- ing plant, and reduces the risk of that plant underperforming to the detriment of the whole project.” He says there is also the option for the customer to take back ownership of the plant after an initial five year to seven year period, where they would pay only the residual value

of the plant based on an amortisation formu- la that could be agreed in advance. In addition to its head office and branches in South Africa, B&E International has per- manent bases in Namibia and Botswana; it has worked in countries including Uganda, Kenya, Tanzania, Malawi and Zambia, and has also sold equipment into the Demo- cratic Republic of Congo. b

BLT trommels and feeders offer cost-effective solutions for mining

BLT’s SAMSON MF0814T material feeder has a holding capacity of 100 t.

between 350 and 500 t/hour. The M820 unit is a large, heavy duty rock trommel, capable of screening rock up to 1 m in size, at approximately 750 t/hour. The 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/hour. This unit is also available with an hydraulic rock breaker. b

“In a recent project, the machine re- moved fines up to 120 mm through the ra- dial 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 end of the machine. A notable feature of this unit is that it is efficiently separates difficult and sticky materials and handles large ROM.” Other units in the range include the M615 static trommel, designed for remov- ing soils and fines from rip rap or blasted rock. The machine has an output capacity
