Belt Conveyors - for mining applications
Belt conveyor systems continuously transport all forms of material, including excavated and crushed rock, in an efficient manner due to their 100% effective availability. They cover a wide range of applications, from mining or extraction to in-plant or overland where they convey material over long distances, passing through curves and rough relief areas.
Open-pit or underground applications and In Pit Crushing & Conveying (IPCC)
Our conveyors are specifically designed for their application and each project’s unique requirements covering a wide range of commodities and capacities. TAKRAF conveyor systems are employed globally from open-pit to underground mines where they generally convey crushed material from a primary crushing station to a stockyard, material processing plant or spreader from various areas within or out the pit or alternatively from underground to aboveground. Our mining conveyors are also employed extensively across various areas of a mining operation and form an integral part of an IPCC system efficiently conveying material crushed out of the pit.
Conveyor lengths can vary from short distances up to many kilometers in deep mine or underground applications overcoming significant vertical elevation change too. Belt widths vary according to the material to be conveyed and capacity required together with the manner in which they are constructed. Depending on requirements, our conveyors can also integrate scales, detectors or material analyzers and sampling equipment.
Open-pit mine applications
According to an open-pit mine's development, conveyors are also often required to be relocated or shifted and may include special features for extension requirements including belt storage at the tail end and a crawler-mounted drive station at the head end. Belt storage devices reduce the number of belt cut & splice procedures during conveyor extension operations.
Other typical applications for open-pit conveyors are mobile transfer points like tripper cars, hopper cars and shuttle heads for material feed to several downstream conveyors. Our diverse product range includes tripper cars on rails or on crawlers as a mobile link between dump conveyor and spreader, as well as hopper cars on rails or on crawlers between excavator and bench conveyor. Bench conveyors for mining and dumping are designed as shiftable conveyors, where the conveyor modules are equipped with steel sleepers and rails to allow for an easy shifting procedure. Our product range also covers shifting head fabrication and testing in our specialized fabrication facility.
Gearless drive technology
TAKRAF is one of a very limited number of global conveyor manufacturers boasting an operating reference in the use of advanced gearless drive technology in mining conveyor systems and are proud of our association with our drive technology partner, ABB.
Gearless drives eliminate the need for a gearbox, hereby significantly reducing the number of main wear parts, which results in increased efficiency and reliability, as well as less maintenance being required. Further advantages include a considerable reduction in the drive system’s footprint and emissions. In fact, for a copper mine in Chile, studies showed that CO2 emissions are reduced by 66% as compared to diesel truck engines for the same copper production volume!
The world’s most powerful belt conveyor system!
In 2019, TAKRAF delivered equipment for the principal ore transport system for Chuquicamata, one of the world´s largest copper ore mines, moving ore extracted underground to an above-ground processing plant.
This incredible system, boasting a total installed drive power of 58 MW, transports crushed copper ore from underground storage bins to the surface along a 7 km underground tunnel that overcomes 1 km of vertical elevation. Once on the surface, the ore then travels along an overland conveyor that transports it the final 6 km to the distribution silo. The underground system (comprising two conveyors of about equal length), as well as the overland conveyor, boast advanced gearless drive technology.
Some important parameters of the conveyor system:
- 11,000 t/h crushed copper ore
- 11 x 5 MW gearless belt drives
- 10 MW installed drive power per drive drum
- St 10,000 conveyor belt employed for the first time
- 7,500 tons of steel construction
- 35,000 idlers
- 6 TAKRAF patents

Further to countless belt conveyors installed globally, in 2000 we built a conveyor system with the world`s longest 16.8 km single flight conveyor; of which16 km was inside an inclined tunnel. Other significant achievements in the development of conveyor systems are our installed downhill overland conveyors at El Abra and the in-pit and ex-pit conveyors of the Escondida mine in Chile.
Customer Project Name Waste Rock Conveyor System Goldcorp Co. Penasquito mine 2013
Waste Rock Conveyor System in Mexico
TAKRAF supplied a complete waste rock conveyor system including a spreader for waste dump. Special features of the conveyor system are an extendable conveyor CV-75 with belt storage and crawler-mounted head drive station and the shiftable dump conveyor CV-76 with crawler-mounted tripper car.

Value for Money
- Depending on mine development plans, conveyors often need to be relocated or shifted; as a result, we are able to provide numerous features for conveyor extensions
- We're able to provide a wide-range of capacities, even up to 20,000 t/h
Apron FeedersAn apron feeder is a reliable feeding method for when the material to be conveyed is lumpy, abrasive, heavy, high temperature, or where a feeding solution more robust than a traditional belt feeder is required. Apron feeders are designed to feed material at a desired volumetric rate to downstream equipment and convey material on a series of overlapping pans attached to multiple strands of a heavy tractor crawler-type chain.
Belt FeedersBelt feeders are short belt conveyors that are specifically designed for material flow regulation, extracting material from one area and ensuring that downstream equipment receives the appropriate volume
Mobile Conveyor BridgesMobile Conveyor Bridges (MCBs) operate as flexible links between mining machines and bench conveyors and increase the operating range of the system.
Mobile Transfer ConveyorsMobile Transfer Conveyors (MTCs) are "multi use" equipment that are used to both increase performance and flexibility of many mining operations. Mobile transfer conveyors work as a flexible connection between a mining machine and bench conveyors. Moreover, mobile transfer conveyors are easily relocatable and positionable, improving performance, flexibility and efficiency.
