Belt conveyors complement machines used in bulk material handling and mining systems. They are used as the main component in bulk material transport systems.
The conveyor length can vary between short distances up to approximately 20 km in single flights. Typical belt conveyors application fields are:
- Boom conveyors/intermediate conveyors in yard machines, in mining machines and in ship loading facilities
- Belt feeders / feeder conveyors for hopper discharge
- In-plant conveyors
- Overland conveyors (stationary and shiftable) with or without horizontal curves
The conveying capacity can vary between some 100 t/h in bulk materials handling up to 50,000 t/h for overburden handling in mining.
We design, fabricate and supply a wide-range of belt conveyors ranging from capacities of 100 t/h to 50,000 t/h
- Our systems are specifically designed for our clients' unique requirements and can be either stationary or shiftable

Customer Project name Overland conveyor system Climax Molybdenum Co. Henderson mine in Granby, Colorado 1999
One of the largest conveyor systems in the world
Molybdenum ore has to be moved from the underground mine up to the processing facilities. A train system was replaced with a chain of belt conveyors. The main conveyors at this project are the tunnel conveyor PC 2 and the overland conveyor PC 3.
Tunnel conveyor PC 2
With 16,820 m pulley center distance and 471 m lift this conveyor is still one of the largest conveyors worldwide.
With the task to design an energy efficient system with reduced capital costs for belting and drives several investigations were made. The Hannover University in Germany was one of the scientific institutions where tests for indentation resistance and idler running resistance were carried out. An optimized conveyor design in combination with a suitable component selection was leading to a very low conveyor running resistances with a recalculated f-value of 0.009.
Overland conveyor PC 3
The overland conveyor PC 3 runs though the national forest with horizontal and vertical curves following the natural terrain.

Feeder conveyor system at Lomas Bayas pant in Chile
Belt Feeders are state of the art for emptying hoppers with crushed material. The belt runs at flat idler stations with maximum 0.5 to 0.7 m/s belt speed. The bulk material shape at the belt is rectangular defined by the spacing of the chute side walls and the adjustment of the shear gate. For longer transport distances (20 m and more) the material has to be transferred to a standard trough conveyor - a conveyor system with less chute wear and lower power demand.
The feeder conveyor
If the distances between hopper discharge and the next system feeding point is between 20 m and 75 m a feeder conveyor could be used as a combination of the feeder (hopper discharge) and conveyor. This type of conveyor has a standard trough shape (35° to 45° troughing angle) at the full length. Hopper side wall lengths are reduced to the discharge area section length only. A shear gate limits the material height at the belt. The shape of this shear gate defines the contour of the material surface. Feeder conveyors run with maximum 1.4 m/s belt speed and 80 % to 100 % capacity utilization. Compared to the combination between feeder and separate conveyor the feeder conveyor has lower CAPEX and OPEX because of the saving of a transfer point and the lower amount of friction between chute site walls and material.

In-plant conveyor system for stockyard in Leningrad oblast
Delivery of the complete in-plant conveyor system for stockyards including transfer towers, elevated structures, transfer chutes, trippers etc. Besides to the yard machines the stockyard as part of the Ust Luga port comprises:
- 11 transfer towers with complete transfer chute arrangement
- 16 belt conveyors from 90 m up to 520 m in pulley center distance

Overland conveyor with 8,120 m pulley center distance
Copper ore has to be moved from the crusher location to the processing facilities. The main conveyor at this project is the overland conveyor with 8,120 m pulley center distance. This conveyor is following the natural ground profile and runs in 63 % of its length in horizontal curves – partly in superposition with convex and concave curves. Up to 17° banking angle in combination with idler tilt are used to realize the steep horizontal curve radii.
