Bedeschi offers reliable conveyor solutions for uninterrupted and dependable material transport over long distances.

The overland conveyors by Bedeschi are highly sustainable due to their efficient use of raw materials and low energy consumption.

Optimized and flexible conveyor routes with optimized vertical and horizontal curves enable narrow corridors and a significant reduction in earthworks (excavation and filling) and tunnels, as well as a minimization of bridge constructions and transfer points. This approach reduces lead times, installation costs and environmental impact.

Combining low rolling resistance (LRR) conveyor belts, precision-engineered conveyor modules with highly accurate roller alignment, and high belt speeds provides lower belt drag resistance at lower belt tensions/drive torque, as well as reduced belt widths and compact components. Utilizing booster drives significantly reduces belt tensions on long conveyors and high lifts.

Conveyor belt tension is crucial for efficient and safe operation and is precisely maintained by take-up systems which are carefully chosen to match the specific plant layout and operational needs.

Both vertical and horizontal take-up arrangements are employed, utilizing various mechanisms to ensure accurate belt tension throughout all stages of operation. These mechanisms include gravity/weights provide constant tension, automated electric winches for controlled and adjustable tensioning, hydraulic systems to provide powerful and precise tension control.

By selecting the appropriate take-up system, optimal belt tension is consistently achieved, leading to reliable and efficient conveyor performance.

Energy-efficient conveyor drive solutions provide reliable drive arrangements and meet all operational requirements or preferences.

Generally, overland conveyors are equipped with pulley-shaft-mounted geared motors to reduce the size and weight of the drive arrangement, but any other drive arrangement can be implemented at the customer’s request. Depending on the required drive power, motor voltages vary from low-voltage to medium-voltage, considering the customer’s grid characteristics and specifications.

Nowadays, the preferred motor control and operation method is the variable frequency drive (VFD) to optimize starting and provide variable belt speeds for various material densities and conveying capacities, resulting in less wear and tear and lower energy consumption. However, constant filled and filling controlled fluid couplings as well as resistor-starters are still viable and cost efficiency technical and economic solutions for specific drive applications.

Latest technologies for mining conveyor drives are being addressed by the introduction of gearless drives, ranging from small- to medium-sized permanent magnet motors to large externally excited synchronous machines. The highly energy-efficient direct drives reduce maintenance costs and avoid environmental hazards such as the spillage of gear lubricants. Permanent excited magnet motors provide relatively light and compact drive arrangements with minimized cooling requirements, which makes them ideal for confined spaces, underground applications and retrofitting existing conveyors.
