CONVEYING
Part of Bedeschi pipe conveyor system for Indian Power Company Mahagenco installed power is 8,370 kW. Due to their capability to make tight horizontal curves, the pipe conveyors allow to follow a complex path along the transport route, reducing dramatically the number of transfer towers otherwise required with a conventional troughed conveyor.
Finally, Bedeschi says it 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. Optimised and flexible conveyor routes, with vertical and horizontal curves, enable narrow corridors, a significant reduction in earthworks( excavation and filling) and tunnels, and the minimisation of bridge construction 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. Utilising booster drives significantly reduces belt tensions on long conveyors and high lifts.
Conveyor belt tension is crucial for efficient and safe operation. It is precisely maintained by take-up systems, which Bedeschi says are carefully chosen to match the specific plant layout and operational needs.
Both vertical and horizontal take-up arrangements are employed, utilising various mechanisms to ensure accurate belt tension throughout all stages of operation. These mechanisms include gravity / weights that provide constant tension, automated electric winches for controlled, adjustable tensioning, and hydraulic systems for powerful, precise tension control.
By selecting the appropriate take-up system, optimal belt tension is consistently maintained, resulting in 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. Still, any other drive arrangement can be implemented

at the customer’ s request. Depending on the required drive power, motor voltages range from low to medium voltage, based on the customer’ s grid characteristics and specifications.”
The company adds:“ Nowadays, the preferred motor control and operation method is the variable-frequency drive( VFD) to optimise starting and provide variable belt speeds for varying 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-effective technical and economic solutions for specific drive applications.”
