Reaching the destination without losses

For the operators of conveyors like those used in coal mining, underground mining or at gravel plants, material losses can become very expensive in the long run. A common cause of such losses is the impact energy on material transfer. Flexco Europe GmbH supplies and installs impact beds that brake the fall velocity of the conveyed material. It absorbs the impact energy and avoids damaging vibrations. With this solution, Flexco can substantially lengthen the lifetime of conveyors belts because these are then exposed to much lower loads (Fig.).

Flexco supplies impact beds for a wide range of operating conditions. To select the optimum impact bed, the user has to determine the weight of the largest materials in the conveyed material. This is then multiplied by the fall height. The result shows the approximate impact energy. If, for example, the user transports coarse, large lumps of bulk material at extreme heights, very high impact forces soon result. The DRX3000 impact bed is equipped with additional vibration absorbers. These absorb a large part of the energy on impact. In addition come fixed impact cheeks. Together with a side sealing system, these seal off the transfer point.

At belt conveyors used in coal power stations, coking plants and unloading stations, high impact forces can also be generated, as the conveyed material has diameters up to 30 cm. To reduce the restoring forces, Flexco supplies DRX1500 impact beds. These are supported on rubber buffers which further reduce the impact. For applications with medium impact forces, Flexco supplies DRX750 impact beds. These are used in belt conveyor systems for conveying lime or hard rock with material sizes up to 25 cm. The impact beds are also supported on rubber buffers. For rock sizes to 15 cm, as found in gravel, Flexco includes the DRX200 impact beds in its range.
