Loss of material can be expensive in the long term for operators of conveyor systems such as those used in coal mining, underground mining or in gravel plants. The energy of impact during transfer is a frequent reason for the loss. Flexco Europe GmbH supplies and installs impact beds that slow down the speed at which the bulk material falls (Fig.). This absorbs the impact energy and prevents damaging vibration. This solution from Flexco significantly increases the service life of conveyor belts, as these are subjected to much less load.
Flexco supplies impact beds for a wide range of applications. In order to select the appropriate impact bed, the user needs to ascertain the weight of the largest materials that are to be conveyed as bulk. This figure is then multiplied by the height of the fall. The result gives the approximate impact energy. If the user is conveying coarse, large-sized bulk material at great heights, for example, very strong impact forces can quickly be generated. The DRX3000 impact bed is equipped with additional vibration damper for this purpose. These absorb most of the energy that occurs upon impact. In addition to these, there are fixed impact rails at the sides. Together with skirt clamps, these seal off the transfer area.
High impact forces can also occur on conveyor belt systems that are used in coal-fired power stations, coke plants and unloading stations, as the materials can be up to 30 centimeters in diameter. Flexco offers DRX1500 impact beds to provide additional force reduction with isolation bars that further absorb the impact.
For applications with moderate impact forces, Flexco offers the DRX750 impact bed. These are used in belt conveyors that, for example, transport limestone or hard rock with material sizes up to 25 cm. These impact beds are also equipped with isolation bars. For rock sizes up to 15 cm, gravel for example, Flexco has the DRX200 impact beds in its product range.
