Vacuum filter conveyor belts for washing coal

Vacuum filter conveyor belts is an area in which fluid and solid components have to be separated is primary raw material extraction – the washing of coal and ore in mining operations. This generally includes two distinct tasks that have to be fulfilled:
1) the drying of concentrate and processing of tailings and
2) the drying of heavy and coarse materials and ores in
mining operations.

Vacuum filter conveyor belts separate solids and liquids. If required, this can be accompanied by rinsing, leaching or acid washing. The belts form a Monster circulating trough that holds and transports the filter cloth, the filter cake, the suspension and the washing solvent and removes the filtrate. The force of gravity and the vacuum generated cause the filtrate to be siphoned off via the belt grooves and through the drainage holes in the center of the belt. Beside a good chemical resistance and high temperature stability the Vacuum Filter Belts have a non-textile suction zone made of cover rubber compound, which has same resistance properties as cover rubber. Consequently, punching of center holes does not result in exposed fabric.
