Counter-current separation drum

Product description

A counter-current separation drum is a robust machine which depends on a simple separation technique. In the past, this technique has been mainly used for the validation of coal, namely the separation of coal and of stones. The principle of rinsing and washing in a rotating drum, with a certain slope, is retained, but has been implemented in a modern machine and further elaborated. This technique has been improved and taken to a current level of technology. The ultimate goal of a counter-current separation unit is to disassemble mixed materials, with a different specific weight, in an economical and simple mechanical way.

The separation drum system consists of a rotating drum with internal screws. Due to its robust design, the machine is easy to operate. The model depicted here is a separating drum with a counter-current operation. The mixed fraction is introduced into the separation drum via a chute and a large water flow. The individual parts are soaked and loosened through the rotating movement of the drum. Then, depending on their specific weight, the parts are split into 2 fractions. These fractions are, separately, delivered to both sides of the device for further processing.

During the design of the counter-current separation drum special attention was paid to the functionality. Specific to this type of separation machine is the especially large processing capacity, the ability to handle relatively large pieces and a wide range of different densities it can process.

This technology is usually implemented in the following sectors:

  • Primary resources: Coal, control for “ash content”
  • Soil cleaning plants: Separating polluted soil from organic material, separating broken glass from organic contaminants, washing plastic.
  • This technology can be implemented wherever a separation of mixed products is required. The only condition is that the products have a sufficiently different density.
