Mobile pre-separator from Dustcontrol - wheelbarrowWhen large quantities of material are to be separated, it is advisable to use a pre-separator. The pre-separator can be placed at the work place or in conjunction with the central unit.

When a pre-separator is to be used the following should be considered:

  1. Type of dust to be handled.
  2. Where the unit should be placed and how emptying will be performed.
  3. Expected airflow.

Pre-separators can be used in all applications where the extracted material is coarse or voluminous. These can be placed in the actual workplace for separate handling or recovery of the extracted material, or centrally.

Pre-separators separate material from the air-flow using the action of a cyclone or with inertial separation. Inertial separators are generally configured as containers with the inlet and outlet in the same wall of the container. When the air-flow changes direction abruptly, separation occurs for the particles with higher relative mass.

When pre-separation is used to accommodate higher material volumes it is also important to consider the type of material discharge to be used. Dustcontrol offers a range of different standard options including; screw compaction, airlocks or container collection.
