Hydrosizers

Hydrosizers are effective for the beneficiating of fine coal. They work best with particles smaller than 1mm.

Operation

The hydrosizer is a large vessel with a constant upward flow of water through the vessel and over the rim.

The lighter coal particles rise to the top and overflow the rim. They are then pumped to cyclones and dewatering screens.

The heavier shale particles slowly settle through the upward flow of water and are discharged at a controlled rate from the base of the vessel.
