The finished material from grinding plants is first separated in the SEPOL® high-efficiency sep

arator and then, depending on the plant situation, either goes directly to a dust collection filter or first goes to high-efficiency cyclones for primary dedusting. In a SEPOL® closed-circuit air separator the entire finished product is collected in high-efficiency cyclones.

The Polysius high-efficiency cyclones used for this purpose are compact units that have a large operative range and high collection capacity with relatively low pressure drop.

Depending on the abrasiveness of the material to be collected, the cyclones are provided with special wear linings.
