Primary/Secondary Separators

Primary Secondary Separator Equipment


The combination primary and secondary separators provide mechanical separation of ash from a vacuum conveying air stream through a combination of impact, centrifugal, and velocity change methods. These separators remove material from the conveying stream by increasing the cross-sectional area of the stream when introducing the material to the separator on a tangentially circulation path.

The primary separator removes up to 85% of the material from the conveying stream and the secondary separator removes up to 90% of the remaining material.
