Sorting of hard coal is the classic application for alljig^® and allflux^® technologies. A special feature of the alljig^® jigging machines is the compound stroke motion which extends the feed size range and capacity, when processing finer sized coal.

The allflux^®-system allows beneficiation with a high capacity in a single unit.

The latest innovation for the separation of pyrite and rock from coal without the use of water is the allair^®-jig.
