Link-Belt® Aer-Degritter

The Link-Belt® Aer-Degritter provides the best method for the separation of grit from organic matter in domestic and/or industrial wastes. The purpose of the Aer-Degritter is to remove the grit before it can damage machinery or accumulate in the digesters and other plant structures. The benefits of the Aer-Degritter have been proven by over 400 installations in the United States, Canada, Mexico and other foreign countries.

Grit is composed of seeds, coffee grounds, bone chips, eggshells, cigarette filter tips, etc. Some types of industries contribute other types of grit. Therefore, grit is not solely mineral matter such as sand, silt, gravel and other similar debris but a very wide variety of materials, including organic matter.

The Aer-Degritter can be provided with Discfuser Diffusers, Grit Conveyor and with an Air Lift Grit Pump.
