Examples of use
Digestion tower convection
Digestion tower convection
A waste water treatment plant was having serious problems with the build-up of clumps in their sludge. The choppers installed were not able to cut up the voluminous clumps in a passable size. This caused constant blockages in the rotary pumps which were supposed to keep the contents of the digestion tower circulating. The operator of the plant decided to try out a Boerger Rotorrake. The Rotorrake is a robust chopper. Blades and counter blades are mounted one after the other on the carrier shaft.
The Rotorrake was tested intensively for a long period of time. During that time, no problems occurred with the Rotorrake and no signs of wear could be detected on the blades or counter blades after the test phase.

Pumping station
Pumping station
A pumping station was experiencing continuous problems when pumping waste water with coarse solids, cause solids in the pumps which led to subsequent downtime. Solids such as fabric scraps and plastic containers got caught in the pumps and blocked the system.
The pumping station operator then tested various chopping units from different manufacturers. All the choppers tested had difficulties coping with the coarse solids in the medium. Then they tried the Boerger Rotorrake, especially designed for coarse solids. The operator of the pumping station was impressed by the powerful Rotorrake. No downtime from problems with solids has occurred since the Rotorrake has been in operation. The customer is extremely satisfied with the Boerger Rotorrake.
