Operating principle

The Rotorrake is a blockage-free single-shaft coarse chopper with radial flow and excellent extraction of hard substances. Its powerful chopping force enables the Rotorrake to be used in applications such as waste water processing for effective chopping of solid items.

The solids fed in with the liquid flow through the counter blades which are fixed at an angle. The solids are then captured by the counter blades and chopped by the cutting action of the rotating blades. The chopped solids then continue to flow with the liquid. Coarse objects which cannot be chopped are ejected into the debris collector.
