Rotorrake
The Rotorrake tackles macerating tasks where others have
failed – for macerating very coarse solids and rags.
Depending on the application, the single-
shaft macerator is
available with or without debris collector.
CONSTRUCTION AND
FUNCTION
The quick-release cover
Access to all wetted parts through the
quick-release cover – maintenance
without removal of pipe or drive systems
(MIP).
The blades and counter blades
Blades and counter blades are assembled
alternately on the carrier shaft. The
blades are moved by the rotating shaft.
The stationary counter blades are locked
into the casing.
Debris collector
Solids that cannot be macerated are
collected in the debris collector
(with drainage device at the side).

OPERATING PRINCIPLE
The solids containing liquids flow through the stationary counter blades which are
arranged at an angle. The solids are captured by the counter blades and shredded
by the cutting action of the rotating blades. The reduced solids then continue to
flow suspended in the liquid.

Without debris collector
WITH OR WITHOUT DEBRIS COLLECTOR
Depending on the application, the Rotorrake is installed with or without
debris collector (16 l or 150 l). When operating conditions change, the
debris collector can be retrofitted, replaced or removed.

FLEXIBLE INSTALLATION
The Rotorrake offers high flexibility for the installation. The flow
direction can be changed subsequently (please find a small
selection of options here).
