Pulper Rotor type S

Grubbens rotors are specially designed to operate at high consistency with baled pulp or broke. Regardless of whether it is bales, paper machine web or guillotine broke, high consistency is essential for achieving optimum results.

Grubbens new rotor type S is a further development from the well proven SRM-rotor.
The rotor Type S was specially developed for breaking up wet strength and other difficult paper qualities. The rotor Type S can be equipped with counter knives in exactly the same way as the rotor Type SRM.

Advantages with the rotor Type S:

• The rotor combines hydrodynamic and mechanical breaking of the pulp

• The design of the vane at the rotor prevents plugging of the strainer holes 

• The rotor can break up tough paper qualities, especially wet strength qualities

• The rotor allows higher pulp consistency through the strainer holes

• The rotor gives a higher flow of the pulp over the strainer plate

• The rotor assists emptying of the pulper because it normally gives an overpressure on the suction side

• Rotor Type S fits on the existing bearing unit for Type SRM without modifications
