Grubbens Pulper

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.

 

The rotor design is the main reason for the pulpers being able to operate at a high consistency and low power demand. The consistency range in the pulpers varies between 3 – 9%, depending on the material and whether the pulpers are operating continuously or batch wise. The primary breaking up of paper and pulp is made by the friction in the pulp stream at high consistency. It is therefore important to have good circulation also with high consistency.

 

It is available in 2 types:

 

  • Pulper Rotor type G
  • Pulper Rotor type S
