Pulping systems that remove rejects and contaminants generate quality stock.

The Cellwood pulping system by Grubbens epitomizes what a fully engineered system must deliver. The Grubbens Reject Separator is an integrated unit with a high consistency pulper and contains the screen plate for the system. Pulp impurities are removed without heavy particles being discharged against the rotor and screen plate. Grubbens designs pay special attention to ease of maintenance of the rotor and screen.

Grubbens High Density Cleaners take care of unwanted particles and removes them from the suspension using the vortex separation principle. Parts that have a higher density than the pulp, such as screws, nails, staples, steel parts, stones and pebbles are effectively removed and gathered in the reject chamber.
