Deflaker - Virgin Pulp Systems Brochure

Grubbens deflakers are used for separating of fibres in broke systems, virgin pulp systems and waste handling. Even wet strength paper qualities can be deflaked. In the Grubbens deflaker the pulp passes through eight vibration zones under continuous flow reversals and is therefore well processed without fibre bundles in spite of the low peripheral speed. The design of the deflaking discs allows compensation of wear through axial movement of the rotor disc. The discs are made of hardened, acid-resistant steel with Brinell hardness of about 400 HB.
