Broke pulping

Designed to meet all demands for under-the-machine and finishing broke pulpers.

The extensive reference base of Valmet’s Broke Pulping Technology confirms the success of the Valmet Broke design for a wide range of applications. Combined with a special rotor design, Valmet Broke Pulpers deliver high pulping efficiency in all broke pulping applications.

Energy-efficient rotor unit

The Valmet Broke Pulper rotor delivers a high pumping effect with efficient defiberizing at low energy levels. The standard rotor produces active circulation with pumping vanes, while a sawtooth rotor is used to slush wet-strength, board, coated and special grades, as well as slabs. Extraction and deflaking plates under the rotor are used to deflake and screen the broke to the desired quality level.
