Broke pulping
OptiSlush Broke pulping solutions 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 OptiSlush Broke design for a wide range of applications. Combined with a special rotor design, OptiSlush Broke pulpers deliver high pulping efficiency in all broke pulping applications.
Energy-efficient rotor unit
The OptiSlush 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.
