Pulper service

ANDRITZ offers upgrades to pulpers from many OEMs to increase capacity and reduce energy consumption

Years of experience designing and manufacturing stock preparation equipment enable ANDRITZ to provide a wide range of services for pulping and surrounding processes.

High consistency pulper rotor 

ANDRITZ pulper services, including wear (screen plates/extraction plates) and replacement parts, are applicable to pulpers (including drum pulpers), detrashing machines, and disc sorters independent of the original manufacturer.

ANDRITZ pulper upgrades

Based on decades of knowledge, ANDRITZ offers state-of-the-art pulping technology such as the FibreSolve rotor for virgin fiber and broke pulping, including all kinds of under-machine pulpers also in combination with screen plates/extraction plates. The special rotor design (pumping vanes to create stock movement) allows consistencies up 10%. Reduced energy consumption and/or an increase in production are typical results of such upgrades.
