International technology Group Andritz, Austria, has successfully started up a FibreFlow drum pulper, type FFD225, for the Spanish tissue producer ISMA 2000 S.L. The new drum pulper processes various recycled fiber materials and is designed for a feed capacity of 120 metric tpd.

 

The drum pulper has replaced an existing conventional pulper to raise the pulp quality for production of premium tissue products. The scope of supply also included engineering services as well as installation supervision, startup, and commissioning support.

 

 

 

ISMA 2000 produces its environmentally-friendly tissue papers—sold under the name Ismax—from 100% recycled paper, ranging from mixed and sorted office waste and colored ledger to various card and paper board grades as well as packaging and laminated paper. For these raw materials, the reject content to be removed by the pulper ranges from 2% to 20%. The Andritz FibreFlow drum FFD can flexibly handle this wide range of fiber sources at lowest energy consumption and maximum yield.

 

With the Andritz FibreFlow drum pulper technology, a variety of cheaper wastepaper raw material composites can be used, without compromising the performance of pulping and paper production. The new design of the FibreFlow drum pulper type FFD225 enables a reduction of the installed power for the pulping process as well as paper producers to use raw material mixtures from UBC (used beverage cartons) and polyethene-coated papers to OCC (old corrugated containers) and office waste grades.
