Twin-screw pulping machine is the key equipment of the TSMP(Twin-screw Mechanical Pulping) technology which can realize compessing and impregnation of fiber raw materials, full high-consistency mixing with chemicals in the machine and simultaneous displacement washing of pulp in the same machine, and improve the reaction efficiency of chemicals and pulp. Therefore, it is a multifunctional high-efficient extrusion and dipping mixer.
Now, the TSMP technology and equipment have been widely utilized in making banknote paper, writing paper and cardboard by using a wide variety of raw materials including softwood and hardwood, textile fibers, annual plants, agricultural waste products and recycled fibers.
A wide selection of raw materials including:
1. Non-wood long fibers such as cotton linter, grade-3 cotton and cotton textile wastes
2. Non-wood short fibers like bamboo chips, cotton stalks and cereal straws and bagasse
3. Wood fibers such as poplar chips, eucalyptus chips and pinus massoniana.
4. Other non-wood materials such as oil palm empty fruit bunches (EFB)
5. Recycled fibers
This process is energy-saving and environmentally-friendly, compared to conventional processes,
20% to 30% reduction in energy consumption for fiber separation
10 to 30% decrease of chemicals and bleaching agents
Reduced water consumption, from 50% up to 90% for certain pulp processes.
