TSMP (Twin-Screw Mechanical Pulping Technology）

——A new high-yield, low energy-consumption and clean pulping technology

The TSMP method is a new high-yield mechanical pulping technology developed by Jinwo Machinery.

The TSMP which has a wide applicability of raw materials, especially applicable to the pulping of non-wood fibre raw materials and remains of wood working (such as poplar slabs bits) can realize low power-consumption, high-yield and low-pollution pulping. The electricity consumption is reduced by 30%, water is saved by 50%, production flow is shortened and the investment is reduced by 80% per ton of pulp.

        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 ，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.
