Single Screw Press

The CNBM Anyang Machinery Single Screw Press concentrator, also known as the spiral squeezing machine, is a dewatering device used for pulp processing. It effectively handles various pulp consistencies, ensuring uniform dryness and stable output rates of the concentrated pulp. The CNBM Anyang Machinery Single Screw Press concentrator is primarily used in the black liquor extraction process.

Single Screw Press concentrator consists mainly of a shell, a spiral shaft, and a water filtration drum.

In a single-screw press concentrator, the pulp is advanced by a spiral shaft with varying diameter and pitch, which exerts pressure on the pulp as the space gradually decreases in the direction of movement, achieving the goal of concentration.

CNBM Anyang Machinery Single Screw Press Advantages

1. Energy Efficient: Operates at low rotary speeds, leading to lower power consumption and reduced noise levels.

2. Innovative Design: The special structure prevents pulp from slipping, resulting in a high outlet pulp concentration.

3. High Dehydration Efficiency: Extracts up to 80% of black liquor from pulp, achieving excellent pulp dryness.

4. Versatile Applications: Suitable for various types of pulp, including straw, bamboo, bagasse, and wood pulp.

5. Odor and Spill Prevention: The shell design effectively prevents odor and black liquor spillover.

6. Mechanical Operation: Fully mechanical press dehydration requires no installation height, simplifying setup.
