ZSLX Series Double Helix Cylinder Press

This product is mainly used for black liquor extraction of digested pulp and pulp concentration and washing of recycled waste paper. After years of production and use, it has advanced structure and excellent performance. This product is a new type of equipment developed by our factory based on the introduction of advanced technology and combined with the actual situation of China’s paper industry. Its characteristics are:

1. Adopting synchronous reverse double helix volume change for compression and extrusion, the slurry is dehydrated, and the equipment will not produce slurry slipping. The outlet concentration is high, and the fiber loss rate is low.

2. This product has a simple equipment structure, convenient operation, and low power consumption.

3. Small footprint and convenient installation.

4. Adopting a variable speed motor drive can be suitable for production in different situations.

Working Principle

Adjust the slurry concentration to 8% -10%. Entering the inlet of the double helix Cylinder Press, the pulp has a squeezing effect inside the Cylinder Press, causing the water or black liquor in the pulp to be squeezed out, achieving the purpose of concentration or black liquor extraction. At the same time, due to the squeezing of the slurry, it also produces a certain degree of fibrosis. The double screw helix Cylinder Press adopts a synchronous reverse double screw rod variable pitch rotation structure, effectively eliminating the phenomenon of pulp slipping and causing the pulp to undergo periodic flipping in the cavity, resulting in periodic squeezing and diffusion of black liquid between fibers and fiber cells. The washing quality is good, the pulp concentration is high, and the fiber loss is small.

Technical Characteristics

1. Adopting a synchronous reverse variable pitch double helix structure, the phenomenon of slurry slipping inside the equipment is eliminated; Make the equipment have a large production capacity, a high extraction rate of black liquor, and a high concentration of extracted black liquor;

2. Due to the double helix structure, the extrusion capacity is large, and the fiber dispersion is strong, and the washing quality is high after the double helix periodic extrusion Diffusion;

3. Adopting a stainless steel sieve plate structure, the opening rate is increased, the pore size is reduced, and fiber loss is reduced;

4. The equipment structure is simple, easy to maintain and manage;

5. Adopting a speed regulating motor, the working condition can be changed at any time;

6. This device occupies a small area and is easy to install.
