Key applications of industrial filter cloth and industrial filter belts in pulp pressing in paper mills —— Empowering belt press filters to improve dewatering efficiency

In the papermaking industry, pulp dewatering is a key factor affecting production efficiency and paper quality. Belt press filters are widely used in pulp concentration and moisture control due to their continuous and efficient dewatering performance. As one of the core consumables, industrial filter cloth and industrial filter belts play an irreplaceable role in equipment operation. This article will focus on their specific applications in pulp pressing, exploring how to use high-quality filter cloths to solve production difficulties and help enterprises reduce costs and increase efficiency.

I. Challenges of pulp dewatering in paper mills

Pulp is the foundation of papermaking, and its dewatering process directly affects the quality of the finished paper. Traditional pulp concentration relies on gravity sedimentation, mechanical pressing, or vacuum suction, but these methods generally have the following problems:

  • Low dewatering efficiency : Especially for low-concentration pulp with high water content, it is difficult to achieve the preset dryness in a short time;
  • Serious filter cloth clogging : The pulp contains fine fibers, resins, adhesives, and other impurities, which easily cause filter cloth clogging;
  • Frequent filter belt replacement : High-intensity continuous operation requires extremely high wear resistance and peel resistance of the filter cloth;
  • High operating energy consumption : Poor pressing efficiency requires frequent backwashing, increasing operating costs.

In response to these challenges, choosing high-performance industrial filter cloths and filter belts has become a core element in improving the stability and efficiency of the overall pressing system.

II. Working principle of belt press filter and filter cloth requirements

The belt press filter mainly consists of two annular filter cloths (belts) that press the pulp through a series of rollers to achieve continuous dewatering. Typical work processes include:

  1. Pulp feeding : Pulp is evenly distributed between the filter cloths;
  2. Initial pressing stage : Part of the free water is removed by the pre-pressing roller;
  3. Medium and high pressure stages : Gradually increase the pressure through different roller sets to press out the bound water of the fibers;
  4. Discharging stage : The dewatered pulp cake is separated from the filter cloth, and the filter cloth is circulated and cleaned to enter the next cycle.

In this process, the function of the filter cloth is crucial:

  • Carries pulp and acts as a pressing carrier
  • Ensures rapid water passage and prevents fiber penetration
  • Maintains system tension and uniform pressing
  • Has good tensile strength and wear resistance to ensure long-term operation

III. Technical requirements of industrial filter cloth and filter belt in pulp pressing

For the actual operating conditions of paper mills, industrial filter cloths and belts need to meet the following performance standards:

1.  Precise pore size design

The pore size of the filter cloth needs to match the fiber particle size in the pulp. It should allow for rapid water permeability while preventing pulp leakage. Usually, 40–100 micrometer single-layer / double-layer filter cloth structure is used to effectively control filtration accuracy.

2.  Excellent mechanical properties

The filter cloth must operate under high tension and high-frequency roller pressure. Tensile strength and tear resistance are key factors, and high-tensile polyester fiber or modified polypropylene material is preferred.

3.  Surface smoothness and cake release

The surface of the filter cloth needs to be smooth enough to ensure even pulp distribution, while also having good cake release properties to avoid adhesion and filter cloth clogging.

4.  Easy to clean, resistant to chemical washing

The filter cloth needs to withstand frequent high-pressure washing and have good resistance to cleaning agents (such as alkaline cleaning solutions) to extend its service life.

IV. Xiamen Citius (Xiamen Citius) Industrial filter cloth solutions

As a leading brand in the field of filtration material technical textiles, Xiamen Citius (Xiamen Citius) Filtration Materials Technology Co., Ltd. has launched a number of filter cloth products specifically for belt press filters in the paper industry, with the following advantages:

Including single-layer plain weave, double-layer composite fabric, and spiral mesh belts, suitable for pulp treatment of different concentrations and fiber types.

✅   High-strength customized products

Through high-density weaving technology and reinforced edge treatment technology, the filter cloth has strong tension retention and is not easy to deform, suitable for long-term continuous pressing.

✅   High-efficiency water permeability and anti-clogging performance

The filter cloth surface is treated with an anti-stick process, combined with a longitudinal water guide design, effectively reducing the risk of blockage and extending the cloth replacement cycle.

✅   Full-process technical support

Xiamen Citius (Xiamen Citius) Provides filter cloth selection suggestions, equipment matching and debugging, filter cloth installation guidance and cleaning and maintenance solutions, truly achieving " One cloth, multiple solutions ”。

V. Typical Application Case Sharing

In a large-scale cultural paper enterprise, the original imported filter cloth was high in cost and unstable in lifespan, and problems such as filter cloth breakage and pulp cake adhesion easily occurred. Xiamen Citius (Xiamen Citius) team intervened and customized a high-permeability, high-peel double-layer pressing filter cloth ，The operation results show:

  • Filter cloth life improved 40% and above;
  • Dehydration efficiency increased by approximately 18% ，the pulp cake dryness is more stable;
  • The frequency of filter cloth replacement is reduced by half every month, saving a lot of labor and material costs.

This project has become a model of Xiamen Citius (Xiamen Citius) papermaking industry filter cloth service, and also reflects the strong competitiveness of domestic high-performance filter cloth in industrial applications.

VI. Conclusion

With the continuous improvement of environmental protection policies and paper quality standards, the pulp dehydration stage in paper mills is facing unprecedented optimization pressure. The application of belt press filter machines with high-performance filter cloths has become the key to achieving energy saving and emission reduction and improving product consistency. Xiamen Citius (Xiamen Citius) will continue to deepen the research and development and innovation of industrial filter fabrics to provide more efficient, stable and sustainable filtration solutions for the paper industry.
