In recent years, belt press filter machines have been widely used as mature equipment for the solid-liquid separation of polishing slurry. In this system, the seemingly "ordinary" filter cloth actually plays a core role in the success or failure of the entire dehydration system. This article will analyze the application logic, performance design, and customization direction of filter cloth in belt press filter machines, starting from the characteristics of polishing slurry in the ceramic industry. Combining the technical experience and application results of Xiamen Citius, it will outline a modern industrial picture of "microscopic materials affecting macroscopic system efficiency".

Salt is one of humanity's oldest chemical products and an important pillar of the national basic industry. In modern industrialized salt production, the raw brine often contains various soluble and insoluble impurities, especially calcium carbonate (CaCO₃) and calcium sulfate (CaSO₄) and other precipitable inorganic salts. If these impurities are not sufficiently removed in the pretreatment stage, it will not only affect the purity of the finished salt but may also cause scaling and blockage in downstream evaporation and crystallization equipment, leading to operational risks.

In the modern sand and gravel industry, especially in the production of manufactured sand and river dredging and sand washing plants, environmental regulations are becoming increasingly stringent, and "mud-water separation" efficiency has become a key indicator of sustainable development for enterprises. Faced with high water content, high fine particle content, and high throughput sand washing sludge, belt press filter machines are gradually becoming the mainstream solid-liquid separation equipment. In this system, the seemingly ordinary but highly technical industrial filter cloth and filter mesh play a decisive role.

With the widespread use of manufactured sand in urban infrastructure and commercial concrete, the demand for supporting environmental protection measures is also increasing. Especially during the sand washing process, the discharge of large amounts of muddy wastewater and fine sediment not only increases environmental pressure but also affects subsequent water recycling and site management. How to efficiently and economically separate solids and liquids and dewater the sand washing sludge has become a problem that sand and gravel companies must face.

Filter cloth selection: An indispensable key step in solid-liquid separation
As a key component in the solid-liquid separation process of filter presses, the performance of filter cloth directly affects the filtration effect, filter cake quality, and production efficiency. Filter cloth selection should comprehensively consider three aspects: material type, yarn type, and weaving structure. Common filter cloth materials such as polyester, polypropylene, nylon, and vinylon each have different acid and alkali resistance, temperature resistance, and mechanical strength characteristics; yarn types such as monofilament, multifilament, and staple fiber affect the surface characteristics and particle retention efficiency of the filter cloth; weaving structures (plain weave, twill weave, satin weave) further determine the permeability and wear resistance of the filter cloth. Based on different operating conditions, such as acidic or alkaline environments, particle size requirements, filter cake removal difficulty, and wear resistance needs, scientifically and reasonably selecting filter cloth can significantly improve the efficiency and economy of solid-liquid separation, extend the service life of equipment, and reduce operating costs.
