Disc Vacuum Filter
Capacity: 0.85-1.2 t/h·m² (Different material processing capacity is different)
Application: It is suitable for fine material filtration and dehydration of fine tailings and non-ferrous metal concentrates in mineral processing plants and can also be used for sewage, sludge, and solid-liquid separation processing in metallurgy, chemical industry, petroleum, and sewage treatment industutry.
Introduction: Our disc vacuum filter adopts a polyurethane or industrial polypropylene filter plate, which is lightweight and corrosion-resistant. It is an excellent filter equipment for tailings filtration and dehydration in non-ferrous metal and non-metal beneficiation. Aiming at the characteristics of the high density of metal minerals, fast settling, and strong impact of filtrate-containing solid particles on the filter tube, JXSC has optimized the overall performance and reliability of each component of the vacuum disc filter. It can efficiently separate the solid particles from the slurry, fully guarantee the excellent dehydration index of the metal minerals in the solid-liquid separation and improve the ore grade.
We also provide ceramic filters, which use microporous ceramics as filter media, saving more than 90% energy consumption. The panel is covered with 3-5 micron pores, more suitable for tailings or finer mineral powder dehydration. It can resist almost all temperatures and has a long service life. Both are a new type of high-efficiency and energy-saving filter equipment.

Working principle of Disc Vacuum Filter
The components of the disc vacuum filter include filter disc, vacuum system, suspended matter supply system, filter cake cleaning system and slag discharge system, etc. Filter discs typically consist of flat or uneven filter media (usually fine-pore filter cloth or membrane) that trap solid particles or suspended matter while allowing liquid to pass through. Start spinning at low speed to ensure the liquid is evenly coated on the filter media when operating. The material flows into the center of the filter disc from the feed pipe, and the solid particles remain on the surface of the filter medium to form a filter cake. At the same time, the clarified liquid enters the collecting tank or pipeline below through the filter medium. Through the rotation of the filter disc, the filter cake can be continuously formed and removed, realizing a continuous solid-liquid separation process.

Combined with some defects of the existing equipment, according to the particularity of the mining industry, JXSC redesigned a new type of filter fan and other durable accessories.
1. Filter blade:
- The surface is smooth, the dehydration holes are evenly distributed, the porosity is reasonable, and the edges of the filter fan and ribs are rounded. It not only improves the dehydration rate but also prolongs the service life of the filter cloth.
- The head of the filter fan is chamfered and has high strength, and the bottom has reinforcing ribs, which are not easily damaged or broken during assembly and disassembly.
- The angle between the rib direction and the center line of the filter fan is more reasonable, and the fluid resistance is small. The effective area of the filter fan is large, which improves the processing capacity of the filter.
- The wall thickness of the filter fan is increased by 1/3 compared with ordinary ones, and the average service life is extended by 1.5-2 times.
2. Main shaft and filter tube:
a. The filter tube and the shaft head are made of high-strength wear-resistant seamless steel tube, the tube wall is thick, not easy to wear, and the service life is increased by more than two to three times.
b. Each filter fan has a pressure plate, and the two ends of the pressure plate are respectively pressed with stainless steel bolts and nuts, which are not easy to rust, easy to replace the filter cloth, and greatly reduce the labor intensity.
3. We adopt the following mixing device to achieve the ideal effect and users have widely praised it.
a. Add permanent magnets – to prevent mineral powder from entering the stirring sleeve;
b. Adopt water seal;
c. Use packing seal;
d. The shaft is sealed with a skeleton sealing ring;
e. The surface of the shaft is chrome-plated, which is not easy to rust;
4. Other accessories:
- Corundum polymer wear-resistant coating is used in the tank below the stirring shaft to prevent the wear of the steel plate in the tank.
- Using special wear-resistant boron-phosphorus cast iron, combining rigidity and softness, good sealing effect, and extending the service life by 2-3 times.
- Adopt dry oil pump centralized multi-point automatic lubrication to ensure the regular operation of the equipment. The filter cloth is cleaned by an automatic cleaning device, maintaining a good dehydration effect.
- Adopts frequency conversion speed regulation to adjust the concentration and flow of materials to achieve ideal working results.
