The disc vacuum filter features optimized filter sectors for fast dewatering, delivering filter cake with low moisture and uniform thickness for easy stacking, transportation and material recovery.
Multi‑layer sealing design effectively prevents slurry leakage and reduces equipment failure rate.
It boasts long service life and lowers overall operating costs.
The disc vacuum filter is a continuous high-efficiency solid-liquid separation and dewatering machine optimized for fine-particle mineral and industrial material processing. It overcomes common drawbacks of traditional filter presses, including intermittent batch operation, high energy consumption, frequent failures and high operating costs. Fully upgraded for harsh working conditions of metal ores featuring high density, fast sedimentation and strong slurry erosion, it delivers greatly improved stability and dewatering performance. The disc vacuum filter can run fully automatically 24/7 without stopping. this mineral dewatering machine adopts high vacuum negative pressure for low‑moisture filter cake and clear recyclable filtrate. Equipped with non‑stop online filter cloth cleaning, it maintains stable output without capacity loss. Featuring cost‑effective investment and high processing efficiency, it serves as a mainstream dewatering solution for mineral processing, tailings dry stacking, industrial sludge treatment, building‑material and chemical industries.
Disc vacuum filter is a solid-liquid separation equipment. The filter disc is driven by a motor through a reducer and an open gear transmission, which rotates at a certain speed in a tank filled with slurry. In the adsorption zone, the solid material is adsorbed on the filter medium (flter cloth) by the pressure difference formed by the vacuum pump on both sides of the filter medium forming a filter cake. When this part of the filter disc separates from the slurry and enters the dewatering zone, the filter cake is continuously separated from the water by the vacuum suction force, and is discharged through the filtrate pipe and distribution head, thus drying the filter cake. After passing through the unloading area, the filter cake is unloaded from the flter disc by the reverse air blower and falls into the discharge chute, which is then transported away by the ore collection conveyor or other vehicles. The entire homework process is continuous and on going.
1. The equipment adopts integrated modular design and manufacturing, and the disassembly, maintenance, and replacement of each component are convenient
2. The dewatering holes of the filter fan and filter plate are evenly distributed, with a reasonable porosity and large rib size. They are made of high-strength engineering plastics, which increase the service life by 1-1.5 times.
3. The filtration area of the filtrate tube is large, and the abdominal volume of thedistribution head is large, which improves the pumping rate and filtrate discharge effect.
4. The filter cloth is made of wear-resistant nylon, single or double filament material, which has a high cake removal rate and is not easily clogged, with a long service life.
5. Each lubrication part adopts multi-point dry oil pump for centralized multi-point automatic lubrication, saving labor. its good dewatering effect.slurry leakage.
6. The filter cloth is equipped with an automatic cleaning device, which maintains.
7. Adopting horizontal forced high-speed mixing, using magnets at the shaft end, graphite packing, and triple sealing with water pressure difference to prevent.
8. Drive with variable frequency and speed, adjust according to the concentration and flow rate of the material to achieve the desired working effect.
9. The guide plate, guide wheel, and filter fan pressure plate are all made of high- quality polymer materials, which are lightweight, high-strength, and easy to replace.
10. The inner lining of the filtrate tube is made of high-strength wear-resistant ceramics, which increases the service life by more than 10 times.
11. The friction plate is made of boron phosphorus cast iron, which combines rigidity and flexibility, and has good sealing performance. 12. Remove the lower flange from the interface between the filtrate tube and the filter fan, and use mold positioning for direct welding, reducing 90% of possible air leakage points.
13. Each filter disc is composed of several filter fans, each of which is an independent filtering unit, making the discharge more thorough and the moisture content lower.
14. The filter cake is discharged using a pulse back blowing method, with the back blowing air coming from the vacuum pump outlet or Roots blower.
15. High degree of automation, capable of continuous feeding, filtering, and unloading for 24 hours without interruption; Energy saving, environmentally friendly, and free from secondary pollution.
This industrial vacuum disc filter handles solid‑liquid separation and dewatering for various fine‑particle materials. Typical applications cover metal ore concentrate dewatering & tailings dry stacking, non‑metallic mineral filtration, industrial & mineral‑processing sludge dewatering, cement and building‑material powder treatment, metallurgical and chemical slurry processing. It performs exceptionally well for high‑density, fast‑settling mineral slurries, and acts as an efficient dewatering option for mineral processing plants and environmental‑protection projects.
