PGT Disc Filter

PGT Series Disc Vacuum Filter for Metal Ores

The PGT series disc vacuum filter for metal ores fully incorporates the advantages of similar foreign products. Addressing the characteristics of metal minerals—such as high density, rapid settling, and strong impact force of solid particles on the filtrate pipes—the design has been optimized for overall performance and reliability of all components. This ensures excellent dewatering performance in solid-liquid separation of metal minerals. Successful field applications by users have proven that its main technical indicators and performance have reached advanced domestic and international levels.

Main Features

1. Filter Plates: Evenly distributed dewatering holes, reasonable hole ratio, large rib dimensions. Made of high-strength engineering plastic, service life increased by 1–1.5 times.

2. Filtrate Tubes & Distribution Head: Large filtration area and large cavity area of the distribution head improve vacuum extraction rate and filtrate discharge efficiency.

3. Filter Cloth: Wear-resistant nylon monofilament or double-layer multifilament filter cloth improves dewatering efficiency, resists clogging, and extends service life.

4. Automatic Lubrication: Multi-point dry oil pump for centralized automatic lubrication.

5. Automatic Cloth Cleaning System: Maintains good dewatering performance.

6. Horizontal Forced Variable Speed Agitator: Triple sealing at the shaft end using rubber, graphite packing, and water pressure differential ensures no slurry leakage.

7. Main Drive with Stepless Speed Control: Adjustable based on material concentration and flow rate (using AC variable speed motor or VFD) to achieve ideal operating performance.

8. Disc Construction: Each disc consists of 20 filter segments, improving filtration process control and ensuring uniform cake thickness.

9. Friction Plates: Made of special wear-resistant boron cast iron, combining rigidity and flexibility for good sealing and long service life.

10. Filtrate Pipes: High-strength wear-resistant ceramic composite steel pipes, service life increased by more than 10 times.

11. Filtrate Pipe to Filter Segment Connection: Removes upper and lower flanges, using mold-positioned direct welding, reducing potential air leakage points by 90%.
