Vacuum filter cloth for rotary drum and disc vacuum filtration systems

Machine Type

Vacuum Filter Fabrics

High-permeability filter cloths for vacuum disc filters, pan filters, and table filters. Designed for continuous operation and maximum dewatering efficiency.

About Vacuum Filters

Vacuum filters use negative pressure (typically 0.2–0.8 bar) to draw liquid through the filter cloth, forming a cake on the outside of the filter element. They are widely used for continuous, high-tonnage filtration in mining, chemical, and environmental applications.

Common configurations include disc filters (multiple rotating discs), pan filters (tilting pan segments), and table/indexing filters(horizontal rotating tables). Each type requires specific cloth properties for optimal cake formation and discharge.

Typical Applications

Iron Ore Concentrate
Copper Concentrate
Alumina (Bayer Process)
Phosphoric Acid / Gypsum
FGD Gypsum
Potash & Salt
Calcium Carbonate
Kaolin & Clay

Common Challenges

Vacuum filtration requires fabrics optimised for continuous operation under moderate vacuum pressure.

Permeability Control

Vacuum filters require precise air permeability to maintain cake formation speed. Too open and the cake is wet; too tight and throughput drops.

Cake Discharge

Disc and pan filters rely on gravity or blow-back for cake release. The cloth surface must promote clean discharge without residual buildup.

Abrasion at Edges

Cloth edges on disc filter sectors and pan filter segments are subject to mechanical wear. Reinforced edges and heat-sealed cuts extend cloth life.

Sector Fit

Disc filter sectors and pan segments require precisely shaped cloth panels. Accurate cutting and sewing prevents bypass and ensures uniform filtration.

Blinding Resistance

Fine mineral particles can progressively blind the fabric. Monofilament constructions and washable surfaces maintain long-term productivity.

Continuous Operation

Vacuum filters run 24/7 in mining and chemical plants. Fabric durability and consistent performance over thousands of hours is essential.
