Vacuum Disc Filter

Product Description

The vacuum disc filter provides continuous solid-liquid separation of concentrates and tailings using vacuum. Its key difference from other filters is uninterrupted operation. It delivers a low-moisture cake and recovers process water.

How It Works

Cloth-covered discs, driven through a gearbox and open gear, rotate in a tank filled with slurry. A vacuum pump creates a pressure difference across the filter cloth; solids form a cake on the cloth while water is drawn through. In the drying zone the cake is dewatered by vacuum and then discharged by back-blow and scrapers into a chute and onto a conveyor.

Applications

• Chromium, copper, zinc, gold and iron ore concentrates

• Feldspar, perlite, silica sand and quartz

• Coal dewatering

Advantages

• Continuous, steady operation with low vacuum loss

• Effective cake discharge with back-blow and scrapers

• Agitator keeps the slurry homogeneous

• Inverter speed control, automatic lubrication and cloth washing

• Easy operation

Technical Data

• Filtration area: up to 120 m²

• Liquid ring vacuum pump: 750 mmHg, up to 10,000 m³/h
