Disc Vacuum Filter

Introduction

Disc Vacuum Filter is a high-efficiency continuous solid-liquid separation and dewatering system designed for fine-particle materials and mineral slurries. It uses vacuum negative pressure to achieve efficient filtration and low-moisture filter cake formation. With continuous operation, automatic cloth cleaning and back-blow cake discharge, it is ideal for large-scale and demanding dewatering applications.

Working Principle

The filter discs rotate continuously in the slurry tank. Vacuum pressure draws liquid through the filter cloth while solid particles form a filter cake on the disc surface. As the disc enters the dewatering zone, continuous vacuum suction removes more moisture. The filter cake is then discharged by reverse air blow, while the filter cloth is automatically cleaned for the next filtration cycle.

Advantages Over Conventional Filtration Equipment

Continuous Operation — Unlike batch-type filter presses, it enables uninterrupted 24/7 filtration and dewatering.
Higher Processing Capacity — Multi-disc modular design delivers high throughput for large-scale production.
Lower Cake Moisture — Optimized vacuum dewatering achieves consistent 8%–12% moisture in suitable applications.
Less Manual Labor — Automatic filtration, cake discharge, cloth cleaning and lubrication reduce operator intervention.
Better Durability — Wear-resistant materials and optimized sealing make it suitable for high-density, highly abrasive slurries.
Lower Maintenance Cost — Modular construction allows quick replacement and convenient maintenance of key components.
