Collection: Disc-type Ceramic Vacuum Filter

Product Overview

The Disc-Type Ceramic Vacuum Filter is a high-efficiency, energy-saving solid-liquid separation equipment that integrates microporous ceramic technology, ultrasonic cleaning, and PLC automatic control. It operates on the principle of vacuum suction combined with capillary action, achieving exceptional dewatering performance with minimal energy consumption.

This equipment is widely used in mining, metallurgy, chemical processing, environmental protection, and wastewater treatment industries for concentrate dewatering, tailings treatment, and various slurry filtration applications

How It Works

The filtration process follows five distinct stages:

Suction Stage – The ceramic filter plates are immersed in the slurry. Under vacuum pressure and capillary action, solid particles are attracted to the plate surfaces, forming a filter cake, while the filtrate passes through the micropores into the discharge system.

Washing Stage – As the filter cake rotates out of the slurry tank, spray washing is applied to remove impurities.

Drying Stage – The filter cake continues to be dewatered under high vacuum force, achieving low moisture content.

Discharge Stage – When the plates enter a non-vacuum zone, the scraper automatically removes the dry filter cake.

Backwash Stage – Industrial water or filtrate is flushed from the inside out to clean the micropores. After each cycle, ultrasonic waves combined with low-concentration acid ensure thorough regeneration of the ceramic plates.

Key Advantages

1. Superior Filtration Performance – With a high vacuum degree of -0.09 to -0.098MPa, the filter cake achieves very low moisture content. The filtrate contains less than 50ppm solids, allowing it to be recycled directly back into the system.

2. Exceptional Energy Savings – Compared to traditional filtration equipment such as drum filters or filter presses, energy consumption is reduced by more than 90%. Operating costs are substantially lower.

3. High Automation – The PLC and computer-integrated control system supports fully automatic operation. One-click start/stop, automatic valve control, and reduced labor requirements make it easy to operate.

4. Compact Design – The disc-type structure occupies minimal floor space while providing large filtration area. Installation and maintenance are straightforward.

5. Durable & Corrosion-Resistant – The stainless steel construction and white corundum ceramic plates offer excellent resistance to high temperatures, corrosion, and abrasion, ensuring long service life.

6. Advanced Cleaning System – The combination of ultrasonic and low-concentration acid cleaning maintains the ceramic plates at peak efficiency, reducing replacement frequency and maintenance costs.

Applications

The Disc-Type Ceramic Vacuum Filter is suitable for:

Mining & Mineral Processing – Dewatering of nonferrous and ferrous metal concentrates (copper, lead, zinc, iron), rare metal concentrates, and tailings

Chemical Industry – Filtration of oxides, electrolytic residues, leaching residues, and slag

Environmental Protection – Wastewater treatment, sludge dewatering, and waste acid treatment

Metallurgy – Processing of various slurries and suspensions
