Mineral Processing Vacuum Disc Filters / Vacuum Ceramic Filter Disc

Mineral Processing Vacuum Disc Filters / Vacuum Ceramic Filter Disc

A vacuum ceramic filter is designed to separate liquids from solids for dewatering purposes. The device consists of a rotator, slurry tank, ceramic filter plate, distributor, discharge scraper, cleaning device, frame, agitating device, pipe system, vacuum system, automatic acid dosing system, automatic lubricating system, valve and discharge chute. The ceramic filters?are used to dewater mineral concentrates and pelletizing feed slurries.

Applications

The Vacuum Ceramic Disc Filters has been widely used in copper, iron, gold, silver, tin, aluminum, lead, zinc, nickel, palladium, cobalt, molybdenum, aluminum, phosphorus, coal, sulfur, silicon, quartz, mica, rare earth concentrate, tailings dewatering, Zinc Oxide, chemical industry lead oxide, zinc sulfide, electro slag, leaching slag, slag cement dehydration and environmental pollution as well as waste acid treatment. The fineness of materials is from -200 to -450 and a variety of superfine materials.

Features

1. High vacuum degree (vacuum degree -0.09~-0.098MPa), low moisture of cake

2. High filtration precision, solid content of filtrate<50ppm, which can be recycle used in the system.

3. Energy saving up to 90%, low energy consumption, low running cost

4. Filter cake cleaning system is installed

5. PLC and computer integrate with automatic valve control; high degree of automation and low labor intensity

6. LOW MOISTURE CONTENT OF CAKE. Average moisture content of concentrates is 7-8 %.

Work principle of the vacuum ceramic ?filter?

Driven by the main shaft, the filtering plate rotates to the direction of scraper. Under effect of vacuum system (vacuum pump, filtrate tank, distributor and relevant pipes), the filtering plate below slurry level absorbs the slurry while the filtering plate from slurry level to scraper makes the material (absorbed on it) dry. The filtrate goes into filtrate tank where from it is drained through discharge system (filtrate pump and relevant pipes).

When the filtering plate reaches the position of scraper, the cake is taken out by scraper and then given through discharge chute onto conveying belt. After discharge of material, the filtering plate is cleaned in the way of reverse flowing (cleaning takes place once after each circle of rotation). So a few of residue caused by clearance between filtering plate and scraper is cleaned out, and the function of filtering plate is restored during operation.
