Vacuum ceramic disc filter

Vacuum Ceramic Filter is a new type of Solid-liquid Separation machine which is featured in energy-saving, high efficiency, low production cost, high automation level, smooth operation, low power consumption, low moisture of filter cake, low suspended solid and appears in the 1980s. It's extensively used for solid-liquid separation in such industries as ore beneficiation, metallurgy, petro-chemicals, paper making, coal, environmental protection and so on.

Working principle: under the effects of pressure difference, as the slurry penetrates filter media, particles are blocked at the surface of filter media and filter cake is formed while liquid goes through the media and drained away so as to separate solid from liquid.

Vacuum Ceramic Disc Filters are the solid-liquid separation equipment, used to dewater mineral concentrates and pelletizing feed slurries. Micro porous ceramic discs replace conventional filter cloth.

Application area:

VCDFs are widely used in the beneficiation of such ore concentrates as Iron ores, Gold, Copper, Copper Sulfide, Nickel, Zinc, Lead, Molybdenum, Phosphorus, Sulfur, Quartz Sand, and Fluorite. A complete and up-to-date customers list will be provided upon request.

The ceramic filter consists of ceramic filtering plate, rotator, slurry tank, discharge scraper, distributor, agitating device, cleaning device (including ultrasonic cleaning & acid cleaning), frame, vacuum system, pipe system, filtrate discharge system, automatic lubricating system, automatic acid-dosing system, discharge chute, valve and PLC automatic control system (can be made as remote control system).

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 ), 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 ). 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.
