Vacuum Ceramic Filter is now proven the most energy-efficient and enviroment-friendly solid/liquid seperation device which produces an almost absolute vacuum resulting in very dry cake. It makes use of microporous ceramic plates through which no air will pass and only liquid could flow instead of filter cloth. The key to the ceramic filter is the porous ceramic filtration plate. The unique constructure of ceramic plate creates uniform micropores which establish the Capillary Action Effect creating an almost absolute vacuum ( less than 0.096Mpa) by which only liquid could flow through the plate and air canÆt pass through the plates. The ceramic filter has been widely used in the field of mining and metallurgy ( such as nonferrous metal mine and fine powder coal ), chemical processing, food, medicine and ceramics industry. The particle size of the slurry varies from 0.5¦m to 3mm, specially suitable for solid-liquid seperation of sand-character materials. The excellent de-watering function could also be gained for clay-character materials after adjusting the properties of slurry.

Operating Principle By utilizing the production technology of our patent, the filtering plate consisting of two pieces of cavity-structures which is produced mainly by using corundum-based material. The process include raw-material classification, cleaning & selecting, mixing, high-accuracy molding through die stamping, stage-wise high-temperature roasting, repetitious painting of function layer, cleaning & choosing, finalizing gluing, performance testing, packing and placing in storehouse. Repetitious roasting and layer-after-layer painting are adopted. Thus, the arrangement of pores (interior is big, exterior is small) is clear; The resistance at restoring of filtering plate's function is small; The cleaning of filtering plate is easy; The surface layer is of high strength and wear-resistant. The two pieces of cavity-structures are glued together using epoxy glue imported. The gluing is of high strength and is corrosion-resistant & wear-resistant. Features and Applications The ceramic filtering plates produced by our plant have been proved as successful in many beneficiation plants treating ores of copper, lead, zinc, iron, silver, sulfur, gold etc. The filtering plates are of high strength, easy to be cleaned for restoring of plate function. The maximum pressure for reverse cleaning reaches 0.3MPa that increases the performance of reverse cleaning & combined cleaning and raises remarkably the operation indexes of the filter. The service life of the filter exceeds 2 years that saves the investment & operation cost of customer.
Operating principle 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 off 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. After certain time (normally, 7 hours), it is necessary to clean the filtering plate by means of detergent (normally, it is nitric acid depending on characteristics of material) and ultrasonic. So the materials & foreign matters stopped in pores of filtering plate or absorbed on surface of filtering plate are cleaned out, and the function of filtering plate is restored during operation. The ceramic filter adopts PLC full-automatic control system. Both full-automatic operation and manual operation are possible to provide flexibility & convenience. Features and Applications Compared with traditional filters, it is featured in energy saving, high efficency, low production cost, high automation level, low power consumption, low moisture of filter cake. More importantly, the low suspended solids in filterate enables the ceramic filter easily meet the discharge standards, and customers can use it as circulation water without discharge it outside. It is extensively used for solid liquid separation in such industries as ore beneficiation, metallurgy, chemicals, paper making, coal, environmental protection and so on.
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 Tba
