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

Ceramic foam filters Arffil ceramic foam filters are characterized as high permeation rate, good strength and thermal shock resistance, stable quality and without loosing impurity in high temperature either in big size or small ppi products. Advantages compared with traditional filtering materials: Thermal and chemical stability in high temperatureücavoiding the chemical reaction with the filtered molten metal. High porosity and good mechanical strength in elevate temperature due to its pure ceramic composite. Full open cell without loosing ceramic particles or powders (snowing) during filtrating. Low head loss, easy operation, energy save. Make metal flow reposeful and avoid the sputtering and backset, this increases the surface quality of the cast, prevent the pore disfigurement and finally lower down the waster rate. Box quantity depends on the filters's dimensions
