Beijing Shengnuo Industrial Mining Technology Co.

A kind 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. It’s extensively used for solid-liquid separation in such industries as ore beneficiation, metallurgy, chemicals, paper making, coal, environmental protection and so on.<br><br>Vacuum Ceramic Disc Filters are the solid-liquid separation equipment, used to dewater mineral concentrates and pelletize feed slurries. Micro porous ceramic discs replace conventional filter cloth. <br><br>Application area:<br>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.<br><br>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).<br> <br>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. <br> <br>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.<br> <br>The ceramic filter adopts PLC full-automatic control system. Both full-automatic operation and manual operation are possible to provide flexibility & convenience. <br><br>Important Features of Our Vacuum Ceramic Disc Filter: <br>1. High vacuum degree with maximum of -0.098Mpa, low moisture of filter cake, normally 2-4% lower than moisture of the cake by traditional filters.<br>2. Low power and energy consumption, 10-20% of that of traditional filters.<br>3. Clear and transparent filtrates. Solid content is normally lower than 21mg/L and filtrate can be recycled or disposed of without harm to the environment.<br>4. Little pollution, environmentally friendly, safe and reliable.<br>5. Ceramic Filter Plate is long service life, easily replaced and doesn’t require intensive labor work.<br>6. Dewatering cost if normally 18.8%-40.1% of that of traditional filters.<br>7. Automatic and continuous operation, low maintenance cost, high filtrate efficiency.<br>8. Lower metal loss and higher metal recovery.<br><br>
