Ceramic vacuum disc filters are used widely for dewatering iron ore slurries in mining industry. The scale of iron production processes is typically very large which means that small changes in the operation of the filter can have a significant impact on the overall effectiveness of the process. Some of the variables that determine the performance of ceramic disc filters are the rotation speed of the disc, the level of slurry in the feed basin, the vacuum level applied during the filter cake formation and dewatering stages and the solid concentration as well as the temperature of the feed slurry.
Structure

Vacuum Ceramic Disc Filters 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 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.

Competitive Advantages of the product

1. High vacuum degree with maximum of -0.098MPa, low moisture of filter cake,
2. Low power and energy consumption, 10-20% of that of normal vacuum disc filters;
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;
4. Little pollution, environmentally friendly, safe and reliable;
5. Ceramic Filter Plate is long service life, easily install.
