Application
At present, it has been widely used in copper, iron, gold, silver, tin, aluminum, lead, zinc, nickel, cobalt, palladium, molybdenum, chromium, nickel, sulfur, phosphorus, coal, silicon, quartz, mica, tin and other concentrates , tailings dehydration, chemical industry zinc oxide, lead oxide, zinc sulfide, electrolytic slag, leaching slag, slag dehydration and environmental protection sewage sludge waste acid treatment, etc. Material fineness from -200 to -450 mesh and various ultra-fine materials.
Working principle
In industry, it refers to the process of separating solid and liquid through a medium to achieve solid-liquid separation, which is called filtration. Commonly used filter media in industry: granular media, fabric media, porous media ceramic media.
Use fabric media in coal preparation plants. Coal preparation plant vacuum filtration equipment can be divided into two categories: disc type vacuum filtration equipment and cylindrical vacuum filtration equipment. Mainly used to filter flotation clean coal, also can be used to filter slime or flotation tail coal. Filtration is a process of separating solid particles suspended in a liquid or gas.
Its basic principle: under the action of pressure difference, the liquid (or gas) in the suspension passes through the permeable medium (filter medium), and the solid particles are retained by the medium, thereby realizing the separation of liquid and solid.

Advantages.
1. The energy consumption of this filter is much lower than that of other filter equipment, and the energy consumption of other types of filters (including auxiliary equipment) is much higher than its energy consumption, and its energy consumption is equivalent to filter press In this way, the energy consumption of the machine is virtually saved.
2. Sensitivity to particle size, in theory, the smaller particle size of the ceramic filter can reach 1um. And some other equipment, such as belt filters, disc vacuum filters, etc., are difficult to adapt to very fine-grained materials, such as the disposal of metal tailings mentioned earlier, these equipments are quite inappropriate to dispose of!
3. The service life is quite long, and the wearing parts are relatively few. The ordinary filter can be used for 10 years, and the quality has been considered good. However, this filter can be used for a long time. The equipment with such a long service life, the cost performance is obvious.
4. The maintenance of the ceramic filter is relatively simple, and ordinary workers can learn it. Unlike some other very complicated equipment, if it is damaged, the manufacturer should come to repair it.
