  • Brief Introduction

    RX precise vacuum filter combines mechanical and electric machine, ceramic tube with micro-hole and ultra-

    sound to separate solid and liquid depending on vacuum suction and capillary function with high efficiency and

    energy-saving equipment; they are widely used for mine, metallurgy, chemical industry and environmental protec-

    tion industry.

    Working Principle

    Slurry-sucking district: screen plate which is dipped in the slurry will be formed into one layer of filter cake

    under capillary function and vacuum pressure, the liquid will enter into distributing valve and drain tan via screen


    Cleaning district: spray the filter cake after coming out of the hopper.

    Drying District: filter cake will be dehydrated under high vacuum function.

    Discharging district: the scraper will discharge the materials automatically under non-vacuum state.

    Back-cleaning district: Ceramic plates will be cleaned from inner part to outer part by industrial water or

    filtrate which is passed through distributing valve.Then the jam left on the micro-hole is cleaned. After one period

    of application, ceramic board should be cleaned with ultrasonic and acid with low concentration to let the board

    work with high efficiency.

  • Introduction about RX Series of Ceramic Plates

    RX whole ceramic filter plate is developed by our company through cooperating with several ceramic institutes

    and absorbing foreign advanced technology, we provide our product to have high efficiency and save energy in an

    environmentally friendly way. This production is mainly used for dehydration of concentrate minerals such as Gold,

    Silver, Copper, Iron, Tin, Cobalt, Molybdenum, Chrome, Sulfur, Phosphorus, Aluminum, Zinc, Nickel and so on.

    Also it fits for treatment of sewage and acid waste. The applicable range of materials is from -200mesh (covers 50%

    to 400mesh (covers 90%), and including micron materials. Our products have successfully won our user's confidence

    due to its high separation rate, high separation precision, high operation efficiency and excellent technical economic

    index, as well as extensive adaptability.

    Ceramic Filter Plate is a kind of large porous ceramic disc which is fired by inorganic membrane making

    technology. It has following characteristics: large filter area, high intensity and even aperture. Besides, the aperture

    size can be adjusted according to actual demands. The basic material is alumina, it has good resistance to acid and

    alkali. After a period of application, the ceramic filter board can be cleaned by cycle reverse cleaning, ultrasonic and

    chemical cleaning agent and so on, to let the boards work with high efficiency.

    Regarding firing process, traditionally the ceramic plate is consisted of two layers of plates which are glued

    together to form inner channels. But after long term running, the glue will block the pores to cause "flower spots" on

    the surface of the plates.

    Considering this phenomenon, our company independently developed a new technology. Now the ceramic plate

    is poured in one mould as a wholeWe select a kind of special material, when firing under high temperature, this

    material is volatilized to form the inner channels.Thus, the "flower spots" will be avoided, also the ceramic plates

    will have higher strength and not easy to be broken.

    Recently, for mine production decreased obviously after several times ore absorption, our company developed a

    new type of membrane surface. The porosity of the new membrane can reach 55.60%, the microporous inwalls are

    smooth, and the tiny particles can pass smoothly in ore absorption process, so the jams will be reduced better.

    Meanwhile, after long-term use and backwash, the regeneration ability is obvious, the service life is longer, so as to

    achieve the maximum efficiency of plate surface, and improve the output.

  • RX 8m2 ceramic filter plate is first developed by our company through combining with foreign advanced

    design idea. This plate is a large area ceramic vacuum filter plate of low energy consumption and

    environmentally, which is suitable for 144m2, 204m2 and 240m2 ceramic vacuum filters. The 8m2 plate still

    follows the new technology of our company, fully meet the use demand of large area ceramic filters, and ensure

    the normal operation of equipments. The launch of the 8m2 ceramic filter plate (12m2 each circle) provides the

    possibility and guarantee for manufacturing ceramic vacuum filters in China. At present, this 8m2 plate has

    been widely used and recognized in Chile, Australia, Canada and other countries and regions. Now our

    company is manufacturing 240m2 filtering equipment through cooperating with Longhai company, to meet the

    market demand.

    Working Principle and Application Diagram

    Firstly the ceramic screen plates which are dipped in the slurry will form a thick layer filter cake on the surface

    of plates under vacuum pressure. The filtrate will go through the plates and then enter into distributing valve, finally

    arrive in the vacuum barrel. In the dry district, the filter cake will be dehydrated under high vacuum function to

    make it further dry
