We are offering The Dual-column dual- Plate Screen Changer. The dual-column/dual-plate double-position hydraulic screen changer is designed to work with two channels inside. It contains two screens that work at the same time: one screen works, while the other one is changed during the process of screen replacements, thus the replacement without machine halt is ensured and no interrupt of material fluid and of production will occur. Therefore, the screen changer meets the customers� requirement of higher productivity and better quality. Performance characteristics: 1�Special sealed structure design(self-owned patent), excellent effect, no material leakage for more than five years. 2�Dual channels for filtration, no need to stop the working machine when changing the screen, no production interrupt, and more efficiency and less energy consumption without any defective product. Especially appropriate for the production of cast film, plate and sheet. Application fields: 1 Used for the production of plate, sheet, cast film, pipe, granulation and so on. 2 Applicable to the production line of collosols, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture, filtering screen replacement available without machine halt.

We are offering new pulse backflush screen changer. the new high-pressure pulse backflush screen changer is the latest product developed by deao of self-owned chinese invention patent and international invention patent. There is no need to change the screen, but backflush of rapid pulse by little clean material in the machine. It is a symbol of internationally advanced technology, and is especially applicable for the machines of waste recycling and granulating, and direct waste processing. performance characteristics: 1�equipped with a strong pulse screen washing system (of self-owned patent ), screen washing online available, cleaning rate of the filtering screen up to 80%-95%, no production interrupt, more than 200 times of usage of the filtering screen (depending on the density of the screen). 2�filtering area from 365 cm2 to10000 cm2, initiative internationally (international patent), advanced technology, already put into practical application. application fields: 1�applicable to all the kinds of plastic products. 2�applicable to the production line of chemical fiber, rubber, collosol, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture.

We are offering automatic mesh belt screen changer. The automatic mesh belt screen changer is mainly composed of the screen changer, the heating and cooling system, and the electric control system. There is no need of manual operation of the screen changer because the material fluid inside flows by itself under the pressure caused by the melt production. performance characteristics: 1、automatical and continuous screen replacement without manual operation. 2、no fluctuation of material flow, no product deformation, excellent quality stability. 3、no waste product or waste material, and little material consumption occur when the screen changer works. application fields: mainly used for the production of pp, pe, abs, ps, pmma and other materials, and widely used for the cast film, sheet, plate, optical fiber, various drawings, granulators and other products of high quality and long production process.

We are offering new continuous screen changer. the new continuous screen changer and new four-screen recycling screen changer are especially applicable to foaming plate products such as xps, eps, epe and cast film. It ensures the screen changing without machine halt or production interrupt, which has been widely tested and verified in production practice. performance characteristics: 1ã��no need to stop the working machine when changing the screen, no material explosion, noiseless, no material leakage, or production interrupt while working. 2ã��this screen changer (self-owned patent ) is characterized by the convenience and safety to change the filtering screen with it. It is time-saving to install the filtering screen with the screen changer, and there is no need to manually disassemble the machine, adjust the para-position screen, or install the lock pact between different screens, thus the screen changing operation will be reduced by 90%. Application fields: 1ã��applicable to all kinds of plastic products. 2ã��applicable to the production line of chemical fiber, rubber, collosol, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture. technical data: type screen type (mm) heating power(kw) pressure (mpa) output (kg/h) dhbl-80 70ã�70 3 â�¤50 â�¤250 dhbl-100 100ã�90 5.6 â�¤50 â�¤450 dhbl-130 120ã�110 6.8 â�¤40 â�¤550 dhbl-150 140ã�130 8 â�¤40 â�¤900 dhbl-200 190ã�170 10 â�¤30 â�¤1500.
