How to work
The double piston double working p[osition screen changer consists of the main body of the scren changer, the hydraulic power unit and electrical controlling pack.
1, in the normal condition, the two filter screen on the two slide bar are in the working position, the material melt is dvided into two chanel .
2, when the alarm device is alarming , remind us to change the screen, one piston is pushed out and the blocked screen will be replaced by a new one, then the slide bar is pushed back, the exhaust system begin to work at the same time.
3, then the other screen is replaced as the same way as before. this processing is cycled
Application
1. Used for the production of plate, sheet, cast film, pipe, granulation and so on.
2. Applicable to the production line of colossal, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture, filtering screen replacement available without machine halt.
