plastic melt filtration system-automatic mesh belt screen changer
Automatic mesh belt screen changer
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.
1,performance characteristics:
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.
How to work
How to work
The screen moves across the flow of plastic melt and a fresh screen enters as the spent filter screen exits; removing the impurities from the raw material. The belt screen changer is fitted between the end flange of the extruder and the die. A cassette holding a roll of screen filter is attached to the side of the belt screen changer block. The controlling box of belt screen changer is equipped with a pressure sensor, and a pressure warning device, when the pressure is raise to the preset , it will automatically alarm, at the same time, the screen is replaced automatically. And the cooling system begin to work , the impurity is cooled and moved out with the filter screen.
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 .
Commissioning
At the requirement of customer, seller should send technicians to install and debug the screen changer to the die at site of Buyers, Travelling expenses and accommodation fee should be borne by Buyers.
12 months with proper operation by user, all the spare parts shall be replaced free of charge under guarantee period, fee for transportation and packing will be borne by users.
