Product Description Recycling granulator strands die & continuous screen changerHigh output recycling extrusion machine continuous screen changerPlastic extrusion continuous screen changer with big areaLarge filtration area continuous screen changer with hydraulic stationDouble piston large capacity screen changer Continuous screen changer for plastic extruderPiston type continuous screen changer for plastic extrusion machineBenefits of thisGM-DP-L series continuous screen changer for plastic extruderIncreased productionReduced downtime & scrapLeak-free operationIncreased filtration areaReduced inlet pressuresAccurate, repeatable screen changesReduced maintenanceTechnical data1)The main body of the screen changerRaw material: Alloy steel(38CrMoAlA)Surface treatment: Nitriding treatmentDepth of Nitrated Layer: 0.40-0.70mmNitrided hardness: 950-1050HvFragility of nitration: Less than grade 1Flow channel treatment: Chrome platedDepth of chromium-plating: 0.05-0.1mmHardness of surface after chromium-plating: HV950HV2)Drive system: Hydraulic unit:3)Control systemElectrical controlling system: Warnning device, pressure and temperature transducer, are included, and this part is optional for customers.Working principle of this GM-DP-L series continuous screen changerAs the polymer melt enters the main body ofthe screen changer, the melt stream is divided equally and flows into the two channels, go through the two breaker plates, and the impurities are intercepted by the screen mesh, and when screen changing is required, one of the pistons with blocked screen pack is pushed out by hydraulic unit, and the other is still on the working position, we replace the fresh screen and then the piston with new screen is pushed into the working position, at this time, the air bleeding system also begin to work. The other piston screen change is the same with above. This type of continuous screen changer maintains a continuous melt flow.Benifits of this GM-DP-R series Extrusion screen pack changers continuous screen changer1, Eliminates line shutdown thus increasing production2, Leakage-free process3, Two breaker plates design increases filtration area compared to single breaker plate design4, Reduced downtime & scrap5, Reduced inlet pressure at extrusion die6, Reduced temperature variations in the melt ·7, Equiped with gas venting system8, Customized designThe structure and parameter data of GM-DP-L series Extrusion screen pack changers continuous screen changer1)The main body of the screen changerRaw material: Alloy steel(38CrMoAlA)Surface treatment: Nitriding treatmentDepth of Nitrated Layer: 0.40-0.70mmNitrided hardness: 950-1050HvFragility of nitration: Less than grade 1Flow channel treatment: Chrome platedDepth of chromium-plating: 0.05-0.1mmHardness of surface after chromium-plating: HV950HV2)Drive system: Hydraulic unit:Hydraulic unit3)Control systemElectrical controlling system: Warnning device, pressure and temperature transducer, are included, and this part is optional by customersApplications1.
