PET paving tile production line to mix 30% PET fakes and 70% sand to make different kinds of pavement bricks and tiles. The extruder is mainly for plastic composite plastic sand.
Material is mixed by mixer and come into the rotary charger, Then rotary charger will send the material into the extruder, After the extrusion, the material will be mixed together equaly.
Many kinds of plastic materials can be processed directly without degassing.After extrusion the material can be used to make pavement blocks or tiles.
Heating screw extruder for plastic sand composition from waste plastic HDPE LDPE PP PVC PETand sand
How the machine works:
1. First you can weigth each material, like we use waste PET flakes - 30 kg,filler - 25 kg, Sand - 70 kg, Or you also can add some other additives like pigment. And you can use up to your requirement, PP ,PE PVC all are possible. .
2. Each material put into the mixer and the mixer will mix all of these material for about 5-10mins, and then open the mouth on the mixer, the material will come down into the hopper of screw loader.
3. Screw loader send the mixed material into the hopper of feeder on the extruder , When the feeder is full, the screw loader will stop by itself. If there is no material in the hopper, you can restart the screw loader.
4. Then material is plasticised and degassed in the extruder screw, next the material will be plasticised and melt together in the screw, with the extrusion, the material come out.
5. After weigth the block material, then hydraulic pressre can make each kinds of blocks with its mold design.
