Good quality PVC recycling granules extruder plastic extrusion line making machine
PVC Granulation Extrusion Line Description
1. The machine mainly produces PVC granules by hot cutting. The equipment is advanced, it has characteristic of strong universal and high output.
2. Conical double-screw extruder, very suitable to process PVC powder with high capacity
Pelletizing style: Hot-cutting on mould face, even cutting ensures good shape.
Auxiliary machine: Pellets cooling & classifying.
A wet extrusion process can be a continuous or a batch operation and typically consists of the following steps:
1. First the powders need to be dosed and homogenized as required by the recipe. All challenges related with these processes need to be dealt with. Before being delivered to the extrusion line, a reliable feeder with a mass flow pattern is required.
2. A wet extrusion line includes a mixing and kneading device that fulfils an important function. A liquid addition system will spray or drip water or an organic solvent onto the dry powder bed. As the kneading progresses, a homogeneous wet dough is formed.
1.High automationless labor waster plastic becomes granules directly after granulator
2.High quality granules with gas cylinder shape and smoothy and beautiful granule size is adjustment.
3. Volumetric feederscrew and granule cutter are controlled by inverter.
4.The barrel and screw are made of 38CrMoAl with surface Nitriding hardening treatment the the life-span is longer.
5. The gear box is hardend surface oil cooling onewhose weight is only half of that of soft surface gear box so it can suffer more wear-tear the lift span is 3-4 times longer and the loading capability is increased by 8--10 times higher.
6. The spaghetti will be cut directly by cutter and then the granules will be transported to the silo directly by air conveyor so no broken spaghetti will happen.
7.Water vent air vent and vacuum pump are equipped on the barrel to discharge the water and air so the granule quality is guaranteed.
