Two Stage Pelletizer
Two stage pelletizer for different plastic compound.
Two stage pelletizer intro
Double stage extruder series is a combination of single screw and twin screw.
Low screw speed can avoid over shear force phenomenon, internal screw cooling system can avoid overheating and strong heat exchange capacity.
The two are functionally separate, allowing for more flexible and predictable mixing processes and temperature control.
Two-stage extruders are mainly used for the blending of heat-sensitive and shear-sensitive materials.
The double-step structure and the building block structure of the processing section make this model suitable for the processing of a variety of materials.
Such as: PVC, XLPE cable material, soft PVC medical material, hard PVC, EVA foam sole material, PE low smoke halogen-free fuel and so on.
Of course, it can also be used for granulation of other materials
| Model | Diameter(mm) | Motor(kW) | Output(kg/hr) |
| MTS 50-120 | 50.5/120 | 75/45 | 250-400 |
| MTS 65-150 | 62.4/150 | 90/55 | 500~700 |
| MTS 75-180 | 71/180 | 132/75 | 800~1200 |
In addition, two stage extruder can also produce highly filled calcium carbonate/
Barium Sulfate masterbatches, ect. And other plastic granules compound.
Basic cable formula:
PE/PVC compounds are widely used in wires and cables for insulation and sheathing purposes. In fact, polyethylene compounds are among the most common forms of plastics. Polyethylene is a thermoplastic polymer consisting of long hydrocarbon chains of the base monomer (C2H4) and our PE compounds are generally based on polyethylene or co-polymers of polyethylene suitably modified to client specifications.
LDPE/LLDPE/MDPE/HDPE + color pigment/carbon black 2-5% + additives
PVC 60% + DOP 20% + Calcined Clay 10-20% + CaCO3 0-10% + Heating Stabilizer + Additives
The first stage is co-rotating parallel twin screw extruder for dispersion and distribution.
The second stage is single screw extruder for cooling and pelletizing.
There are many forms of cable material composite, each material using a different method. We pursue the most practical, efficient process.
