Blue Ocean granulating and pelletizing extrusion systems
Blue Ocean produces granulating and pelletizing systems for virgin and
secondary polymer raw materials. We supply different types
of pelletizing lines depending on
material’s type, output range and
special requirements of the customer.
We offer single screw extruders,
twin co-rotating and twin
counter-rotating screw extruders,
and also, unique triple co-rotating
screw extruders.
Main applications
Plasticizing, blending and mixing
Polymer recycling (PO and PVC pipes, PVC profiles, PET bottles, etc.)
Powder painting
  Reactive extrusion and degassing
Master batch preparation (fire retardant, color pigments, etc.)
Reinforcing (fiber glass, carbon fiber, etc.) and filling (wood and fiber, Talc, calcium carbonate, etc.) modification

Main advantages
- Complete compatibility of extruder with all sub-systems, simple operation
- Multilanguage computer control system
- High precision heating and cooling system
- DC or AC motors (Eurotherm, ABB inverters)
- Screw elements and shafts are designed by advanced CAD method, barrels are precisely machined by five-axes machining center
- High torque transmitting capacity
- Low noise

Blue Ocean triple co-rotating screw extruders
Blue Ocean triple co-rotating screw extruder adopts co-rotating, parallel, equal screw diameter triple screw construction. With smaller screw length/diameter ratio, machine can achieve same mixing and dispersing effect as twin screw extruder with larger L/D ratio (twice higher output at same screw diameter); degassing efficiency is also enhanced greatly due to the increase of specific surface area and surface turnover rate. Screw elements have unique self-cleaning effect. The feed entrance of feed barrel is specially designed to ensure the input ability levelness, which completely match high production rate of the machine.

 

 


Main advantages

- PCC (programmable computer control) system
- High output, high filling, high dispersing
- Low energy consumption
- Wide application scope

Main applications
Blending modification and filling reinforcement with strict dispersing requirements and large loading levels (PO and engineering plastics modification, etc.)
Master batch preparation (fire retardant, color pigments, etc.)
In-line compounding and reinforcing
