Underwater Pelletizing

Why ECON:

• Push-button start – automatic, fast and safe
• The “freezing” of die holes can be prevented due to the thermal insulation technology
• Servo driven cutter hub control offers accuracy and machine safety
• Consistent pellet quality
• Integrated diverter valve controls resin in bypass
• No water bypass required, no water on floor
• Streamlined die provides no pressure build up, and minimum melt loss
• Compact unit, minimal space requirements, simple handling
• Pelletizer moves and functions as a complete unit
• Minimal energy consumption
• Low labor and maintenance costs

Polymer Diverter Valve:

• All thermoplastic materials can be processed in all sizes (micro, mini, standard)
• Highest process stability
• High-quality pellets
• Tailor-made solutions for your individual requirements
• Compact unit, minimal space requirements, simple handling
• Only 1 operator is needed
• Diverter valve for easy handling (included in the standard scope of supply)

Die Plate Unit:

• No “freezing” of die holes – provides constant high pellet quality
• Thermally insulated die plate – provides constant temperature through the carrier body & no overheating of the melt
• Reduced energy demand
• Die plate features easy handling, easy cleaning and quick change system

Cutting Chamber:

• Hydraulic locking system
• Easy to dismantle
• Easy to clean

Automatic Knife Adjustment Servo Drive:

• The servo motor controls the position and force of the knife carrier against the die plate.  The hydraulic locking system ensures proper adjustment and safe operation.
• Accurate knife adjustments by servo drive
• Automatic start sequence – fast and safe
• Online process monitoring of key process parameters for reproducible production processes
• Knives can be regrinded during production process

Water Treatment And Centrifugal Dryer:

Econ Water Treatment, EWT

• Pre-dewatering unit for best drying performance
• Clean process water will be recirculated – minimal water consumption
• Process water circle are separated to increase the lifetime of the heat exchanger
• Permanent control of the process water temperature

Econ Centrifugal Dryer, ECD

• Easy access for cleaning and inspection
• Highly wear resistant option for aggressive application
• Screen and rotor suitable for micro pellets
• rotor plates bolted for easy changing

EWT Optional Equipment:
