Major characteristics:

• The cramming unit provides positive and continuous feeding of poor flowing dry blends
• The 3-phase AC drive of the crammer feeder allows for metered, packed or starved feed
• Different feeder systems permit the optimum configuration of the selected extruder for the materials to be processed
  
  

Metering and stuffing combination:

• Horizontal twin-screw metering unit with variable speed
• Vertical cramming screw with constant speed
• Speed synchronization of all drives with the main extruder

System benefits:

• Wide range of materials
• Agitator in storage bin prevents bridging
• Self-cleaning metering screws
• Quick cleaning at color changes due to hinged construction
