The Leistritz Twin Screw Extrusion Workshop provides an in-depth review of twin
screw extrusion theory and practices. A unique facet of the program is that
classroom training is combined with "hands-on" operating experience. A partial list
of topics is as follows:
• Twin screw extruder theory and design • Direct extrusion for sheet, film, fibers
and profiles
• Screw design and process techniques for mixing and devolatilization • Process considerations for reactive
extrusion
• Applications for co-rotation and
counterrotation • Troubleshooting twin screw extruders
and systems
• Sequencing of multi-stage process
operations • Control and monitoring options
• Scale-up of the twin screw extrusion
process • Screw assembly and disassembly
• Feeder and materials handling for
pellets, powders and liquids • Machine maintenance
• Pelletizing options: strand cut,
water ring, and underwater • Twin screw extrusion applied to
medical and pharmaceutical applications
"Hands-on" demonstrations at Leistritz NJ process laboratory:
• Hands-on” demonstrations at Leistritz NJ process Co-rotating and
counterrotating twin screw extruders
w/ up to 1200+ screws rpm •
