eprotec 83% CaCO3
In January 2007, eprotec extrusion technology AG (CH-8105 Regensdorf www.eprotec-extrusion.com) introduced a melt pump for a filter percentage of 83% CaCO3 in PP/PELD compounding.
For the time being, it is the highest filter percentage in gear pump supported extrusion. A performance of 3.5t/h is another milestone in the success story of the Swiss company.
Therewith eprotec continues strengthening its reputation as a leading supplier of melt pumps in high speed extrusion, DSD recycling and fibre glass/BaSo4 compounding.
6.4 tons/h PVC with 50-70% limestone
2014 the melt-X 80 was successfully put into operation for 4.2 t/h for the sensitive compound with 50-70% CaCO3. The eprotec melt pump melt-X 80 is used for process stability and precise pressure build-up in the application with a Co-rotating twin-screw extruder. With optimization of the upstream equipment, the plant produces since 2015 6.4 t/h micro pellets with 50-70% limestone. The second line for 6.4 t/h was put into operation in summer of 2016.
