pelletiser is a compact model designed for laboratory applications
control up to ten ECONia lines from one point while an inline monitoring system — ECON Pellet Vision — monitors pellet quality. If the system detects any deviations, the parameters are adjusted automatically to maintain pellet quality and minimise production of off-spec material.
Targeting LFTs Last year, Germany’s ips Intelligent Pelletizing Solutions, which produces strand and underwater pelletisers, introduced a system for production of long-fibre reinforced thermoplastics (LFT) pellets. It worked on the development together with the Cetex Institut and the Institut für Textil- und Verarbeitungs- maschinen (Institute for Textile and Processing Machines) at the Technical University of Chemnitz. The initiative was promoted by the Zentrale Innova- tionsprogramm Mittelstand ZIM (Central Innovation Program for Medium-Sized Businesses ZIM). The company will offer the LFT HP system on a
turnkey basis. It says the technology will produce high-quality LFT pellets using either pultrusion or strand pulling production methods. The system is said to be suitable for use with a wide range of base polymer materials and fibre reinforcements, includ- ing glass, carbon and aramid. It can produce LFT pellets with fibre contents of 30-60 wt% in cut lengths from 6-25mm at throughputs of up to 1,000 kg/hr.

“Our objective was to develop a more efficient manufacturing technol- ogy for long-fibre
reinforced polymer pellets,” says Managing
Director Simon Weis. “Our eight-strand pilot system is operating successfully. It is also available for customer trials. We can use it to check on individual custom- er requirements quickly and
product small quantities for test purposes.”
The latest extension to the ips underwater pelletising product line is a compact rotary drum crystallisation unit for PET. The ips-DR/K is available as an optional add-on unit that inte- grates to the pellet dryer and uses the residual energy in the pellets to achieve levels of crystal- lisation of up to 30%. No external heating input is required. The device unit can handle throughputs of up to 2,500 kg/hr. UK-based Accrapak has introduced a new stainless steel water removal tray for its pelletiser product line that is suited for demanding hygiene applications such as pharma. Intended for water removal on lines set up for dry cut strand pelletis- ing, the trays can be custom built and are posi- tioned between the cooling bath and strand pelletiser (either before or after the suction dryer depending on the material being processed). The trays are equipped with grooved PP or stainless steel rollers that strip the water from the strands as they pass through the grooves. The stripped water runs down the slide and back into the cooling bath or into a collection tank, prevent- ing unwanted drips from falling onto the floor. The company says the unit removes most of the water from the strands and, when used in conjunction with a strand dryer, is extremely effective at ensur- ing strands are dry prior to cutting and that the pellets are dry on discharge. Accrapak has already supplied a 4m long by 450mm wide tray for an ASL150 pelletiser processing 21 extruded strands.
