recognition in the industry. This is the IRD infrared drum that is able to dry and/or crystallise material “in minutes rather than hours.” “Customers in the recycling industry, especially in PET recycling, are seeing the benefits of this solution as it utilises much less energy to crystallise and dry in one machine, compared to conventional technology,” Kreyenborg said. “There is also less in -us e ma ter ia l in th e pr oce ss , wh ic h wi ll re duc e operational costs and issues especially during startup of production.”
Underwater pelletising systems from BKG are supplied with drying, water system and controls and are suited for all thermoplastic materials, also for the production of micro pellets. The company offers systems with outputs ranging from 2-80 kg/hour (Labline 100) to 35,000 kg/hour. For economical processing of PET, BKG has developed the CrystallCut inline crystallisation system that features pelletising and crystallisation in one process step, without the supply of additional energy
As well, the BKG underwater pelletising systems (granulating more than 10,000 tonnes/day of polyester at various customer locations worldwide) are continuing to enter the Asian markets by “replacing a lot of strand pelletising systems due to their product and production advantages.” “ I n p a r t i c u l a r, c u s t o m e r s i n t h e S o u t h e a s t Asian region realise the benefits of underwater p e l l e t i s i n g t e c h n o l o g y, c o m p a r e d t o o t h e r conventional technologies. These customers are in the compounding, masterbatch and polymerisation sectors.” BKG, which says it is the first in the world to offer underwater pelletising systems for engineering polymers, has an economical version that “provides the same flexibility as the standard underwater pelletisers but at a much lower cost.” This system is specifically targeted at customers who are transiting from conventional strand cut technology to underwater pelletising. The group’s success stories in Asia include the delivery of 11 turnkey lines to an Indian compounder in 2009. Nine of the machines are for the production of polyolefin-based compounds and masterbatches, while two machines are designed for the production of polyolefin micro pellets. Last y e a r, K r e y e n b o r g n e g o t i a t e d a major deal with a Chinese company to supply a pelletising system for the production of styrene acrylonitrile (SAN). Kreyenborg Plant Technology is another company within the group that offers a special solution, which is quickly gaining
Catering to the energy-saving trend Necessity is the mother of all innovations and this applies quite well to the plastics sector that requires technology to offer more for less. Along with the changing tides of the world economy, Kreyenborg has been quick to assess these challenges and respond to them. “Quick decision-making, a focus on long-term business strategy and the close relationship between the owners, their companies and employees play a crucial role in our business,” said Kreyenborg, adding that the group employs more than 300 people globally. “ We h a v e r e d e f i n e d i n n o v a t i o n b y s e a m l e s s l y integrating with our machines the capacity for minimised production times, lower costs and energy consumption plus less waste, all for the benefit of end-users.”
The patented MB melt pump was used for a retrofitting project at Bada’s plant in Germany
A recent example of cost and energy-efficiency is a production line for thermoplastic elastomers (TPEs) at Germany- based Bada that was retrofitted with a melt pump and screen changer together with an additional control package designed by Bruckmann. The main objectives of the retrofit were to provide increased performance in terms of higher output an d improved filtration.
"In particular, customers
in the Southeast Asian region realise the benefits of underwater pelletising technology.
