CHINAPLAS: Material treatment solutions from ProTec

ProTec Polymer Processing will be presenting efficient plant engineering solutions for material treatment and solution concepts for flexible and economic material handling. Highlights at the company's stand will include the new, optimised solid-state reactor (OHL tumble reactor) for selectively improving the properties of free-flowing materials, LFT technology for producing long-fiber reinforced thermoplastics and systems for drying, conveying and dosing granulates and mill base. The SOMOS? TF 40 eco auxiliary dryer on show at the trade fair displays the impressive flexibility and energy efficiency of the SOMOS? dry air dryers.

The OHL tumble reactor is a solid-state polycondensation (SSP) reactor that can be heated and evacuated. It is available in coordinated modular sizes, from 50-litre sizes for laboratory use all the way to large 44 m3 containers for manufacturing plants. Designed for improving the properties of free-flowing materials, the reactor on display at Chinaplas will feature optimised geometry as well as revised drive and control technology.  

The plant technology for manufacturing long-fibre reinforced thermoplastics (LFT) presented by ProTec Polymer Processing is suitable for manufacturing a broad range of materials using a diverse polymer matrix and different types of fibre reinforcement. These composite materials are created with fibres of granulate length – lengths of 7 mm to 25 mm are the industry norm – using what is called the pultrusion process.

With a mobile dyer from the SOMOS? T/TF eco range, ProTec Polymer Processing demonstrates its plant technology and expertise in the area of economical, energy-efficient, and flexible material handling. These mobile dryers consist of a drying air generator and an insulated stainless steel drying hopper. They are available as a TF version with an integrated conveyor mechanism for automatically feeding the processing machine, or as a T version without this feature. The hopper geometry is optimised to the material flow, resulting in a uniformly low variation in retention time for the material to be dried, which in turn ensures consistent characteristics in the dried material.
