Underwater Pelletizing
Systems
Function
How It Works and operation
In this process, raw polymer materials are introduced into the feed hopper, which then conveys them into the screw barrel. The screw barrel houses one or two screws, depending on the desired throughput and the specific polymer being processed. Each screw comprises distinct functional zones, including the conveying zone, melting zone, and metering zone. Molten polymer is then extruded through the die head, forming strands that are subsequently cut into pellets by the rotating knife assembly. The rapid solidification of the pellets is facilitated by the surrounding water in the cutting chamber. These pellets are then transferred to a centrifugal dryer where residual water and moisture are removed, preparing them for packaging and distribution.
Specifications
Materials and Construction
TGT Company designs and optimizes underwater pelletizing systems tailored to the specifications of the produced granules, the production capacity, and the variable environmental conditions of the product.
The Die Head Assembly
The die head assembly forms uniform polymer filaments by consistently directing the molten polymer flow through a specific number of holes. The standout feature of the die head manufactured by TGT Co. Company is its ability to create defect-free, uniform threads.
The Knife Cutter
The knife cutter is a specialized blade used in multiple sets to cut the polymer and produce pellets. Depending on the type of polymer and operational conditions, Taha Ghaleb Toos Company designs and manufactures knife cutters with varying dimensions, geometric shapes, and high hardness, ensuring wear resistance and optimal performance.
