Product Description
Water Cooling Strand Pelletizer
Strand pelletizing (cold cut)
Melt coming from a die head is converted into strands that are cut into pellets after cooling and solidification.
It is suitable for master batch, compounding and engineering plastics.
A line utilizing a simple water bath for strand cooling often is the first option for compounding plants. However, the individual layout can vary significantly, due to the demands of throughput, flexibility, and degree of system integration. In strand pelletizing, polymer strands exit the die head and are transported through a water bath and cooled. After the strands leave the water bath, the residual water is wiped from the surface by means of a suction air knife. The dried and solidified strands are transported to the pelletizer, being pulled into the cutting chamber by the feed section at a constant line speed. In the pelletizer, strands are cut between a rotor and a bed knife into roughly cylindrical pellets. These can be subjected to post-treatment like classifying, additional cooling, and drying, plus conveying.
Cowin’s water baths are designed to meet the needs of your extrusion line. Made of 304 stainless steel, our cooling tanks are available in multiple sizes to accommodate most extrusion applications. Our rugged painted steel support frames are equipped with heavy-duty support jacks for adjusting the height. A weir box with removable screen is standard along with inlet and drain ports.
