The SE air knife guarantees efficient strand drying during pelletizing in both compound and masterbatch applications. Filled and reinforced materials require effective strand drying to minimize the residual moisture of the pellets, reduce dust and avoid premature wear of the cutting tools.
The cooling trough KW assures uniform tempering of strands during strand pelletizing in dry cut strand pelletizing systems. Variable modular length and width as well as many additional options allow adapting the cooling trough KW to almost every requirement.
The classifier is used for separating spears, spelts, chains, oversizes, and multiples from plastic pellets. Classifiers of the SRK-I-C and SRK-I-V type have been designed for the separation of oversized particles both in virgin polymer and compounding applications. The type SRK-II-V classifiers are used for the separation of oversizes and fies in any operation of plastics pelletizing.
Die heads or pelletizing units are used in strand pelletizing systems for extrusion of strand profiles. SG-C series die heads have been specifically developed for applications in masterbatch, compounding and recycling processes. They are used downstream of single and dual screw extruders.
The hot air knife (HAK) is an optional or retrofitting device mounted to the die head of dry cut strand pelletizing systems which efficiently removes melt residues, outgassing remains, and die drools (such as build up of glass fibers) from both the die holes in the die plate as well as from the extruded strands themselves. With the hot air knife, product contamination can be reliably prevented and disruptions to production minimized.
Designed for 24/7 operation and very low noise levels, this vacuum strand dryer has been recognized by many compounders as the preferred method for drying strands. Built on a compact frame the JV series air knife has proven itself as a very effective method of drying strands utilizing vacuum only. Each model has a cantilevered vacuum strip that can be positioned and placed anywhere along the water bath to draw the water off the strands as they exit the water. This takes up less floor space and maximizes the efficiency while utilizing the heat of the strands to expel surface moisture that results in drier polymer entering the pelletizer. A stainless steel cyclone continuously separates the water from the air stream and the water exits to a drain port. The JV head assembly is designed to positively separate and support the strands before and after the suction bar. When placed at the end of the water tank these units can be outfitted with an optional drip tray. This tray collects the dripping water and returns the water back to the water tank. To further increase water savings, a sump pump can be installed to pump the water from the drain to the water bath.
