Ultra-Mix one-step process compounding unit

TRADITIONAL XLPE cables are produced with ready-made compounds from various suppliers. These compounds have predefined recipes of base LDPE, silane or antioxidants and peroxide. Ultra-Mix © has been developed for combining separate compounds on-line during extrusion. offers improvements in several aspects. There is a wide range of suppliers offering base LDPE grades for cable insulation without silane or peroxide and antioxidants. Customers have a large freedom of choice. Traditional XLPE compounds are limited to using chemicals that are solid at room temperatures; otherwise the compound would suffer from chemical sweat out. Shelf life makes storing premix compounds a concern. The use of on-line dosing removes some of these restrictions and gives the cable manufacturer a wider selection of silane or peroxides and antioxidants. On-line dosing offers a significantly longer shelf life. Using alternative peroxides can even result in increased extruder outputs and longer production runs. The E-Xhead system for silane or peroxide and antioxidant dosing consists of one to seven feeders with gravimetric measurement for accurate dosing. When different solid compounds are ready as a batch, precision injection of silane or peroxide and antioxidant is effected. While liquid and solid are mixed together, the next batch is under preparation. Key features of Ultra-Mix: • It can be simply installed on any extruder within one day • System is independent of the extrusion line PLC, therefore no requirement to connect unit to the extruder line control system On-line compounding
