New heat-resistant elastomer feed roller for pelletising systems

The EL 24 also offers better frictional resistance and compression behaviour than conventional elastomer feed rollers, says the company. The new roller is white and also silicon-free. Feed rollers are exposed to a wide range of loading based on the different materials processed in compounding and masterbatches. The products they process are soft, brittle, abrasive and/or very hot. The feed roller therefore has to be closely adapted to the material being processed. Demands on elastomer rollers are very high particularly in relation to abrasive materials incorporating reinforcers such as fibre-glass or high-temperature additives. Optimum service life is important, so as to maximise system availability and minimise production cost. The new EL 24 feed roller is designed specially to handle such high loads, says the company. Long-time tests by a variety of customers subject to high loading on feed rollers have demonstrated that using the EL 24 results in four to five times longer life.
