Underwater pelletizer is aimed at lower throughput applications Gala G m b H has introduced a new low cost underwater die face pelletizing system aimed at compounders with a requirement for shorter production runs and lower throughputs in the range 50-500 kg/hour. The MB 500 system is said to be easy to clean and has a fast turnaround. The company adds that the machine should also be of interest to the masterbatch producer. The pelletizer has a dryer that is quick and easy to clean through a lift-and-swing away construction with a support arm. The housing can be removed by unfastening three
bolts. The screen is of a twist and pull away arrangement, which means that the rotor is then fully exposed for cleaning. The water tank is also easily accessible through two hinged tank lids to allow easy cleaning. The apparatus includes an easy to clean fines removal sieve that removes all the fines out of the process water. The system is fully automated with a $7 PLC operator panel. Gala says that a choice of cutting systems is offered, including the new PAC pneumatic pelletizer, which can be supplied in either semi-automatic or fully automatic forms.
The company says that other benefits of its underwater pelletizing systems include a flexibility to cut low viscosity and tough materials, such as TPEs, that cannot be strand cut, as well as highly viscous filled materials. Gala adds that a high quality, uniform freeflowing pellet is produced and the operation is automatic and can be unsupervised. The machine is compact and is fully enclosed, which prevents contamination. Contact: Gala GmbH Tek +49 2801 9800 Fax: +49 2801 98010

US company Farrel Corporation has introduced a computer-aided remote diagnostics system (CARD®). By using a modem connection with the operating equipment, Farrel says that the CARD system allows complete control of operating parameters for optimum productivity. It can also keep archival records of past operations, monitor alarm functions and take continual system and process readings. The system is applicable to all Farrel lines of polymer processing equipment. CARD system data can be relayed to Farrel personnel in the company's process laboratory for advice on work with experimental batches and processes. Farrel says that control and monitoring data are transmitted to replicate workstations where the performance of the equipment can be assessed in real time. This can allow data evaluation, enhanced equipment and process functions and permit rapid troubleshooting. Farrel says that the benefits of the system include reduced maintenance costs and minimal downtime. Contact: Farrel Corporation Tel: +1 914 761 5998 Fax: +1 914 6865298
