In simple cases there is “only” excessive wear at the grinding tools; massive foreign bodies, however, can cause a breakdown of the machine. There are different approaches of how to solve this problem and how to avoid a breakdown. All of them, how- ever, have detrimental effects: inductive metal separators are only appropriate for detecting metals – but often foreign bodies are not metal parts but stones, shoes, wooden pieces. Alternative solutions are often too expensive or need too much room. For the separation of foreign bodies Herbold Meckesheim GmbH has developed a simple, efficient solution that is part of a pneumatic conveyor. Heavy materials are separated and evacuated from the product flow in an ascending pipe via a discharge chute. The advantage is twofold: firstly, the foreign bodies are separated and, secondly, any further transport is no longer necessary. The underlying principle is that materials with a considerably higher flying speed in the conveying pipe of the pneumatic system are separated out. A first plant has been sold for a PET bottle recycling line: entire bottles, not yet size-reduced, are separated from foreign bodies and at the same time con- veyed to the next processing step. The line is suitable for processing bottles that have not yet been size- reduced, but it is also appropriate for separating foreign bodies from pre- shredded thick-walled parts. Not only metal parts but also mineral foreign bodies – generally all heavy parts are separated. www.herbold.com CCT – SYS GmbH Idsteiner Strasse 74 D-65527 Niedernhausen, Germany a.schmitz@cct-systems.com www.cct-systems.com Portfolio Caps • Closure molds beverage field (produced under the brand “CCT Systems®)” - Completely new constructed and optimized molds for closures with slitted tamper evident band (SBT) - Completely new constructed and optimized molds for closures with slitted and folded tamper evident band (SFBT) • Devices and equipment for closure production Portfolio Preforms • Preform molds and preform molds cold halves • Conversion parts and spare parts for preform molds (here especially conversion parts for the weight reduction according to “ComPetCap®” construction) • Devices and equipment for preform production Consulting and supporting possibilities for • Closure development • Closure production • Closure processing • Preform development • Preform production PET Molds and Accessories Developments PET - Devices and Equipment Closure – Devices and Equipment New Range of Services Consulting und Support Closure molds and Accessories
