RAPID launches Low Built Base Granulators for sheet and film
Granulator equipment specialist Rapid has launched the LBB 300 series, a granulator with a very low height for handling sheet and film scrap. The new unit (LBB stands for Low Built Base) is intended principally for use in-line with a thermoforming unit, where its very low height allows it to be located directly under the output conveyor, saving valuable floor space. The LBB 300 series, which appeared in prototype form at K 2013 in Düsseldorf two years ago, made its official commercial debut at the Fakuma show in Friedrichshafen, Germany, on October 13-17.  It is available worldwide. Height of the LBB 300 series is just 600 mm (excluding feeder) and it is available in three widths: 900, 1200 and 1500 mm. The unit can be equipped with a rollfeed unit synchronized to the thermoforming line speed, or with a simple tray that collec ts skeletal frames as they fall from the line. The modular granulator can also be configured to fit directly under a shredder to provide final size reduction, without the need for the conveyor belt used in common practice for connecting the two units.   The LBB series is available in several model versions with a choice of rotor and hopper types, depending on the application. The very compact design of the LBB 300 series means that it takes up very little extra space on the production floor. Depending on model, width is between 2000 and 2300 mm, and depth is 700 mm. It is designed to handle film and sheet up to 8 mm thickness, depending on material. The LBB 300 series uses a true scissors cutting action to provide clean and precise cutting of sheet and film, and high quality regrind. The rotor on all models is 300 mm in diameter, fitted with six, eight or ten blades depending on model size. The two smaller units have six fixed knives, while the largest has nine. Units can be fitted with motors rated at between 7.5 and 30 kW. Maximum throughput capacities range from 800 to 1200 kg/h. Output can be transported via a vacuum conveyor straight back to the production line for reprocessing. All units are fitted with a rotor stand-still guard for operator safety. The two larger units both feature split screens and split screen boxes for extra ease of service and maintenance. The equipment is mounted on a solid stand with castors for ease of movement when required. Basic units weigh between 1200 and 1500 kg, depending on size

CONAIR lab to drive extrusion innovation
Conair’s Extrusion Division has built what it claims is one of the most advanced plastics extrusion laboratories in the world, to help customers to push the boundaries of productivity and profitability.   The opening of an extrusion equipment manufacturing facility in the US has allowed the company to create a 742M² state of the art laboratory dedicated to extrusion development and testing.  The Conair extrusion development and testing lab houses four production-scale extruders manufactured by various well known industry brands and it is staffed by three experienced full time process engineers.   In addition to conducting factory authorised testing to confirm that a new extrusion line (comprising an extruder, application-specific tooling, gauging and downstream equipment) can meet performance guarantees, the lab also conducts trials for extrusion companies.  Customers can enlist the help of Conair’s extrusion experts in perfecting the line set up of new products or experiment with new equipment of processing techniques to maximise productivity and profitability of existing product.   In addition, Conair used the lab to develop and improve the downstream systems it manufactures.  Recent work has been aimed at perfecting online gauging and adaptive control for extrusion of precision medical tubing, including cardiac and brain catheters. However. the products being tested could just as easily be larger equipment for extrusion of siding, pipe or profiles.   Conair says while most extruder manufacturers have lab facilities, they are preoccupied with perfecting the operation of the extruder.  Conair says its lab is more adapted to evaluating and maximising the performance and productivity of the entire line, including downstream equipment and even auxiliary systems like dryers, loaders, blenders and heat-transfer equipment.
