NPE 2015
National Bulk Equipment will be showing its latest flexible screw conveyors and hoppers built for harsh applications and demanding environments. The gear drives and motors are specified for maximum power and conveying efficiency, while the conveyor discharge head is made from high-quality stainless steel. It is assembled and hand-finished to eliminate any gaps, joints or bolts that could accumulate material. Stainless steel is also used for the hoppers which

feature steep-slope sidewalls, sheer-drop material feed guides and flangeless conveyor intakes. These help to eliminate bridging and rat-holing, while also improving access for cleaning. ❙

Nordson BKG will be introducing a new belt filter for the temperature-controlled water system of its Master-Line underwa-
ter pelletizers. The optional unit has been developed to reduce downtime and operator

Kreyenborg’s new filter
cartridge is
already proving its worth on a PET recycling line
intervention by providing continuous, automated filtration of fines. The new filtration system also has a finer filter mesh – 150 µm versus the 200 µm capability of the standard system available with Master-Line pelletizers. It is a modular system that can be used to upgrade existing Master-Line equipment. The continuously rotating filter screen is constantly
cleaned by spray nozzles at one end and a scraper at the other, allowing fines to be collected in a catch basin beneath the belt. In the standard system, fines are
collected on a large woven wire-mesh screen that periodically must be removed and cleaned, a process that requires stopping production. BKG’s Master-Line pelletizer is a compact, entry-
level system for compounding and recycling at through- puts up to 2,000 kg/hour. Nordson BKG says that the new belt filtration option provides the machine with the finer filtration and self-cleaning features found on its higher-cost Combi-Line and Opti-Line pelletizers. ❙

Nordson Kreyenborg will be highlighting a new screen-changer filter cartridge that is designed to resist deformation and enhance polymer flow. It is already being successfully used by a European company on a high-throughput PET recycling line supplied by Starlinger, where it is reducing the frequency of filter replacement and improving pellet quality. The bottle-to-bottle line features a Starlinger
RecoStar PET 165 HC iV+ recycling machine and a Nordson Kreyenborg K-SWE-4K-75/RS screen-changer between the extruder and the underwater pelletizer. When the company replaced a standard filter medium in the screen-changer with the new filter cartridge, the filter life was extended from eight to 72 hours. Besides prolonging
filter life, the innovative design of the new filter cartridge also handles the requirements of high-throughput systems such as the 1,400-1,600 kg/hour (3,000 to 3,500 lb/hour) Starlinger line. Its larger filter area and the elimination of stagnation zones help to reduce pressure variations that can detract from pellet quality. ❙

Pelletron will be showing its XP-360 DeDuster with a new automated inlet device which eliminates the need for expensive and heavy rotary valves that are typically used to feed materials into the units. The automated inlet deflectors adjust the product flow to the desired rate. They also evenly distribute product over the wash decks of the DeDuster and can shut down product flow completely. This DeDuster model is designed for cleaning
