Be prepared: advances in materials handling
Recent developments in materials handling include feeder and blender upgrades, updated software for dosing systems and carbon tracking for material logistics
Preparing granulate and other raw materials for the extrusion process can involve a range of processes, from drying and dosing to weighing and blending. Many suppliers introduced their latest products in these areas at K2022 last year. Maguire, for instance, introduced its new WSB-600 series blender at the show. The new series of gravimetric blenders, for
mid-range throughput applications, precisely dispenses up to 12 materials – including regrind, flake, wood flour and talc filler – and can be configured to dose up to six major ingredients. The 600 series has a throughput range up to 2,500 lbs/hr. The WSB-600 adds another model to Maguire’s line of weigh scale blenders, which already includes over 150 configurations. Each ingredient hopper has a dispensing device designed for a material in a specific form. Like the larger units in the WSB family, the new blenders can be outfitted with up to six large-component slide gates for dispensing major ingredients, along with any combination of large corner valves (11,000 g/sec), 4in vertical valves (2,000 g/sec), 2in vertical valves (400 g/sec), auger feeders, and liquid colour pumps. “By providing the same flexibility as larger units,
the WSB-600 series blenders enable processors working in a smaller throughput range to meet growing demand for products that incorporate regrind and PCR along with virgin resin,” said Frank Kavanagh, vice president of marketing and sales at Maguire.
In addition, Maguire introduced a new line of
feeders, providing complete application flexibility with added choices of gravimetric feeder. Its MGF+ models allow processers more flexibility and increased performance. They can be retrofitted with current Maguire equipment.

Carbon tracking At K2022, Altair and Motan demonstrated a carbon footprint tracker technology. Evaluating carbon footprint is essentially an information problem. Plastics converters need

The MGF+ line includes up to four different- sized auger feeders on one mounting frame. This allows the flexibility to dispense multiple additives and materials within one frame and one controller. The centre hopper dispenses virgin material. MGF+ 100L includes a virgin hopper that is on a
pair of load cells, so that the material within this hopper is also being weighed and controlled by the same controller. It is ideally used for extrusion applications. MGF+ 100X takes the process control one step further by including an extrusion control package, where the extruder drive control is managed with the same touch screen controller as the hopper and the feeders.
