NEW MAXIBATCH™ BLENDER METERS UP TO 2,725 KG/HR. AND PRECISELY DOSES POWDERS, WOOD FLOUR, AND OTHER ‘DIFFICULT’ BULK MATERIALS

Maguire MaxiBatch WSB 2400

For Compounders and Extrusion Processors, including Producers of Wood-Plastics Composites, New Blender Fills Gap between Original MaxiBatch and Standard Blenders

DÜSSELDORF, October 27, 2010: A new model of Maguire’s innovative MaxiBatch™ gravimetric blender provides a new throughput option for plastics processors, enabling them to obtain the advantages of Maguire® Weigh Scale Blenders (WSBs) while precisely and efficiently dosing large quantities of hard-to-handle bulk powders, it was announced by Maguire Products, Inc. at K 2010.

The new MaxiBatch™ 2400 WSB is rated for process throughputs of up to 2,725 kg (6,000 lb.) per hour—50% less than the MaxiBatch 3000 model but 17% greater than the largest standard Maguire blender, the WSB 1800. At the same time the smaller MaxiBatch unit provides the same diverse capabilities that distinguish MaxiBatch blenders from standard WSBs, according to Frank Kavanagh, sales manager.

Besides accommodating higher volumes than standard WSBs, MaxiBatch blenders handle raw materials in a wider variety of forms, including regular pellets and regrind, bulk powders, flake, and ingredients that are especially bridge-prone, such as wood flour. The blenders accommodate up to twelve removable hoppers for as many ingredients, and the hoppers incorporate different dispensing devices, each designed for precise dosing of a particular type of raw material into the weigh chamber. As in standard Maguire WSBs, once all ingredients are metered into the weigh chamber, the batch falls into a mixing chamber. A microprocessor makes corrections from batch to batch, including adjustments to compensate for variations in extrusion rate or bulk density, maintaining overall batch accuracy to within + / - 0.1%.

The specialized dispensing devices in the removable hoppers include: 1) a high-flow corner valve for pellets or regrind; 2) a low-flow pivot valve for pellets, regrind, and some long
glass fiber-reinforced materials; 3) a wood flour / powder feeder with internal bridge breaker; 4) a 50-mm (2-in.) feeder for pelletized additives; and 5) a small-capacity powder feeder. Because the hoppers are interchangeable, it is easy to vary batch recipes, according to Kavanagh.

“The share of operating costs accounted for by raw materials typically increases with production throughputs, as does the likelihood that they will be using bulk powders and other difficult-to-meter ingredients,” noted Kavanagh. “The MaxiBatch system enables companies with the greatest volumes to achieve the same exceedingly fine control over ingredient consumption and batch consistency that standard Maguire blenders have long made available to other processors.”
