MAGUIRE WSB 960 Gravimetric Blender Product Technical Data Sheet Design The Maguire Weigh Scale Blender™ (WSB) range of gravimetric batch blenders are for all plastics converting businesses for all types of extrusion applications, and also all Injection and Blow Moulding applications. The WSB 960 is part of the 900 Series range consisting of 1 hopper fitted with 6 material compartments. Operation Each material is dosed by a stainless steel slide gate. The slide Gate is capable of dosing a wide ranger of settings, from as little as 1% to 100%, based on an average density free flowing material (0.65 BD).

The complete batch is released into the mixing chamber, and mixed with the previous batch to ensure a homogenous mix. For special functions these can be easily accessed and set via the password protected keypad. There is audible alarm and strobe light with silence function, should a batch be incomplete, for Material blending is controlled by a level sensor example running out of additives or master- mounted in the upper part of the mix chamber. batches. When the sensor is covered the blender will not dispense any further batches. The level of material in the mix chamber is critical to good mixing. Setup and Operation reports can be printed direct to a USB key. Data is also available via Ethernet or serial As material in the mix chamber is consumed the ports, allowing remote access and monitoring to sensor is uncovered and then the blender then download settings and check job progress. commences the next cycle. Integration to other control or ERP systems can be made via leading fieldbuses or OPC interfaces
