MAGUIRE WSB 440R 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 440R is part of the 400 Series range consisting of 1 hopper fitted with 2 material compartments and 2 removable hoppers. Operation Each main 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 removable hoppers have a built in 1” Pivot Valve to dispense small components such as additives and masterbatches, typically from 0.5% to 5.0%. Control The WSB Controller has 124 standard features and functions that technically make it lead the industry regarding blending control. Key to this is the continuous calibration of materials ensuring accurate dispenses of every material within the blend. The hoppers are mounted above the Weigh Bin with The Controller every dispense updates the gram/second flow rate of each material, ensura default 4000g batch size.
