MAGUIRE WSB 240 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 240 is part of the 200 Series range consisting of 1 hopper fitted with 4 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 Control The WSB Controller has 124 standard features (0.65 BD). and functions that technically make it lead the For enhanced accuracy and consistency on small industry regarding blending control. percentage settings (1% to 4%) a Slide Gate Re- Key to this is the continuous calibration of mate- strictor (SGR-1) is recommended to restrict the opening of the gate by 50%- this reduces flow and enhances control. rials ensuring accurate dispenses of every material within the blend.
