MAGUIRE WSB 1840 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 1840 is part of the 1800 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 (0.65 BD). For enhanced accuracy and consistency on small percentage settings (1% to 4%) a Slide Gate Restrictor (SGR-1) is recommended to restrict the opening of the gate by 50%- this reduces flow and enhances control. The hoppers are mounted above the Weigh Bin with a default 18kg batch size. In normal operation the system tares the weight of the weigh bin and then each material is dispensed Regrind, Natural, Colour and Additive in sequence, 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 Controller every dispense updates the gram/second flow rate of each material, ensuring consistent accuracy. Settings are made easily by either user friendly thumbwheels, or entering settings directly on the keypad. weighing each material after each dispense confirm- For special functions these can be easily acing material required before moving on to the next cessed and set via the password protected keymaterial. pad.
