Continuous Gravimetric Blenders

Our continuous gravimetric blenders are designed to provide an accurate and homogeneous blend of materials for extruder-mounted, mezzanine-mounted and central blending applications. Our high resolution weighing system allows precise low-rate additive feeding to minimize usage of costly materials.

Because gravimetric blenders control material feed by weight, they are able to rapidly compensate for variations in material bulk density. The operator enters the desired blend percentages into the operator station. Each material is contained in a separate weigh hopper with integral auger feeder. The blender's computer continuously monitors the actual feed rate of each ingredient and periodically adjusts each feeder speed to maintain the preset blend percentages by weight. All materials then flow through a cascade mixing chamber which thoroughly homogenizes the blend. For extruder-mounted applications, the homogeneous blend is then captured in a plug flow hopper which preserves the blend homogeneity to the extruder or other processing machine.
