The newest member of the Guardian Series 2 family of gravimetric batch blender from Atlanta-based Process Control Corp., a 12-kg model, has a see-through mixing chamber door that allows for an unobstructed view of material in the mixing chamber. The all-new design of Guardian Series 2 provides precise batch-to-batch dispensing and consistently homogenous blending. Standard features include off-the-shelf controls, color touchscreen, removable cartridge V-gate metering, segmented material hoppers, integral drain chute, and a “No Dead Zone” mixing chamber.
