Whereas most batch gravimetric blenders weigh each ingredient one at a time into a blender bowl, Plast Control’s first gravimetric blender has two weigh chambers with load cells. Each receives material from two or three ingredient hoppers. Each ingredient hopper has two slide gates, a large one to drop most of the load, then a small one to finish the weight more accurately. The photo shows a top view into a hopper, with the wide-open outlet on left (white) for high-rate dosing and the dark restrictor plate that slides over the outlet for low-rate dosing. (The outlet on the right is for flushing out the chamber.) Dosing units can be added for low-rate additive feeding. Plast-Control’s Pro-Batch empties both weigh chambers into the mixer.
