Gravimax blender can mix and meter up to 8 ingredients

Gravimax Wittmann Battenfeld’s Gravimax blenders come in numerous sizes and configurations with throughputs ranging from 170 pounds to 3,900 pounds per hour. The gravimetric blenders can meter and mix as many as eight ingredients and feature precise metering valves, interchangeable steel hoppers and an easy-to-use controller.

What’s new? Two metering modes: reference additive and reference virgin. Strong vibrations or impacts can cause incorrect additive dosing; therefore, in reference additive mode, the blender instantly adjusts the quantity of virgin resin to maintain the proper ratio with the additive that already has been dosed. Reference virgin mode addresses the challenges of dosing additives into plastics reinforced with long glass fiber (LGF). In that mode, the quantities of the other components are adjusted based on the amount of virgin LGF resin ready to be blended.

Benefits Accurate metering and quality end products. The new metering modes prevent color fluctuations and wasted materials.
