Our powder metering systems include a hopper that is supplied manually or by Autolift (optional), and a variable-drive feed screw beneath the hopper that ensures a precise rate of flow. TMI can also provide metering solutions for fine powders that tend to stick to the hopper walls or absorb humidity. To overcome this issue, we can supply centre-mounted hopper arch breakers that guide the powders to the metering screw, as well as vibration units.
