Vibra Screw offers loss-in-weight (LIW) feeders that provide accuracies to ± 1/4% to 1/2%, weighing ounces to tons and feeding materials from fine powders to fibrous or flaky materials. Control of batch size and feed time is provided through a microprocessor-based controller that eliminates the effects of plant vibration and electrical noise, and the need for vibration-dampening devices. The controllers incorporate user-friendly, menu-driven software with membrane keypads and easy-to-read displays. Vibra Screw offer a controlled vibration feeder design for weigh feeding, which results in minimal loss of accuracy during the volumetric refill cycle and high accuracy in the gravimetric mode. The versatile line of weigh feeding devices include pan or tube feeders, screw feeders, and belt feeders.
