Loss-in-Weight Feeders

These loss-in-weight feeders 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. A controlled vibration feeder design for weigh feeding means minimal loss of accuracy during the volumetric refill cycle and high accuracy in the gravimetric mode. The versatile line of weigh feeding devices includes pan or tube feeders, screw feeders, and belt feeders.
