The Magna Weigh Feeder® is a simple in-line weighing conveyor designed to feed products by weight. It combines the simplicity and cleanliness of a vibratory conveyor with the weighing capabilities of a weigh belt. The Magna Weigh Feeder® is superior to volumetric feeders in its ability to compensate automatically for changes in the bulk densities of products. A signal, proportional to product rate, may be used to control one or more slave products in seasoning, mixing and blending applications.
