Methods of Batch Feeding and Weighing Bulk Material Handling Products

There are two main methods of batch feeding and weighing bulk material handling products: Loss-in-Weight Feeding, and Gain-in-Weight Feeding.


Dry bulk solids (such as powders, granules, pellets, flakes, and fibers) can behave in different ways. This typically varies with each material’s chemical and physical characteristics and flow properties. Some major characteristics are the size and shape of the particles, the material’s bulk density, compressibility, cohesive strength, moisture, oil or fat content, and the way in which the material behaves under atmospheric and loading conditions.


Many different bulk solids materials have different flow behaviors. This can greatly vary depending on the material properties or particle geometry. The Geomate
Feeder’s vibratory technology can handle most bulk solids feeding challenges.


The following is a list of materials that the Geomate
Vibratory Feeder can handle:


•Easy-flowing materials, such as plastic pellets, granules and flakes. Vibratory feeders can provide highly accurate and reliable feeding of these types of free-flowing materials.
•Difficult-flowing materials, such as fiberglass and rubber particles, can also be accurately fed with the Geomate
Vibratory Feeder.
•Floodable materials, such as diatomaceous earth and certain flame retardant materials, can behave like liquids if not properly controlled during hopper discharge and feeding. The Geomate
Vibratory feeder can be used for some of these materials, but often times depending on the floodability of the product, a screw feeder is often the best choice. Material is controlled through the intermeshing screw flights which act like valves.
•Cohesive materials, such as titanium dioxide, can be tough to handle during the operation process. These materials often encounter bridging inside hoppers, and sometimes stick to equipment surfaces. The Geomate
Vibratory Feeder can handle such materials with accuracy, and due to its design, greatly reduces the possibility of bridging and sticking to equipment.
•Fragile materials, such as many types of fibers, can be handled using the Geomate
Vibratory feeder. Other types of feeders that can handle this type of materials include Weigh Belt Feeders, and Loss-in-Weight belt feeders.
