A Batch Weighing System is similar in design to a continuous Loss-In-Weight Feeder. Batch applications do not, however, require that material be continuously fed with high-feed accuracy. They do require that the desired weight of material at the end of the feed cycle is accurate. Control of batch size and feed time is provided through a unique control package that eliminates the effects of plant noise. Batch accuracy of 1/4 to 1/2% or better can be achieved.

Controlled discharge from storage and non-pulsating feeding of materials are critical for a successful batching system. Vibra Screw’s wide range of controlled vibration feeders and material flow aid devices permits superior accuracy in both loss in weight and gain in weight batching over a wide range of capacities.

The Vibra Screw approach to batch weighing combines the latest in electronics technology with more than 50 years of experience in handling bulk materials. The result is a carefully engineered total solution for your particular needs, backed by a performance guarantee to insure your complete satisfaction.

Proper batch weighing demands a full understanding of the physical properties of materials and their characteristics in motion. Too often, suppliers are skilled only in the electronics aspect of the system and neglect the material handling consideration or leave it to others. Vibra Screw is unique in the industry, combining its own mechanical and electrical designs.

The Vibra Screw Test Center is fully equipped with all of our many batch weighing products to demonstrate the best individual unit or complete processing system to handle your unique material.
