Fast, reliable and flexible: the world of modern bulk weighing


Published on

Bulk weighers are designed for continuous weighing of bulk material. The fast, reliable and flexible systems can provide an accuracy of 0.1 percent or better. Features of the computerised control system can include colour display, menu driven operation, a wide variety of printer options, programmable keys to operate other equipment, power-loss protection, manual backup controls, self-diagnostic and self-trimming.

The increasing need to move materials in larger vol- umes and at faster rates makes reduced horsepower very ben- eficial. The enclosed design con- tains the dust emissions inside of the conveyor, eliminates cleanup of spillage around the conveying equipment and protects workers from moving parts. Conventional belts have been used for many years to move a variety of com- modities, but they were never totally enclosed.
