Profile: Driver Southall Ltd. is a manufacturer of check weighers, vibratory conveyors, and vibratory weighers for packaging industries. Check weighers have evolved over time from the simple grading check weighers, which simply accepted or rejected packs on the basis of a single set point, to average recording check weighers. They are used to calculate and display statistical information about the production process. Grading check weighers are used to remove inadequate packs on a product line complying with average weights. Our Vibratory conveying action is both gentle and positive, without causing damage to the product with the drive being achieved by either a hydraulic impulse unit or an electro-magnetic unit.
