Loss in Weight Feeder

True to its "loss in weight" name, this feeder's operation is regulated by the amount of live load that is lost as product is discharged. In order to do this effectively, the loss in weight feeder receives constant feedback from a sensitive weighing device, which ensures that the precise amount of material is delivered either continuously or in each batch.Get price
