Utilizing Schenck Process VKD software in its DISOCONT Tersus feeder controller, Schenck Process has adopted a method that reduces batch feeding errors by up to 50%. The process is known as bumping and it follows the philosophy of running a dry material feeder at full speed, stopping it prior to the batch set point and then having the controller bump the helix motor in a range anywhere from 100 millisecond to 100 second intervals until the batch is within the specified tolerance. Following this method of batching requires you to disable the automatic adaption on the controller, which prevents it from changing the correction amount. By doing so the controller can be stopped short of the batch set point and then bumped to the tolerance specified in the parameter. Lab testing has proven this method to reduce batch feeding errors by up to 50% dependent on the material and helix type.
