Batch charger control options and effects

The controls of batch chargers can have a direct effect on the efficiency of the melting process as well as the environmental conditions associated with the process. The authors outline control options and describe the effects. Emphasis is placed on the blanket-type batch/cullet feeder, one of the mainstays of the large volume glass producer. The control options which are incorporated include positive materials displacement, i.e. metered discharge; charger pan speed variation; charger pan stroke variation; and charger pan angle variation.<
