Controlled melting of pulverulent material

摘要

The pulverulent material (glass batch) is fed onto the interior side walls of a melter (rotary drum with interior sloping lining of pulverulent material) from a top chute which includes an adjustable baffle (pivotted cooled plate) for deflecting the feed of pulverulent material towards the interior side walls. The melted material is drained from the bottom. Pref. the angle of deflection is adjusted in response to a detected change in location of the melting surface.
