Improved Design of Two-Screw Batch Charger for Glass Furnaces

Resumo

An improved design of a two-screw batch charger for glass furnaces is presented. It is noted that a change in the shape of the pushing shutter equipped with two trapezoidal side sections makes it possible to optimize by means of an additional pivot turn of the pusher arm around its axis the distribution of the batch over the molten-glass surface in a sealed doghouse.
