Kopp replaced a rotary pan mixer with a Munson rotary batch mixer a horizontal, rotating drum with a stationary inlet at one end and a stationary outlet at the other. Mixing flights, or baffles, tumble the batch in a multi-directional manner.
The flange of a discharge valve at the hopper's outlet, is positioned atop the inlet of the mixer using an overhead hoist and trolley, due to ceiling height restrictions.
The batch is rapidly discharged from the mixer into a cart that transports it to the furnace.
Access doors facilitate interior inspection, cleaning and maintenance.
The gatherer uses a punty, which is continually turned, to accumulate molten glass from the pot, and transfer it to a mold.
