Text Box: The molten metal is discharged through a perforated metal section attached to the lower end of the rotary retort. This molten metal is collected in a transverse positioned launder (E), which feeds the molten metal into the customer’s receiving molds. Any drosses and ashes that are formed in the process will also be discharged through the perforated metal section, but angularly displaced from the molten metal discharge. The drosses and ashes are collected in a draft box which is attached to the furnace at this location. Any non-melted materials such as iron or brass will be discharged at point (F) and can be collected in customer’s containers or conveyor. Combustible contaminants associated with the raw scrap materials will burn during the process. The smoky gases generated will be collected in the smoke hood (C) and exits to the pollution control system at point (B) on the smoke hood.
