Industrial Grade Rotary Melting Furnace can be used for recycling much non-ferrous metal and is flexible type in nature. The Furnace has the feature of equipment scalable for installing higher capacities and recovers all lead in one production cycle. The Furnace can be fired with various fuels and generates high pollution both as flue gases and fugitive emissions. The Industrial Grade Rotary Melting Furnace has the feature that apart from plates and paste of lead oxide from scrap batteries, slag from mini blast furnace is charged in the rotary furnace.
