Lead Smelting Rotary Furnace Plant

Lead Smelting Rotary Furnace is a mechanized furnace, Round Shell with both ends conical. Conical ends are open on both the sides. Rotary Furnace works in a batch process. Raw material is charged from one end along with certain chemical and additives like coke breeze, cast iron chips, soda ash etc.

Rotary Furnace is heated with the help of Burner which uses oil or gas as a fuel. The Furnace is heated continuously and also keep rotating at very low speed of up to 1 to 1.5 RPM. Rotary Furnace rotates with the help of tyres around the furnace shell mounted on four roller wheels. These Roller wheels are fixed on a MS structure frame duly fitted in Bearing & Bearing Blocks. Wheels are driven first with the help of Electric motor coupled with Speed Reduction Gear Box & driving shafts, which rotates the furnace shell also.

Furnace Shell is lined with CFK or HFK Insulation Bricks and High Alumina 70% refractory fire bricks. Both conical ends of the furnace are open. The front end of the furnace is used for the charging of raw material as well as heating with the movable burner. Burner is shifted aside at the time of charging raw material along with additives & then again moved at the mouth of the furnace for heating & melting of the scrap.

Furnace is rotated for the proper mixing and reaction of the additives and as the Lead metal in molten state occurs, it is discharged into the moulds from the Taping Hole provided at centre of the furnace. After draining the Furnace of the first batch, production of next batch is undertaken and the Furnace is again charged with raw material. After three such batches, one batch of slag collected in Rotary Furnace is executed. Processing in the furnace is done at high temperatures and therefore it is operated continuously for long periods of time. It is used for production of large quantities and need skilful handling & maintenance.
