Lead Smelting Furnace
Lead Smelting Rotary Furnace Plant with Pollution Control System
Rotary Furnaces are used in secondary smelting units for re -processing Lead from scrap. Rotary furnaces have an inner brick lining over which scrap is transformed from solid to molten state due to heat given by oil firing. Oil firing is done with the help of a high -pressure air blower.
For Lead smelting & refining: Refined material is discharged into moulds. Rotary furnace is installed on rotary base. It rotates on heavy wheels mounted on base & for pouring finished material; it is lifted by hydraulic cylinders through a power pack.
Our lead smelting rotary furnace is suitable for the recovery of lead out of lead-acid battery scrap, lead concentrate and lead ore. We manufacture & install the oil fired rotary furnace in different capacities with maximum production efficiency and least production cost such as fuel, labor and power consumption. The production capacity of our lead smelting plants can in different parameters may be 3 M Ton to 15 M Ton per day i.e. 24 hours. We provide very effective and efficient pollution control system with the smelting plants, through which a lot of smoke dust of lead is collected. The collected smoke dust from our pollution control system is not only useful to prevent the pollution spreading into in environment but also increase the profit for the extra increase of recovery of lead out of the lead smoke dust collected by the system provided. An estimated value of extra increase of profit is 3% to 4%, which is only capitalized from the further recovery of lead from the smoke dust collected.

Battery Recycling Technology
We are committed to the employment of environment friendly technologies in our solutions for the used Lead-Acid Battery Recycling and Battery Manufacturing Industries, covering Secondary Lead Smelting, Lead Refining, Lead Alloying & Lead Oxides Manufacturing and Lead Pollution Control.
Our Battery Recycling Plant employ Pyro metallurgical processes. Typically, in pyrometallurgical Secondary Lead Smelting, Lead Bearing Battery Materials are charged into a furnace together with appropriate fluxes & reductants, drosses, returning slags and process dusts for smelting. Reduction of Lead bearing material to crude Soft/Antimonial Lead takes place along with the formation of Lead bearing slag. The slag may be collected and smelted in a separate slag campaign in the same or another furnace. Mostly Blast Tilting
are used, either singly or in different combinations, for single/multi stage smelting. The process employed, furnace combination, fluxes, reductants etc. are finalized taking into account the required plant capacity, required product mix, pollution control plant and environmental concerns, the desired level of flexibility in plant operation and the composition of available battery scrap.
Pyrometallurgical processes have been the most widely used for Lead recycling. In a comparison with some other technologically more complex processes, the pyrometallurgical process scores high on para meters like low capital & lifecycle costs and requirement of highly skilled manpower, economic viability of a range of capacities and relatively low core electrical power requirements, among many others. The use of modern pollution control technologies and design ensures environmental compliance. Smaller scale Battery Recycling Plant are a more economically and environmentally viable alternative to large-scale units for many reasons, particularly for developing and small market areas/countries.
Our well-designed tilting Rotary Furnaces, integrated with modern accessories and pollution control equipment form the core of our Battery Recycling Plant, which have proven to be technically and economically viable for a range of capacities, while showing good compliance with environmental standards.
Rotary FurnacesRotary Furnaces have a variety of fitment options, optional tilting mechanisms, a simple, reliable and robust design and display good operating/efficiency characteristics.
Reverberatory Furnaces are those furnaces which is designed and operated in the production of a nearly pure and soft Lead. During charging and tapping Reverberatory Furnace emit high level of Lead Fume.
In Reverberatory Furnace Tapping process the molten Lead and slag is poured from the furnace into Ladles or Molds. Like Blast Furnace, to keep the metal molten, some smelters tap metal directly into a holding kettle. Then comes the task of solidification of molten lead. The smelter casts the molten lead into blocks so that it can be used for the further treatments or operations in various purposes.
Pollution Control Systems
Dust Collection and Gas Purification:
Flue gases from furnaces and air from exhaust ventilation systems are thoroughly cleaned in a state of the art pollution control system. Flue gases pass through settling chamber, cyclone, cooling tower, bag house by induced draft and after that through scrubber to stack with forced draft.
All equipments in the dust collection system have to be properly operated, cleaned, and maintained to control dust particles. The remaining emission is then treated to remove flue gases. Finally the pollution free air, as per international norms, is sent to the atmosphere through a stack.
Equipments Commonly Used
It is used to reduce the inlet loading of particulate matter to downstream collection devices by removing larger, abrasive particles. Settling chambers are also referred to as gravity settling chambers or expansion chambers.
In the expansion chamber, the velocity of the gas stream is reduced significantly, as the gas expands in a large chamber. The sudden reduction in velocity forces larger particles to settle out of the gas stream. To improve settlement efficiency in this settling chamber, baffle plates are provided.
In a Cyclone, the particulate matter is removed by centrifugal and inertial forces. This is induced by forcing particulate laden gas to change direction.
It is provided after the settling chamber to collect the smaller particulate matter that could not be collected in the settling chamber.
Typical gas flow rates in a cyclone varies from 0.5 to 12 cubic meters per second, depending upon the particulate matter to be removed.
To cool down the flue gases down to a temperature that does not burn the filter bags in the Bag House in the pollution control setup. The design is based upon the heat transfer through conduction, convection and radiation.
There is considerable zigzag movement of flue gases in the cooling tower which results in some particulate matter settling down. This matter is removed through valves provided at the discharge end.
Air Filter Bag House:
“Air Filter Bag House” contains 100% polyester Non-woven fabric filter bags fitted in the bag holding cage. The bag house is equipped with pulse jet type cleaning arrangement. Pulsejet cleaning unit is designed for continuous operation that operates at appropriate pressure of compressed dry air.

Pulse Jet-cleaning mechanism and non-woven polyester filter bags are provided for high efficiency of filtration at considerably high temperatures. All the compressed air nozzles are controlled with the help of electronic device to control pulse time and time interval that gives continuous better cleaning by ensuring efficient and best performance of the bag house.
A vertical type chamber in which flue gases enter from the lower end and move upwards. The air velocity is also brought down. The Sulfur Di-Oxide in the flue gases react with the water being sprayed in the chamber and form Sulfurous Acid which flows out into a water tank with some fine particulate particles. The water is circulated with the help of a pump and sprayed through venturi nozzles.
The Scrubber is lined with PVC from inside to reduce corrosion. The acidic water is neutralised in a sequential chambers setup.
