Stirrer and how it function? :

• Propeller type Stirrer transform Electrical torque into centrifugal force to dispersion and emulsification force depends upon R.P.M.
• Resonance is created in case of refining dispersion of metal is produced which separates metal according to its density, so vessel height, diameter of impeller and no. of impeller is important factor.
• But for alloying of metal with other metal, emulsification is created by changing R.P.M. and diameter of Vessel.

Fluid-O-Matic Alloying Pot :

• No. of Stirrer are increased to two and aerofoil design is incorporated.
• No. of Blade are three.
• Distance of stirrer from bottom is more compare to refining pot.
• Thicker Shaft is used and balanced dynamically so in case of lesser fluidity due lesser temperature it resists unwanted forces.
• Surface Area is increased by mounting extra fins all around the pot. So transmission of heat is vertically transfers through fins to the pot and extra fins give more contact area with flame and flue gases at one end another is welded with the vessel so transmission is faster in conduction than radiation medium.
• This effects in transmitting heat to the molten lead because with the increase in temperature conductivity of heat is reduced in lead.
• Heat transmission is increased so pot itself does resists its oxidation/ burning/combustion. Due to lesser temperature difference from inner surface to outer surface.
• Difference of Temperature form bottom to top layer of metal is reduced.
• More thickness is used which also assists in heat storage and transmission  of heat.
• Above all it gives longevity, increases performance, increases durability  of the pot.
• Emulsification of metals is required in alloying. It is very much important , so stirring  is done accordingly.
• So. By summarizing above facts, Fluid-O-Matic Alloying Pot gives better Alloying of Lead with other metals.
• Better return, Lesser consumption of fuel which are coupled with Better design of Burner made us.

Details :
Flow air/ flue gases out of Furnace to Stack. So some force is required to move flue gases through the Settling Chamber, Cyclones, Cooling Lines and bag house. This force is induced by the Blower on flue gases. Blowers/ Fans exert a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other system components in a gas flow system. The fan/blower rotor/impeller receives torque from a rotating shaft of electric motor or some other driver. Impeller of fan/blower forces gases through the system.

As RPM is increased for more flow, power is increased cubically whereas if diameter is increased then power is only doubled, so bigger size of blower is more useful at lesser RPM than smaller size blower at more RPM.

Basic requirements for Blower are following :

• Air Volume, this depends upon fuel consumption in the system and required pressure in the furnace
• Drive type, Direct driven / indirect driven / Direct coupled
• Operating Temperature
• Blower RPM will make less/ more Motor H.P.
• Construction material, depends upon flue gas

The Lead Bullion is fed into a refining kettle. Lead bullion contains many other metallic impurities including antimony, arsenic, copper, tin and zinc.

Refining Process of Lead in Detail :

• Removal of Copper : Copper is the first of the impurities to be removed. The lead bullion is melted at about 300–600 °C and held just above its melting-point when solid copper rises to the surface and is skimmed off. Sulfur is stirred into the melt to facilitate the operation by producing a dry powdery dross which is more readily removed. Once copper has been removed, there are a number of processes available for the extraction of the other impurities from the bullion. These include, in which elements are removed one or more at a time in several stages.
• Removal of antimony, arsenic and tin : After the removal of copper, the next step is to remove antimony, arsenic and tin. There are two methods available — the softening process (so-called since these elementsare standard hardeners for lead) and the Harris process. In the softening process, the lead bullion is melted and agitated with an air blast, causing preferential oxidation of the impurities which are then skimmed off as a molten slag. In the Harris process, the molten bullion is stirred with a flux of molten sodium hydroxide and sodium nitrate or anothersuitable oxidizing agent. The oxidized impurities are suspended in the alkali flux in theform of sodium antimonate, arsenate and stannate, and any zinc is removed in the form of zinc oxide.

• Removal of silver, gold & Bismuth : After the removal of antimony, arsenic and tin, the softened lead may still containsilver and gold, and bismuth. The removal of the precious metals by the Parkesprocess is based on the fact that they are more soluble in zinc than in lead. In this process, the lead is melted and mixed with zinc at 480 °C. The temperature of the melt is graduallylowered to below 419.5 °C, at which point the zinc (now containing nearly all the silverand gold) begins to solidify as a crust on the surface of the lead and can be skimmed off.
  An alternative procedure, the Port Pirie process, used at the Port Pirie refinery in Australia, is based on similar metallurgical principles.

• Removal of zinc : The removal of the precious metals leaves zinc as the main contaminant of the lead.It is removed either by oxidation with gaseous chlorine or by vacuum distillation. Thelatter process involves melting the lead in a large kettle covered with a water-cooled lidunder vacuum. The zinc distils from the lead under the combined influence of temperatureand reduced pressure and condenses on the underside of the cold lid.
  Refined lead is poured into moulds and ingots are formed. These ingots are then sent to storage. For integrated Production of Lead Oxide, Refined Lead is casted into Balls. (to be fed directly to Lead oxide Ball Mill).

About Lead Refining :

Lead recycled from used lead acid batteries or other sources (Secondary Smelting) via the Mini Blast Furnace or Rotary Furnace route, contains lot of contamination and undesired components. On the other hand, Lead required for battery manufacturing is either soft Lead with 99.97% purity or hard Lead of varying Antimony compositions.In order to make quality of lead suitable for its different uses, different variations of pot melting processes are employed.

These includes :

• “Re-Melting” for removal of slag,
• “Refining” for attaining required purity levels and
• “Alloying” for producing various alloys of lead.

The equipment used is the same, the consumables and the processes, however, differ.

Refining Pot Details :

The Refining Pot (or Refining Kettle or Alloying Pot, as it is variously called), is a mechanical mixing device with a pot and a heating arrangement. The inner pot is made of heavy MS plate with dish end bottom. It is placed within a jacket of refractory bricks, which in turn, are protected by an outer cover of MS plate with reinforcements. The pot is covered at the top with opening for feeding lead ingots and is provided with an electro-mechanical mixer. At the bottom, a heating source, usually an oil fired/ Diesel burner& sometimes by Wood burning is provided to heat the pot and to melt the lead. Once lead melts, impurities are skimmed and removed and any consumables required are added. Lead is then drained from the pot through an outlet pipe and valve.

Capacity of such pots depends upon the requirements of particular units. Standard pot capacities made are from 3.0 Tons per Batch to20.0 Tons per Batch. Higher capacity pots are also manufactured as required by any particular establishment.

Melting pots are installed both with and without accessories which may include Ingot Casting Machine, Ball Making Machine (where Ball Mills are installed down the line), Air Pollution Control Systems, Jib Cranes etc.

Production Process :
Melting Processes have been grouped as

• Re-Melting Process
• Refining Process
• Alloying Process

Re-Melting Process : This process is undertaken for value addition to the recycled lead from furnaces. Lead is melted in the pot and major impurities are skimmed from it to make it saleable in the market.

Refining Process : Lead is melted in the pot, additives such as Sulphur, Wooden Powder and Coke Breeze are added and mixed gently followed by dross removal. Thereafter, Tin is added to remove Copper and temperature is increased to 550-6000C. Further, additives such as Sodium Nitrate & Caustic Soda are added to remove Antimony. This process is repeated to get the desired purity of lead.

Alloying Process : Lead is melted in the pot; additives such as Sulphur, Wooden Powder & Coke Breeze are added and mixed gently followed bydross removal. Thereafter, Tin & Antimony are added to the liquid metal to get the desired grade of Lead.


Melting processes lead to generation of air pollution at the following stages :

• Initial heating and melting generates fumes
• Drossing with sulphur, wooden powder and coke breeze generates lot of smoke and dust particles
• Further heating for Refining and Alloying with different chemicals generates fumes and dust particles.

Hence, to meet various goals of maintaining employees' health, factory environments as well as regulatory requirements, it becomes imperative to get high end Air Pollution Control Systems to be installed with the Melting Pots.

Characteristics of Air Pollution generated in Melting Pot :

• Dust : 500-600 mg/Nm3
• Temperature : 60-80° C
• Gases : Fumes and Dust

Discharge Characteristics required as per Norms :

• Dust - Less than 50 mg/Nm3
• Lead ( Pb) - Less than 10 mg/Nm3
• Temperature - 50-60° C
• Gases - Not Detectable

Selection & Detailson Technology for Air Pollution Control : Based on the Parameters and the Standards mentioned, the following technology is adopted for Air Pollution Control Systemin Melting Pot is Pulse Jet based Bag House Filtration System

Our Bag House Filters are reckoned to be highly efficient equipment to store filter bags in the desired way. These filters are 100% compliant with the applicable standards and are made from premium materials and components. Their design, structure, and performance is bound to surpass the expectations of our clients. And we have managed to carve a niche in the market as the reliable Manufacturer, Exporter, and Supplier of Bag House Filters from Uttar Pradesh, India. 

Details :
House is equipment which houses filter bags. It has two compartments separated by filter bags in such a manner that any of air stream passes through one compartment to another, that has to pass through Fabric Bag. One compartment is connected to in stream of flue gases and another to the inlet of Blower. Energy on the particles is exerted by pressure difference of both the compartments and flow of gases is created by Blower. Pressure drop in Bag House will depend upon Dust particle accumulated on the surface of bag fabric and no. of we have Bag House in cyclonic shape as well Rectangular Shape. Cyclonic Shape gives added advantage of filtration through fabric filters as well cyclonic separation. It reduces loading on Fabric Filter Bags.

Type of fabric depends upon particle and temperature. The filters retain particles larger than the mesh size. Air and most of the smaller particles flow through. Some of the smaller particles are retained due to interception and diffusion. The retained particles cause a reduction in the mesh size.  The primary collection is on the layer of previously deposited particles. Pressure drop will depends upon no. of bags. Higher no. of bags higher the filtration area, so lesser pressure drop is exerted.

We offer the Temple Furnace at the market leading. This Temple Furnace is known for its quality and long, hassle-free performance. A Mini Blast Furnace (commonly known as MandirBhatti or ShahiBhatti) is a simple, time-tested and widely used system to produce secondary lead in India and many other countries. It is the most basic of all furnaces and a production system based on this technology.

About Mini Blast Furnace
The Temple Furnace itself is a modified blast furnace which consists of a brick lined structure with fire brick oven in the midst and a metal Exo-skeletal structure outside. Raw material & fuel (coke) is charged manually through the side metal doors fitted in the brick structure and air is provided from the FD fans provided at the back of the brick structure. Molten metal & slag is tapped at the pits made in front of the brick structure and flue gases are sucked from the top of the brick structure which is provided with a metallic hood.

Lead to be manufactured from Mini Blast Furnace is usually obtained from scrapped batteries. They are cut open or broken to segregate lead scrap, plastic and other materials from it. Lead scrap in the form of lead powder and plates etc. is charged in the furnace along with a proportionate charge of wooden coke. Thereafter the furnace is manually fired with the help of rags. FD Fan provides the necessary air required for combustion from the back of the furnace. Coke in the oven performs the functions of both, the fuel as well as a reducing agent for obtaining lead from its oxides charged in the form of lead plates & Powder. Temperature of the furnace is maintained at the desired level for approximately 30 minutes, after which molten lead along with slag flows out from the bottom of the oven into the outlet pit. Here slag is separated and molten lead is poured into Ingot Molds. To maintain this, continuous charge of raw material and coke is maintained in the furnace. This process leads to generation of flue gases which are toxic in nature and need appropriate and adequate Air Pollution Control System for their treatment.

Temple furnace Is Of Two Types:

• Single Temple Furnace
• Double Temple Furnace

Characteristics

• Low Project Capital Cost
• Low Energy Cost (wooden coke fired)
• Easy to install
• Easy to operate & maintain
• Production of low Antimony Lead (soft lead) at low temperature
• Generates high pollution

Gas Neutralizing System for Air Pollution Control Device: Wet Scrubber

A Wet Scrubber in the Air Pollution Control System is mandatory in India and many parts of the world. Wet Scrubber uses water to scrub clean the flue gases of any pollutant gases or particles that may remain after Bag Filtration System. The Scrubber therefore requires a pump, pipeline and a retention tank. The size of the Scrubber depends upon the capacity of the system being installed. Flue gases are introduced in the body of the Wet Scrubber from side and as they move up towards the top of the Scrubber which has the outlet, they pass through a spray of fine water droplets provided by a spray shower provided in the body. This fine spray leads to scrubbing of any pollutant in the flue gases. Cleaned gases escape through the top opening after passing through a mist eliminator whereas water with pollutants moves to the bottom of the Scrubber from where it is passed into the tank. One or more chambers of the tank allow for settling of pollutants which are then periodically cleaned and fresh water is added to make up any loss in quantity of water. It is then recalculated to the Wet Scrubber.

[Note : Due to continuous up-gradation in technology, specified & projected values may differ in actual products.]

Ducts and Bends are required to convey flue gases from point of suction to final top of the chimney and connect with various pollution control equipment like gravity chamber, cyclone, bag house, ID Fan and chimney. We provide these Bag Filtration Systems at competitive rates.

Lead to be manufactured from Rotary Furnace can be obtained directly from scrapped batteries or as slag from Mini Blast Furnaces In case of former batteries are cut open or broken to segregate lead scrap, plastic and other materials from them; lead scrap in the form of lead powder/ plates etc. is charged in the furnace along with a proportionate charge of additives. In The case of latter, slag produced from Mini Blast Furnaces is charged into the Rotary Furnace, again with proportionate additives.

This process is a batch type process. After filling the required quantity of raw material (either manually or mechanically), the lid of the furnace at the front is closed. The burner attached to the moving door is then fired. 

The Rotary Melting Furnace is very flexible and universal equipment used for recycling many non-ferrous metals. It is the major lead production technology used in India and many other countries for Secondary Lead Production. A lead production system based on this technology has certain distinct characteristics such as :

• Equipment scalable for installing higher capacities
• Recovers all lead in one production cycle
• Plates & powder from scrap battery as well as slag from Mini Blast Furnace can be used as raw material
• Requires addition of certain consumables
• Can be fired with various fuels
• Generates high Pollution both as Flue Gases & Fugitive Emissions

Apart from plates and paste of lead oxide from scrap batteries, slag from Mini Blast Furnace is charged in the Rotary Furnace.

In addition to these, certain compounds of sulphur are also present in the batteries. When this material is heated in the Presence of carbon, lead oxide is converted to lead. This conversion along with burning of fuel generates flue gases and fumes containing dust, dirt, oxides of lead, lead particles and such other impurities etc.

Hence, to meet various goals of maintaining employees' health and factory environments as well as regulatory requirements, it becomes imperative to get high end Air Pollution Control Systems to be installed with the Rotary Furnaces.

Rotary Chamber Advantages :

• Recovers 100% lead in the first operation.
• Slag produced is lead free.
• Equipment can be scaled up for higher production capacities.
• Many chemicals are required for operation.
• High power consumption.

Rotary Furnace : 
We have two models of Rotary Furnace, one without barrel (Flame Shape) and another with barrel (furnace body). Both designs are advantageous, depending upon requirements. 

Barrel Type Rotary Furnace :
This is traditional design. Smelters have been using this type of furnace from very olden days around the world. But the final product is MIXED Lead (DOGALA Lead) and the recovery is also lesser as compared to our newly designed Rotary furnace. I will explain it in next paragraph. The reason for lesser recovery is cogging of slag into the tap out hole and In this turning process molten lead is mixed with slag and small amount of lead is retraped with slag so recovery is further reduced. So we designed Rotary furnace without barrel.

Rotary Furnace without Barrel or Flame Shape Rotary Furnace :
In this type of furnace, following advantages had been practically gained : 
Barrel type Rotary was designed for Iron Smelting, not for Lead, as we all know, thermal conductivity of Iron is very much different than Lead. Iron thermal conductivity is 80 while Lead thermal conductivity is 35 W/(m K). It considerably reduces with temperature. So, we increased L/D ratio of Furnace. This reduces temp. of exit gases, hence utilisation of energy is increased.

Current source of Machine is state of art heavy transformer of 65 KVA rating. We use best quality of copper, which dissipates lesser heat. So machine does not waste Costly electricity in the form of heat. Only Air-cooling is sufficient. If water-cooling is used it will increase running load of pump and wastewater, which has also becoming precious and harming to environment so our machine is environment friendly. At the same time reducing running cost of machine. It is designed indigenously as per need of our operator. This computer supply constant energy at constant current. Welding processes & parameters are controlled automatically & accurately by specially designed microprocessor. Operator can program 10 programs for different batteries. all parameters such as Squeeze Time, Weld Time, Cooling Time and required Current as per battery size, are fed to controller for battery size and recall whenever that size of battery is made. Operator can also see which operating time has been lapsed which other controllers do not provide. He can also communicate if any of the problems so he could be guided directly without physically present on the machine. If any type of problem arises it can be replaced repaired at nominal cost even after warrantee period.
