About Mini Blast Furnace A Mini Blast Furnace (commonly known as Mandir Bhatti or Shahi Bhatti) 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 has certain distinct characteristics such as: 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 Description of Mini Blast Furnace The 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. A typical Double Oven Mini Blast Furnace has the following standard sizes & specifications: Outside Dimensions of Brick Structure: 2400mm L x 1900mm W x 2400mm H No. of Ovens: 2 Nos. Oven Size Top Dia: 600mm Bottom Dia: 250mm Depth: 650mm No. of FD Fans: 2 Nos. (1 for each oven) FD Fan Capacity: 300cmh at 250mm of WG No. of Charging Doors: 2 Nos. (1 for each oven) Charging Door Dimensions: 1100mm H x 650mm W Advantages No consumables used other than Wooden Coke which is also used as Fuel Low Power Consumption Produces low Antimony Lead suitable for soft lead purposes Pollution can be controlled with minimum fugitive emissions Easy to install, operate & maintain Disadvantages Cannot recover 100% lead in the first operation Subsequent recovery of lead after first recovery consumes higher coke & manpower. Equipment cannot be scaled up for higher production capacities. Air Pollution Control System for Mini Blast Furnace Various types of lead present in used batteries, plates and paste of lead oxide are charged in the 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 other impurities etc. Hence, to meet various goals of maintaining employees' health, for factory environments as well as regulatory requirements, it becomes imperative to get high end Air Pollution Control Systems to be installed with the Mini Blast Furnaces.
About Rotary Furnace The Rotary Melting Furnace is a 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 Description of Rotary Furnace It is a Rotary kiln in the form of a metallic cylinder with conical sides on both ends. Mild steel plate is used for construction of this shell and its thickness varies depending upon the capacity of the equipment. This shell is rotated on its own axis at 1-2 rpm. For this purposes tyres (also called riding rings) are fitted on the shell. These are fabricated from MS squares or flats, machined for a smooth finish. These tyres ride on steel rollers which are again machined finely. These rollers are fitted on a robust MS structural frame and driven by a gear & motor arrangement. The shell is lined inside with insulation and fire bricks of suitable Alumina content. Conical ends of the furnace are open on both sides. The furnace is charged with Raw material along with additives from the front end. This side is provided with a movable door on which a burner is mounted. The burner can be a conventional one or a fully automatic one depending upon the fuel used. At the other end, an exhaust block lined with refractory bricks is provided. A tapping hole is provided in the center of the shell from where molten metal & slag are discharged. Flue gases generated are sucked from the exhaust block side of the furnace. A typical 3.0 TpB Rotary Furnace has the following standard sizes & specifications : •Outside dimensions of the Rotary •Shell dia : 2075mm •Shell length : 2500mm •Total length : 4500mm •Charging dia : 450mm •Exhaust side dia : 450mm •Refractory thickness : 200mm •Fuel : Furnace Oil •Burner : Model 4 A Make: Wesman with complete assembly •FD Fan capacity : 550 cmh at 44mm of WG •Gear Box in drive : 8”, 1:40 Ratio •Motor in drive : 15.0 HP x 960 RPM •Structure used for base : ISMC 250 x 80 Advantages •Recovers 100% lead in the first operation. •Slag produced is lead free. •Equipment can be scaled up for higher production capacities. Disadvantages •Many chemicals are required for operation. •High power consumption. •Difficult to produce low Antimony lead suitable for soft lead purposes. •Fugitive Emissions need to be captured in addition to flue gases. •Need skilled operators and careful maintenance.
UNIVERSAL TILTING ROTARY FURNACE (UTRF) for Lead recycling the above mentioned photograph under production capacity 10 ton/batch. Universal Tilting Rotary Furnace is designed like a rotary closed well furnace. It has advantages of rotary furnace, rebvetory furnace and dry hearth furnace in a single equipment. Main advantage of UTRF is that it can be rotated as well as tilted. Firstly lead scrap is loaded in furnace with smelting flux and furnace locked. The material is heated with the help of oil/gas burner which is mounted on the door, until it reaches melting point. Heating is immensely faster because of horse shoe flame design. Due to the quick heating, consumption of oil and melt loss is very less as compared to the conventional tube furnace. Merits of Universal Tilting Rotary Furnace: 1. Less amount of flux is required for melting. 2. Efficient working condition. 3. All non-ferrous scrap can be recycled in a single unit. 4. Homogenous charge resulting in high quality of material. 5. Self-cleaning of lining. 6. Recurring cost is approximately 30% less as compared to horizontal rotary furnace. 7. Ensures faster melting rate. 8. Better yield. Comparison between UTRF and Horizontal fixed axis Rotary Furnace: The traditional furnace (fixed axis rotary furnace) is primarily a rotating tube with burner on one end and flue at the other. The furnace functions under negative pressure and gets cold air from outside making it virtually impossible to control the atmosphere in the furnace, which is nearly always oxidizing (air rich). It view of it, large amount of flux is required to protect the charge. Consumption of oil is also high because travel length of flue gas is less. On the other hand, UTRF furnace is designed with a single entrance and exist point. The door carries burner and flue. The furnace operates under positive pressure and during firing of the burner there is complete absence of cold air from outside resulting in reduced amount of flux required during operation. In addition the furnace operates at an angle, the charge is mixed with similar action that of a concrete mixing machine. This improves homogeneity heat transfer resulting in high thermal efficiency. Salient Features of Universal Tilting Rotary Furnace: 1. Tap to tap cycle time 4- 5 Hrs. 2. Energy consumption 600 Kw/MT 3. Robust steel structure with proven drum 4. Life of refractory lining is long 5. Oversize driving system and bearings. 6. Tilting, door opening and closing is hydraulically operated. 7. Sturdy interlocks for safety of the equipment. 8. Less manpower required. Only two persons per shift can operate the furnace.
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 include – “Re-Melting” for removal of slag, “Refining” for attaining required purity levels and “Alloying” for producing various alloys of lead. The equipments used are the same, the consumables and the processes, however, differ. Description of Melting Pot The Melting Pot (or Refining Pot 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 burner, 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 4.0 TpB to 20.0 TpB. Higher capacity pots are also manufactured as required by any particular establishment. A typical 10.0 TpB Refining Pot has the following standard sizes and specifications: •Diameter (ID) : 1150mm •Height : 1250mm (+Dish Depth of 200mm) •Flange Width : 350mm •Outer Shell Diameter : 1900mm •Stirrer MoC & Dia : SS-304 & 75mm •Stirrer Motor : 5.0 HP x 960 RPM •Outlet Valve Size : 40mm •Burner : Diesel Fired •Fuel Consumption Range : 8-18kg/ltr 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.

Battery crushing and hydro separation Battery crushing and segregation plants are required for handling of large volume of battery scrap to feed smelting units. In this automated system, batteries of all sizes are loaded on conveyor and fed into hammer mill. Batteries are crushed into small pieces and particles are collected at the bottom of hammer mill in a container. The container is already filled with water solution of specific gravity. The plastic material floats on the top of water solution and lead bearing scraps settles at the bottom in the container. The plastic is removed from the top with the help of water jet system. The bottom of container is fitted with screw conveyor for discharge outlet for lead bearing scrap. The lead bearing scrap is conveyed through screw conveyor to a vibrating screen, where large particles are retained and collected. They are further dried and used as raw material for smelting unit. The fine particles at the bottom of container are kept in agitation and after that passed through filter press to form a cake. This cake is further dried and used as a raw material for smelting unit. The plastic material is collected, washed further for processing. The portion of waste water is taken into treatment plant and similar amount is replaced with fresh water. There are very few battery crushing and hydro separation units installed with corporate groups. It is not viable for small and medium scale units because of high capital investment. Gradually parties are interested to install battery crushing and hydro separation units since it is mandatory to have same for import of used batteries in india.
