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. 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 by dross removal. Thereafter, Tin & Antimony are added to the liquid metal to get the desired grade of Lead. Air Pollution Control Device for Refining Pot 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. Air Pollution Control Device for Refining Pot Dust : 500-600 mg/Nm Temperature : 60-80C G Gases : Fumes and Dust Discharge Characteristics required as per Norms Dust : Less than 50 mg/Nm Lead ( Pb) : Less than 10 mg/Nm Temperature : 50-60 C Gases : Not Detectable Selection of Technology for Air Pollution Control Based on the Parameters and the Standards mentioned, the following technology is adopted for Air Pollution Control System in Melting Pot: Pulse Jet based Bag House Filtration System Details of Air Pollution Control Device with functions Aerodynamically designed suction hoods are provided to capture flue gases generated at source itself.

A fire alarm system is a set of electric/electronic devices/equipment working together to detect and alert people through visual and audio appliances when smoke/fire is present. These alarms may be activated from smoke detectors, heat detectors, water flow sensors, which are automatic or from a manual fire alarm pull station. Types of Fire Alarm System: All Fire Alarm Systems essentially operate on the same principle. If a detector detects smoke or heat or someone operates a break glass unit (manual break point), then alarm sounders operate to warn others in the building that there may be a fire and to evacuate. It may also incorporate remote signaling equipment which would alert the fire brigade via a central station. Conventional Fire Alarm System In a Conventional Fire Alarm System, a number of call points and detectors are wired to the Fire Alarm Control Panel in Zones. A Zone is a circuit and typically one would wire a circuit per floor or fire compartment. The Fire Alarm Control Panel has a number of Zone Lamps. The reason for having Zones is to give a rough idea as to where a fire has occurred. This is important for the fire brigade and of course for the building management. The accuracy of knowing where a fire has started is controlled by the number of Zones a Control Panel has and the number of circuits that have been wired within the building. The Control Panel is wired to a minimum of two sounder circuits which could contain bells, electronic sounders or other audible devices. Each circuit has an end of line device which is used for monitoring purposes. Addressable Fire Alarm System The detection principle of an Addressable System (Fire Alarm System) is similar to a Conventional System except that the Control Panel can determine exactly which detector or call point has initiated the alarm. The detection circuit is wired as a loop and multi devices may be connected to each loop. The detectors are essentially Conventional Detectors, with an address built in. The address in each detector is set by dil switches and the Control Panel is programmed to display the information required when that particular detector is operated. Additional Field Devices are available which may be wired to the loop for detection only i.e. it is possible to detect a normally open contact closing such as sprinkler flow switch, or a normally closed contact opening. Fire Alarm System comes with single loop as well as multi loops. It depends on requirement. The items which are integrated with Fire Alarm Systems are given belowâ?¦. Brands are available : AGNI, MORLEY, NOTIFIER, Modern Technologies gives you top class branded Fire Alarm System with affordable price. We also provide installation & maintenance services.
