Argon oxygen furnace is a kind of refining furnace, which is characterized by side-blowing oxygen through the bottom tuyere with an immersion way. When the tuyere center is blown in with oxygen, argon and mixed gas of nitrogen, the proportion of argen and oxygen should be adjusted, then, it can achieve the purpose of decarburizing and retaining of chrome. Argon and nitrogen are used as cooling gas for tuyere ring to extend the life of tuyere. It can get the best operation by controlling the flow of the tuyere ring. And the flow of the tuyere center and tuyere ring can be controlled in master-control room. The burning loss of tuyere, refractories and chrome is influenced greatly by the temperature of molten steel. So we can offer a special online temperature measuring system to buyers. We adopt secondary combustion of top lance technology. It can increase the volume of cold material put into the vod and shorten the duration of smelting, and guarantee the continuous casting for multiple furnaces at last. We also use the charging system with a weigh on its multiple bunkers, which can be directly connected with control system of computer. Then the smelting cycle will be shortened and labor intensity will be reduced. This equipment has a control system of intellectualized smelting process, which can decrease the consumption of all kinds of raw materials and gas during the smelting, and guarantee a stable quality of products. New security design for smelting It is aiming at the plugging of lance and the back-flow of molten steel which caused by electricity interruption during smelting process. Aod series refining furnaces have a function to keep pressure of tuyere and contain uninterruptable power output to stop the above accidents, consequently improve the safety of smelting process.

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 Manufacturing Process 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 Moulds. 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. Process Details for a typical Double Mini Blast Furnace Raw Material Charged 700-800 kg hr. Fuel used Wooden Coke Calorific Value of Fuel used 4000-5000 kCal kg Fuel Consumed 70-75 kg hr. Air provided for process 300 cmh Lead Produced (1st Charge) 300-350 kg hr. Flue Gas generation 8000-9000 cmh Advantages and Disadvantages of Mini Blast Furnace 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. 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.

Rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas. Rotary dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The rotary dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through rotary dryer under gravity. Material to be dried enters the dryer, and as rotary dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industrial and coal slime in coal mine etc. Rotary dryer can be widely used to dry sludge, sand, coal, gypsum, sawdust, mineral slag, sludge, chicken manure, and it is simple to operate.

Coal dryer is now hot equipment in the world. Coal is vital energy resource in various industries and daily life. When coal is washed or stored in open yard, some is washed away which forms coal slime later. This is a great loss. Coal slime is of high moisture and low heat, which means poor economic value. However, coal dryer solves this problem perfectly. Under normal conditions, moisture inside of coal slime is 20-30%. After drying, the moisture can be reduced to 0.1%. Thus, coal slime can be used in many occasions. Coal dryer turns waste into treasure. How does coal dryer work? Coal dryer is divided into several sections for higher efficiency. A. Transmission section. Wet material enters coal dryer, then it gets full contact with hot air, moisture inside gets vaporized. With lifting boards elevating and scattering materials repeatedly, wet material is conveyed to next section. B. Cleaning section. When materials fall down, they are easy to stick on the inner wall of the cylinder. During this process, cleaning device breaks the clumps. This spreads the surface area of heat exchange and improves heat efficiency. C. Lifting boards section. Wet material gets loose and of low moisture content that meets the requirement. D. Discharging section. No lifting boards in this area. Materials roll to the outlet coal dryer. The whole drying process is completed. Diameter of cylinder 1.2m Length of cylinder 10m
Sand dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas. Sand dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. Sand dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters sand dryer, and as sand dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of sand dryer. When material gets high enough to roll back off the fins, it falls back down to the bottom of sand dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case sand dryer is called a direct heated dryer. Diameter of cylinder 1.0m Length of cylinder 8m
