Used Mini Small Dust Gypsum Incinerator Activated Carbon Kiln, Lime Roller Rotary Kiln Machine Price For Sale, Mini Small Gypsum Incinerator
1. Introduction of Mini Small Dust Gypsum Incinerator Activated Carbon Kiln
Lime rotary kiln are used for produce active lime and light burned dolomite used in steel roasting plants and ferroalloy Factory.
Lime kiln main subsidiary equipment are feeding mechanism, distributing device, wind supply device, burning device, ash discharging device, etc. Relatively speaking, co-firing lime kiln material distributing is very critical because it feed the fuel and limestones into kiln simultaneously, and must achieve burden are reasonable distribution in the kiln, eliminate the furnace wall effect, balanced resistance in furnace, to achieve whole furnace section of "lit" uniform. Therefore, the form and effect of distributor has a great influence on the productivity of lime kiln.
2. Advantages of Mini Small Dust Gypsum Incinerator Activated Carbon Kiln
1. Good quality and high output, suitable for large-scale activity of lime production line and large-scale production.
2. Stable production, all the production with the negative pressure, air flow and higher security.
3. Simple structure, easy control and beneficial operation and maintenance.
4. Fine grade limestone can be calcined, full use of mine resources.
5. Low heat consumption per unit of product, installation in vertical kiln perheater which can take advantage of exhaust warm limestone, greatly reducing the fuel consumption.
6. Making full use of industrial waste gas as a fuel for lime burning (such as blast furnace exhaust gas, acetylene tail gas, charcoal blue exhaust, etc)
7. Kiln head adopts the design of vertical cooler integrating kiln head cover. The construction area is small, good sealing, effectively avoiding hot waste gas emissions unsystematically.
3. Features of Mini Small Dust Gypsum Incinerator Activated Carbon Kiln
Active lime kiln has advanced structure. The vertical pre-heat with low-pressure loss can effectively improve the pre-heating effect, and the in-kiln decomposition rate of the pre-heated limestone can reach 20-25% and the 10-15mm fine particle limestone materials can be directly used.
4. Principle of Mini Small Dust Gypsum Incinerator Activated Carbon Kiln
Qualified limestone is stored in the silo, the upper and lower level gages control feeding amount, and then through the tremie pipe, limestone is evenly distributed into every chamber of the preheater.
Limestone in the preheater is heated by 1150 degrees Celsius to 900 degrees Celsius, about 30% is decomposed, hydraulic pusher push them into the rotary kiln, the limestone in the rotary kiln is roasting and decomposed into CaO and CO2.
After decomposition, generated lime enters into the cooler, in the cooler blowing cool air cool the lime to below 100 degrees Celsius and is discharged. 600 degrees Celsius hot air through heat exchange enters into the kiln and with gas fuel combination. Exhaust gas is added cool air blast and by the draught fan, enters into the bag filter, and then discharged through the exhaust fan into the chimney. By vibrating feeder, chain bucket conveyor, bucket elevator, belt conveyor, the lime discharged from the cooler enters into the lime reservoir. According to the user's needs to determine whether proceed screening processes.
In the lime roasting system, in accordance with output, the preheater is divided into several preheaters, every preheater is matched with a set of hydraulic pusher device, and matched with automated control systems, which can send related datas into central control room's PLC control platform to realize centralized control. This system has high degree of automation and can achieve single point controlled to make the production process more convenient.
