Industrial Quicklime Production Plant Machinery
Usage of lime in the lime plant/lime production line
Lime plant also can be named as lime production line, active lime processing, etc. Lime in lime plant can be divided into ordinary lime and active lime according to the nature. The degree of ordinary lime is generally less than 200ml, which is mainly used for building and repairing roads. Active lime has a high degree with the value of 300-420ml as well as with advantage of high porosity, high reaction, and low consumption in process, controllable process, widely applied to the steel smelting, calcium carbide, chemical industry, desulfurization and etc.
Main technical of quick lime plant/lime production line
The successful industry application of environment-friendly, energy-saving active lime stone with vertical preheated. Due to reduction of fuel consumption significantly and reducing exhaust emissions, coupled with the adoption of pulse-packs dust-catcher purify exhaust, not only makes production cost and the energy consumption greatly reduced, but also the calcinat ions process of emission standard, environmental condition is kept substantially.

Main advantage of quick lime plant/lime production line
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
Process Flow of 600tpd Active Lime Production Line
1. Raw Material Conveying:
The 20-40mm limestone on the stock ground is sent to storage silo by the belt conveyor with large inclination. In the storage silo, qualified limestone with granularity more than 10mm will be sent to the gravel silo, while limestone with particle size less than 10mm will be conveyed to the powder silo.
2. Limestone Calcining:
The limestone calcining system is mainly made up of 10.5x8.5m vertical preheater, 4.0x60m rotary kiln and vertical coolder whose output is 600t/d and heat consumption of 5.75GJ/t. Limestone inside the preheater is heated by high-temperature gases from rotary kiln to 600-800°C, at which temperature limestone can be partly decomposed. Then the limestone will be sent by 12 hydraulic push rods to the kiln end, where it will undergo high-temperature calcination before sent to the vertical cooler. The processed limestone will be cooled down by cold air to 65°C. Air from the vertical cooler enters into the rotary kiln as the second air to take part in calcining process.
3. Finished Product Conveying:
The final lime will be sent to the storage bin for final products by NE500 bucket elevator. After screening, qualified lime whose particle size is more than 5mm will be sent to storage for active lime, while powder lime whose size is less than 5mm will be sent to storage bin for powder.
4. Gas Treating:
High-temperature gases from rotary kiln will do heat exchange with limestone inside the preheater, and after that, the temperature of these gases will reduce to lower 280°C. Then these gases will be cooled down by multi-tube cooler to 200°C lower. Finally, they enter into the bag filer before discharged into the atmosphere
