一、Kiln design and technical description of the process
Our new energy-saving and environmentally friendly lime shaft kiln adopts advanced shaft kiln design technology, and on the basis of absorbing and introducing the advanced design of foreign shaft kiln, we have carried out bold technological innovation, equipment improvement, and process improvement. After the innovation and improvement of our unit after the lime kiln shaft kiln, in energy saving, environmental protection, finished ash activity, automation and other aspects have been significantly improved.

1. principle
The main component of limestone is calcium carbonate CaCO3, while the main component of lime is calcium oxide CaO2. the principle of lime production is that at a high temperature of about 1150 ℃, the calcium carbonate in limestone decomposes into calcium oxide and carbon dioxide.
Lime production process is: limestone and fuel in accordance with a certain proportion of mixed into the lime kiln, when the limestone in the pre-tropical belt after preheating to 900 ℃ began to decompose, and then calcined belt calcination is the temperature reached 1150 ℃ to generate calcium oxide. After cooling belt cooling and unloaded from the kiln.

2. Automated control systems
The "environmentally friendly and energy-saving high-efficiency lime kiln" researched and developed by our institute. From electronic batching, lifting, automatic feeding, temperature control, air pressure, roasting, ash unloading, loading and transportation, all of them adopt microcomputer network control system, combined with human-machine interface control system and common computer control system. Achieved the man-machine interface and site synchronous operation, than the old lime kiln to save more than 50% of the labor force, improve production efficiency by 40%. Reduced labor intensity and improved working environment. After nearly several years of production and use shows that the kiln automation control system is reliable, low failure rate, greatly improving production efficiency and saving a lot of cost.
