What are the specialized equipment for new mechanical lime kilns
The new mechanical lime kiln adopts automation, energy-saving and environmental protection technology, and its core equipment includes raw material processing, calcination system, waste gas treatment and automation control. The following are the main specialized equipment:
1. Raw material pretreatment equipment
Crusher: used to crush limestone to the appropriate particle size (usually 30-50mm).
Screening machine: Remove impurities to ensure uniform distribution of raw materials.
Conveyor system: belt conveyor or bucket elevator, used for conveying raw materials to the preheater.
2. Core equipment of calcination system
Preheater: Utilizing kiln exhaust gas to preheat raw materials and improve thermal efficiency.
Rotary kiln or vertical kiln: New mechanical kilns often use energy-saving rotary kilns or double chamber vertical kilns with calcination temperatures of 900-1200 ℃.
Combustion system: including gas/coal powder burners, supporting low nitrogen combustion technology.
Cooling machine: Quickly cool lime and recover waste heat for preheating or power generation.
3. Environmental protection and waste gas treatment equipment
Dust collector (bag/electrostatic precipitator): reduces dust emissions.
Desulfurization and denitrification device: reduces SO ₂ and NOx emissions, in compliance with environmental standards.
Waste heat recovery system: Utilizing exhaust gas thermal energy to generate electricity or heat, improving energy utilization efficiency.
4. Automated control system
DCS/PLC control system: Real time monitoring of temperature, air volume, production and other parameters to optimize the calcination process.
Intelligent detection devices, such as infrared thermometers and gas analyzers, ensure stable production.
The new mechanical lime kiln achieves modern production with low energy consumption, high output, and low emissions through efficient and environmentally friendly specialized equipment combinations.
