Lime can be divided into two types: ordinary lime and active lime. The former is mostly fired in earth kilns and ordinary shaft kilns, and its activity is generally within 200ml, which is mainly used for construction and road repair; the latter is mainly composed of mechanical shaft kilns and rotary kilns. After calcination, the activity can reach 300~420ml. Limes calcined in rotary kilns are of better quality, and they are mainly used in industries such as steel smelting, chemical industry and power plant desulfurization.
Raw Material: The particle size of limestone is required to be 10-40mm, and the part exceeding the upper limit of 40mm and the lower limit of 10mm shall not exceed 5%.
1. The combustion equipment uses energy-saving burners to automatically control the air distribution volume to reduce the loss of incomplete fuel combustion.
2. Rotary kiln refractory bricks adopt light-weight insulation on the outer layer and composite bricks with refractory and wear-resistant inner layer to reduce heat dissipation from the outer skin of the rotary kiln.
3. There is a vertical preheater at the end of the rotary kiln, which makes full use of the high-temperature flue gas produced by the combustion of the rotary kiln to preheat the materials in the preheater, so that the materials are partially decomposed in the preheater.
4. A vertical cooler is installed at the head of the rotary kiln to make full use of the heat contained in the high-temperature calcined white material of the rotary kiln to preheat the secondary air to 600°C, which improves the thermal efficiency. Yaotou mining
5. The vertical cooler and the kiln hood are integrated in the design and construction, which has a small footprint and good sealing, which effectively avoids the fugitive emission of hot exhaust gas.
6. The kiln tail is environmentally friendly and dust collection is good. The cyclone dust collector and pulse bag filter are used for secondary dust removal, and the emission concentration is lower than the standard.
7. The level of automation is high. The adjustment, control and alarm of the production system are controlled by PLC in the main control room. There are few on-site operators and high labor efficiency.
