Annual production of 200000 tons of active lime rotary kiln project (China)
Raw material: Limestone (CaCO3 ≥ 93%, particle size 10-40mm).
workmanship
Limestone → Preheater (using kiln tail gas) → Rotary kiln (1200 ℃) → Grate cooler → Finished product (CaO ≥ 92%)
Energy consumption: Standard coal consumption: 115kg/ton of lime.
Electricity consumption: 25kWh/ton of lime.
Environmental protection: flue gas desulfurization (dual alkali method, SO ₂<100mg/m ³).
The dust recovery rate is greater than 99%.
