CHAENG Lime rotary kiln production to meet the national environmental requirements
In order to promote and application of new active lime production line, accelerate the promotion of new energy-saving emission reduction technologies to improve energy-saving environmental protection level. CHAENG positive response to environmental pollution-free policy for the production of lime kiln to strictly control.
CHAENG lime kiln process description:
Material from the kiln (cylinder of the high-end) into the kiln calcination. Due to the tilting and slow rotation of the cylinder, the material moves both in the circumferential direction and in the axial direction (from the high end to the low end), continues the process of decomposition and sintering, undergoes physical and chemical changes, Material by the kiln hood into the grate cooler cooling. Fuel from the kiln head into the kiln, the combustion of waste gas and heat exchange of materials, derived from the kiln.
CHAENG mechanical advantages:
1. Advanced technology, high production efficiency, good quality lime
The Lime Rotary Kiln produced by the CHAENG adopts advanced vertical preheater with advanced structure and low pressure loss, which can effectively improve the preheating effect and improve the production efficiency. The lime produced is very good and the lime activity is more than 300 ml. The ideal energy-saving environmental protection lime kiln equipment.
2. Energy-saving calcination, advanced calcination mechanism
Furnace design uses fully sealed calcination mechanism, the kiln fire-resistant insulation layer using multi-layer refractory, mild, furnace insulation design life of more than 5 years. In order to effectively use energy, the upper and lower part of the furnace using heat exchange way, greatly reducing the heat from the top and bottom of the loss.
3. Using the inverter, energy-saving equipment operation
The lime kiln used in the production of power are used in the inverter control and operation, to avoid a large horse-drawn car and no load no-load operation of the phenomenon, saving an average of 40% or more.
Lime rotary kiln Investment income:
Active lime is an important auxiliary raw material for steelmaking. The use of active lime has a series of features such as improving the quality of molten steel, increasing production, reducing steel consumption and cost, and stable operation. Where the use of active lime steel-making enterprises have achieved significant economic benefits.
The data show that over the past decade, China's steel lime production increased by 40%, but the activity of more than 300ml of high-grade lime from only 27% to 29.5%, low utilization rate, so good quality lime production And the application prospect is huge.
