In order to better promote and application of new active rotary kiln, accelerate the promotion of new energy-saving emission reduction technologies to improve the level of energy saving and environmental protection. Chaeng(Xinxiang Great Wall Machinery) 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, the kiln exports from the tail.

Chaeng product advantages:

1. advanced technology, high production efficiency, good quality lime

Lime rotary kiln produced by Great Wall Machinery 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 quality is very good, the lime activity is ≥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 stabilizing 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 lime production increased by 40% in steelmaking, but the activity of more than 300ml of high-grade lime from only 27% to 29.5%, low utilization rate, so good quality active lime production and the application prospect is huge.
