In order to cope with the crisis caused by environmental pollution, Great Wall Machinery has more than 50 years of large-scale rotary kiln production experience, in order to keep up with international pace, improve product technology and competitiveness level, Great Wall Machinery launched an upgraded version oflime rotary kiln, won the majority of customers Favored. At the same time gradually the development of general contracting services, can undertake Nissan 200-1500 tons ofActive Lime Production Line "turnkey project" service.

Lime Production Line Processing:

Qualified limestone (20 ~ 50 mm) are lifted by bucket elevator to top silo of preheater.

There are two level indicators (up and down) controlling the feeding amount, then they are separated averagely into preheaters’ individual rooms. The limestone’s temperature rises to about 900℃ heated by kiln flue gas of 1150℃, about 30% of them are decomposed, and they come into the lime rotary kiln by hydraulic rod, where the limestone decomposed into CaO and CO2.

The decomposed limestone are put into the cooler, where its temperatures drops to 100℃ and released. The hot air (600°C) will come to kiln after heat exchange, and mix with coal gas for mixture combustion.

The exhaust gas is released by the blower into bag deduster through multi-pipe cooler, then into the chimney though exhaust blower.

Active lime production line income:

Activated lime is an important auxiliary material for steelmaking. The use of activated lime has a series of characteristics such as improving the quality of molten steel, increasing production, reducing steel consumption and cost, and stable operation. Where the use of active lime steelmaking enterprises have achieved significant economic benefits.
