Active Lime Production Line

Lime Rotary Kiln is composed of cylinder, gears,support decvice, kiln liner and kiln tail sealing equiment, kiln head hood and combustion.Lime kiln as a heating device is a high-quality steel processed, is supported on the support device by tyre, and there is manchanical or hydraulic pressure catch wheel on the first or some gear in order to control the turning of cylinder.

Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger lime kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable kiln tail and hed sealing equipment is installed on feed and discharge end.

Working principle

Qualified limestone deposited in the hopper, the hoist lifting and transport into the preheater top hopper. Preheater top bin, composed of 2 level control the feeding amount, and then through the feeding tube will be evenly distributed to each limestone preheater chamber. Limestone in the preheater was 1150 degrees C kiln flue gas to heat to 900 degrees C or so, about 30% decomposition, the hydraulic push rod into the rotary kiln, the limestone in the rotary kiln through the sintering of CaO and CO2. After the decomposition of the limestone into the cooler, the cooler was blown into the cold air to 100 C.

By heat exchange of 600 degrees C hot air into the furnace and gas mixture combustion. The exhaust gas enters the bag type dust collector through the draught fan, and then enters the chimney through the exhaust fan. A cooler lime by vibrating feeder, bucket chain conveyor, bucket elevator, belt conveyor into lime storehouse. According to customer requirements for screening and other processes.
