Cement Lime Rotary Kiln

Products Detail

Cement lime rotary kiln is mainly used for calcining cement clinker. Cement lime recycling kiln includes: dry process cement rotary kiln, semi-dry process cement rotary kiln, wet process cement rotary kiln. New dry process cement rotary kiln series products are mined by adopting advanced technology. The rotary kiln is driven by the rotary kiln cylinder through the transmission device to rotate and continue to heat the clinker at a high temperature. It meets the heat exchange requirements of each stage of clinker formation. For different mineral formation heat, temperature, time and other specific requirements. The kiln body is made of refractory bricks, castables and special steel plates.  

The rotary kiln is the main equipment for cement production. The overall structure consists of: cylinder, rotating device, supporting device, sealing device, feeding system, cooling discharge system and other components. Raw meal is fed into the kiln cylinder through the high end of the kiln end cylinder. Due to the tilt and slow rotation of the cylinder. The boring is turned over along the direction of the surrounding. Along the axial direction from the high end towards the low end to move compound movement. Raw material is produced in the kiln through decomposition and calcination to get that process. It is burnt into cement clinker and discharged from the low end of the kiln cylinder into the cooler.

Fuel is fed from the kiln head. Combustion takes place in the kiln and the heat emitted heats the raw material. The raw lime material is calcined to make clinker. The material heat exchange process forms hot air. The kiln feed end enters the kiln end system. Afterwards it is discharged into the atmosphere by the chimney.

Raw Materials

Calcined cement, activated lime, nickel, iron, lithium, chromium, etc.  

Advantageous

1. High-quality steel, temperature-resistant and crack-resistant. The kiln body is made of high quality carbon steel or alloy steel plate rolled and automatically welded.

2. Advanced technology, kiln speed increases, unit volume and output increase.

3. the big gear ring is connected with the kiln cylinder through tangential spring plate, the big gear structure is strong and smooth operation.

4. good sealing effect, full use of preheating, environmental protection and dust removal are simple and effective, achieving high clinker quality and low energy consumption

5. long service life of kiln, high operating rate, high heat transfer efficiency, high unit volume

6. Equipped with automated PLC control system, real-time monitoring and control can be realised.
