Product description

The cement clinker rotary kiln is the main equipment for cement clinkers calcining in chemical industry, metallurgy industry, etc. Through technological innovations, the calcination system of this cylindrical calcinator has been equipped with the most advanced hydraulic thrust roller in the world and various advanced devices in China, including highly accurate measuring plunger pump, greatly precise compensated flow control valve and contact-type graphite sealing device, etc.

Cement clinker rotary kiln in operation process, over time the parts will be wear and tear, thus reduce reliability during equipment operation, and even affect the production of rotary kiln, therefore must borrow overhaul chance to recover. According to the maintenance work load, overhaul, repair, and minor repairs. The use of factory according to the operation and maintenance of rotary kiln for large, medium and minor repair plan. Focus on small repair and obtained.

Structural principle

Rotary clinker kiln is the main equipments of cement production host. Mainly include the kiln cylinder, driving device, supporting device, thruster device, kiln head seal device, kiln tail seal device,kiln hood and other parts. Raw material from high-end of kiln tail cylinder feed in kiln cylinder.Due to the kiln cylinder¡¯s gradient and slowly rotating, the material produces a rolling along peripheral direction, and a movement along the axial from high side to low side compound movement, raw meal by decomposing, sintering and other process, after calcining turn to cement clinker from the kiln cylinder low-end out, discharged into the cooler. Fuel injects from the kiln head, burning in kiln and generate heat to heat raw meal, make raw meal turn to clinker by calcine, hot air forms from the heat exchange process with material, the kiln¡¯s feed-end entering in kiln tail system (preheater and dust collector), and finally by the chimney discharged into the atmosphere.

Technical advantages

1.High quality steel, temperature resistance and anti-cracking

2.Big gear structure strong, stable operation

3.Big Kiln speed ,high capacity
