CHAENG has an experience of successfully executing numerous complete Rotary Kiln Cement Green Field Projects, Cement Rotary Kiln Plant and Rotary Kiln Turnkey Cement Plant.

The raw meal from storage silo is conveyed to preheater by elevator or air lift. Preheater are generally 5 stages or 6 stages according to plant capacity and degree of calcination required.

Each stage of Preheater consists of fabricated Cyclones and connecting gas Riser ducts. Cyclone and Riser ducts are specially shaped to have smoother flow, good collection efficiency with lesser pressure drop.

The calcined material from preheater is then fed to kiln where it is further calcined and sintered. The Clinker coming out kiln is cooled in grate cooler and is stored in clinker silo.

Rotary kilns systems have evolved considerably in form and complexity over the last 120 years, but the kilns themselves have certain common features.
