Clinker Production
Cement kiln is the main equipment for clinker sintering. From structure, it can be divided into rotary cement kiln and shaft kiln, while, from the working principle, it can be divided into the dry method and wet method kiln. AGICO offers different types of cement kilns from 10-5000t/d with steady running, high efficiency and large output.

FOR CEMENT RAW MATERIAL
14 mills Type LM 69.4 and LM 69.6 with product throughputs of up to 1200 t/h are sold. In the 1930s Loesche mills are used to grind cement raw material for the first time. The major breakthrough came at the start of the 1960s when rotary kilns with heat exchang - ers (dry process) are introduced.
