rotary kiln process for making calcium carbide

The cement rotary kiln is a cylindrical body with a certain inclination, and the inclination is 3 to 3.5%. The rotation of the kiln is used to promote the stirring of the material in the rotary kiln, and the materials are mixed and contacted for reaction. The combustion of the kiln head fuel produces a large amount of heat, and the heat is ...

    Preparation of CaO containing carbon pellets from coking

    CaO-containing carbon pellets (CCCP) were successfully prepared from well-mixed coking coal (CC) and calcium oxide (CaO) and roasted at different pyrolysis temperatures. The effects of temperature, pore distribution, and carbon structure on the compressive strength of CCCP was investigated in a pyrolysis furnace (350–750 C). The results showed that as the roasting temperature increased, the ...
