Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
The OK mill design uses the same swing lever and roller assemblies for either cement or raw applications. It also allows the ability to continue using the unique grinding roller profile of the OK cement mill and an optimised spherical grinding profile for raw grinding applications. The rollers are in a lifted position when the mill is started,
