Cement kiln - Wikipedia
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.
Hammermill Crushers | McLanahan
The Standard and Non-Clog Industrial Hammermills are designed to reduce the material to a nominal 3" to 5" (75mm to 25mm) output. These are primary stage crushers, commonly followed with Centerfeed Mills or other types of secondary stage crushers. The HammerMaster is also a secondary stage crusher in that the maximum feed size is 6" (150mm).
