  • BUILDING A SOLID FOUNDATION FOR YOUR MILL

    The grinding mill is at the heart of a mining operation, but a poorly designed or constructed foundation will not only affect grinding mill performance but potentially render the mill out of action thereby costing millions of dollars in lost production. The following advice will help ensure the foundation is right before you install a new mill.

  • 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.
