The cement industry in the development process in different production methods and different types of rotary kilns, raw material preparation methods can be divided into the rotary kiln is divided into dry rotary kiln dry production and wet production, and production methods compatible rotary kiln two types of wet hair. raw materials characteristics required for the cement production differ at a wide range. The cement deposits used today as base material, show very different properties regarding hardness, abrasiveness and stickiness. liming heavy industry different types of crushers are available to crushing process as well as the investment and operating costs. To make a proper selection, several important points should be considered in advance.

　　Jaw  crusher and Gyratory/Cone crushers reduce the material by high pressure, which makes them perfect for processing hard materials with a compressive strength of up to 400 Mpa. Because of the relatively low compressive strength of limestone (< 150 Mpa), these crushers are mainly used for highly abrasive limestone. On the other hand these machines are sensitive to high moisture contents, which have to be considered very carefully.

　　Liming heavy industry vertical shaft Impact Crushers With the introduction of vertical roller mills, which accept a raw material size of up to 80mm, the　Impact Crusher became of prime importance for the cement industry. Modern Impact Crushers are equipped with heavy duty rotors in common rail design. Specially designed cast discs are combined　on one main shaft, concentrating the main weight at the circumference of the rotor. The result is a high moment of inertia and kinetic energy, which allows one-step crushing of the raw material down to　the required product size.

　　Although the materials used for the cement production are quite different regarding hardness, abrasiveness and stickiness, there is a wide range of crushers and crushing systems available, meeting all requirements. They allow the optimization of each crushing process and thus a minimization of investment and operating costs. As about the question how to crush limestone, liming heavy industry provide a complete set of limestone crushing production line. Our limestone crushing process solution has three stages: primary crushing, secondary crushing and tertiary crushing.
