It is well known that, with the infrastructures greatly development, highway building material has the larger demand which including the cement mineral ,concrete and other highway building materials.

Although cement plants generate the same final product using similar processes lant layouts vary according to fuels and raw materials used, location, climate, site topography,and the manufacturer of the equipment. highway building material process including the gravel mobile jaw crusher as the primary crushing plant, the cone crusher as the secondary crushing machines, then the cement raw material, our gravel mobile jaw crusher has many capacity which range 100tpd-1000tpd capacity.

After the primary crushing process, The clinker cooling operation recovers up to 30% of kiln system heat, preserves the ideal roduct qualities, and enables the cooled clinker to be maneuvered by conveyors.  The mostcommon types of clinker coolers are reciprocating grate, planetary, and rotary.

Air sent through he clinker to cool it is directed to the rotary kiln where it nourishes fuel combustion.  The fairly coarse dust collected from clinker coolers is comprised of cement minerals and is restored to he operation.  Based on the cooling efficiency and desired cooled temperature, the amount of air used in this cooling process is approximately 1-2 kg/kg of clinker.  The amount of gas to be cleaned following the cooling process is decreased when a portion of the gas is used for other processes such as coal drying.
