The whole production process of cement is summed up as "two grinding and one burning", in which "one burning" is the process of burning raw meal prepared by grinding into clinker under the high temperature of cement rotary kiln. The cement rotary kiln equipped by our company has a certain inclination between the kiln body and the horizontal. The whole kiln body is supported by a supporting wheel device, and there is a stop wheel device to control the up and down movement of the kiln body. In addition to the main transmission, the transmission system is also equipped with an auxiliary transmission device which can make the kiln body rotate and prevent the kiln body from bending and deformation when the main power supply is interrupted. The sealing device of kiln head and kiln tail adopts advanced technology The reliability of the seal is guaranteed. The production line has been installed up to now, with reliable operation and large processing capacity. The production process is divided into dry production and wet production, which can be selected according to the specific needs of users.
