In industrial production, rotary kiln machine as the key equipment of cement calcining has the main function: as a fuel burning device, it has a vast space and thermal field, so that can provide enough air, and equipped with excellent combustion device to ensure the fuel full combustion in the rotary kiln machine. Energy-saving active cement rotary kiln process can be divided into material systems and air systems.

materials system is: the raw materials in the warehouse is delivered by vibrating feeder, belt scale, conveyor screening equipment, and finally through the conveyor to be transported into the preheater.Exhaust air discharged from the vertical preheater, through high-efficiency heat exchanger to preheat the primary air and reduce the exhaust gas temperature, the preheated primary air into the cement rotary kiln for combustion-supporting. The airflow system is the secondary air through blower into the vertical cooler, heat exchange hot air through the kiln hood into thelimestone rotary kiln with the material and involved in post-combustion from the kiln inlet into the preheater.

wet process rotary kiln inside movement principle: the combustion of pulverized coal injection device in thewet process rotary kiln head will produce a lot of heat, the heat transferred to the material in the way of flam eradiation, kiln brick conduction. The materials depend on the scroll of the rotary kiln and its slope to the forward movement. In industrial production, the rotary kiln machine is a cylindrical device with a certain slope, the slope of 2.5-3%, it is by means of the rotary kiln machine rolling materials to promote mixing in the kiln, so that the material contact with each other and mixed in together and then react. Raw material in the kiln during exercise, the movement of raw materials is cyclical changes, and some buried material layer inside the rotary kiln machine with the upward movement, while others are attached to the material layer on the surface and then landed down, but only in the raw material particles along the surface layer of the landing, it will move forward along the direction of rotary kiln.
