The Features of Preheater: 
(1) The upper feeding system: Includes the upper hopper, the next material possession, the next feeding method and structure can guarantee to the pre-heater of the body feeding to achieve security when closed, so that the cold air from outside can not enter into the preheater, and feeding can make use of valve rod to achieve continuous or intermittent feeding. 

(2) Preheater body: It is to ensure that materials preheated to 900 degrees Celsius of the most important part, it is by the warm room, hanging devices and brick lining (which does not belong to the scope of design and manufacturing equipment) and other parts. That part of the structure of most of metal structures, part of the material according to the need to use a heat-resistant steel, heat-resistant steel to 1100 degrees Celsius in 1000 to work under high temperatures. In addition, the refractory bricks lining structure, novel design, sealing is good, can guarantee the material in pre-heater evenly and achieve pre-heating temperature 

(3) Pushing devices: Mainly pusher, framework, and connecting rods and other parts of pushers, using heat-resistant steel casting or welded together, can withstand high temperatures, using electronic control and hydraulic systems can be by putting the various hydraulic automatic control program to achieve sequential pushing. 

(4) The hydraulic system: Including tanks, pumps, motors, solenoid valves, hydraulic tubing, etc., its main role is to control the pusher device to push the completion of material movement. 

(5) Bottom feeding room: Mainly including slide tube, main feeding room, feeding slip mouth and so on, its main role is to import the materials after preheating. 

(6) Framework: Including columns and ring beam and so on, the main role is to support the upper part of the structure.
