Vertical preheater

product description

  • The material is introduced into the preheater body from the silo on the top of the preheater through the discharge chute. At the same time, the high temperature flue gas introduced by the rotary kiln preheats the material to above 800 ° C, so that the limestone is pre-decomposed or partially decomposed, and then the hydraulic The push rod is pushed into the tail of the rotary kiln in turn, and after the high temperature calcination of the rotary kiln, it is unloaded into the single cylinder cooler to cool the material. The vertical preheater system is mainly composed of six parts. 1. Upper feeding system: It mainly includes upper silo and lower pipe. 2. Preheater body: It consists of preheating chamber, suspension device and refractory brick lining (this item does not belong to the scope of equipment design and manufacture). 3. Pushing device: It mainly includes pusher, frame and connecting rod. Each hydraulic pusher can push the material sequentially according to the automatic control program. 4.Hydraulic system: It mainly includes fuel tank, oil pump, motor, solenoid valve, hydraulic oil pipe, etc. Its main role is to control the pushing device and complete the pushing operation. 5. Lower feeding chamber: It mainly includes the slide tube, the main body of the feeding chamber and the feeding nozzle. Its main function is to introduce the preheated material into the rotary kiln for calcination. 6 frame: It mainly includes columns, ring beams, etc., whose main function is to carry the superstructure of the preheater.
