9 Steam curing cycle time, come in and out autoclave about 0.5hour, steam curing cycle time about is 6 hours/1.6Mpa, total 6.5 hours.
10.Cement lime fly ash style aerated block raw material proportion
waiting for using.Sacks of cement and bulk cements stored in cement warehouse.Chemicals and aluminum powder
are separately kept in chemical warehouse and aluminum warehouse.When used,these raw materials are carried into
workshop respectively.Quick lime is sent by vibrating feeder and belt conveyor into jaw crushers to smash. Smashed
lime is sent into lime silo by bucket elevator and then is transported into ball mills by screw conveyor. Fined materials
are sent into proportion bin by screw conveyor and bucket elevator.Aluminum powder is lifted by a truss motor to
second layer of batch planta and empty into mixer.
2.Aerated block Dosing, Stirring and Casting
Ground lime and cement is measured by lime and cement measuring tank.
All the measuring and dosing is in the batching center, controlled by PLC automatic controlling computer, to make
sure of continuity and accuracy in the process of dosing.Materials slurry is transported by screw conveyor into
mixer ,together with aluminum powder. Slurry temperature should reach about 40° -This is technical requirements.
If the actual temperature doesn’t arrive 40°,vapor is used in the measuring tank to raise temperature.
3.Setting,curing and foaming.
Materials slurry in the mould is transported to the place for setting,curing and foaming by ferry push car .When it is
conveyed to precuring room, room temperature should range from 50 to 70°.This period lasts one hour and a
half to two hours(If materials take on geographical advantages,this precuring can be eliminated) , then the slurry
approach the cutting intensity, which we call green blank.
4,Cutting and organizing into groups
Sling takes green blank to the cutting board together with the mould and the side plates. Turning over sling turns the
blank with 90 degrees in the air. After demoulding, it conveys the blank to the cutting car. The cutting car driven by
the motor runs slowly through the vertical cutting device, and runs to the horizontal cross-cutting device after vertical
cutting is finished. When the cart is stopped at the middle place of the horizontal cross-cutting device,cross cutting
