Amulite Automatic AAC Block Production Line
What Is AAC Block?
The Concept Of AAC Block:AAC Block Is Based On Siliceous Materials(Sand,Fly Ash,Silica-Containing Materials Etc),And Calcareous Materials(Lime,Cement) As
The Main Raw Materials,Mixed With Air-Entraining Agents(Aluminum Powder),After The Process Raw Materials Batching,Slurry Mixing,Pouring,Pre-Curing,Cutting,Autoclave ,Curing Process And Package To Produce Out AAC Blocks Finished Products;It Is Called Aerated Concrete Because It Contains A Large Number Of Uniform And Small Pores After It Is Aerated.
What Is The Process To Produce AAC Block Products?
1) :All Raw Materials Metering And Mixed Slurry;
2) :Slurry Enter Into Pouring System,After Mixing Then Pouring Into Mold Box;
3) :Inside Mold Box(Panel Reinforcement),After A Certain Temperature And Pre-Curing Time;
4) :After The Wet Panel Reaches A Certain Hardness,The Mold Box And Panels Will Be Hoisted To The Cutting Machine By The Turnover Crane,And The Turnover Crane Completes The Following Function:
5) : A :Is To Turn The Mold Box 90 Degree In The Air,(One Side Of The Mold Box Becomes The Support Trolley Plate For The Wet Panel Body Until Autoclave Process Finished),
6) :B :Is To Hoist To The Trolley Or The Cutting Support Frame To Completely Open The Mold;C:The Took Off Mold Frame And The Return Autoclave Side Plate Are Recombined To Form A Mold Box After Cleaning,Spray Oil And Re-Pouring ;
7) :And The Wet Panel Body Is Cut In Six Steps On The Cutting Machine: 1:First Cuts Both Sides Of The Panel Body Vertically;2:Then Cuts Longitudinally And Horizontally;
8) :Finally Cuts Horizontally Horizontal Or Knife Cutting;
9) :The Cut Panel Body Is Hoisted From The Semi-Finished Product Crane Together With The Bottom Plate To The Autoclave Trolley;
10):Then Grouped Into The Autoclave For High Temperature And High Pressure Curing;
11):After Well Autoclave Curing,The Trolley Will Be Took Out And Leave The Autoclave ;
12):The Finished Products Are Stacked Or Loaded On The Truck By The Finished Product Hosting Crane,Packaged Well;
13):The Autoclave Curing Side Plate Are Returned ;
Production Process
1):Storage And Supply Of Raw Materials For AAC Block
Raw Materials Are Transported Into The Factory By Automobiles,And Fly(Sand,Stone Powder) Is Concentrated In The Raw Materials Yard,And When Used,It Is Conveyed Into The Hopper.Bagged Cement Or Bulk Cement Is Stored In The Cement Warehouse.When In Use,It Is Loaded And Transported Into The Hopper.Chemicals,Aluminum Powder Etc Are Placed In The Chemical Storage And Aluminum Powder Storage,Respectively,And Convey To The Production Workshop When Used.
2) :Processing Of Raw Materials For AAC Blocks
Fly Ash(Or Sand,Stone Powder) Is Sent To The Ball Mill Through Electromagnetic Vibrating Feeder And Belt Conveyor,And The Ground Fly Ash(Or Sand,Stone Powder) Is Sent To The Slurry Tank For Storage By The Fly Ash Pump.
The Lime Is Sent To The Jaw Crusher By The Electromagnetic Vibrating Feeder And The Belt Conveyor For Crushing.The Crushed Lime Is Conveyed To Lime Storage Tank By The Bucket Elevator,And Then Sent To The Ball Mill By The Screw Conveyor.The Screw Conveyor And Bucket Elevator Are Fed Into The Powder Batching Tank.After The Chemicals Are Manually Measured In A Certain Proportion,A Solution Of A Certain Concentration Is Made And Sent To The Storage Tank For Storage.
The Aluminum Powder Is Conveyed From The Aluminum Powder Warehouse To
The Production Workshop,And Is Lifted To The Second Floor Of The Batching Building With An Electric Hoist.Pour Into The Mixer To Add Water Quantitatively,And Stir It Into An Aluminum Powder Suspension.
3. Slurry Mixing,And Pouring Of AAC Blocks;
Lime And Cement Are Sequentially Sent To The Automatic Weighing Scale By The Screw Conveyor Under The Powder Batching Tank For Cumulative Measurement.There Is A Screw Conveyor Under The Scale To Evenly Add The Materials Into The Pouring Mixer.
Fly Ash(Or Sand,Stone Powder) And Waste Slurry Are Put Into The Measuring Cylinder For Measurement.After Various Materials Are Measured,The Mold Is In Place,And The Slurry Can Be Stirred.The Slurry Should Meet The Process Requirements(Approximately 45 ºC ) Before Pouring.If The Temperature Is Not Enough,Autoclave Heating Can Be Carried Out In The Slurry Metering Tank,And The Aluminum Powder Suspension Can Be Added 0.5-1 Minute Before The Materials Poured;
4. AAC Block Pre-Curing And Cutting
After Pouring,The Mold Box Is Pushed Into The Initial Curing Room By A Conveyor Chain For Gasification And Initial Setting.The Room Temperature Is 50~70ºC,And The Initial Curing Time Is 1.5-2Hours(According To The Favorable Geographical Conditions,This Process Can Be Eliminated).Use A Negative Pressure Hoist To Hoist The Mold Frame And The Wet Block Body Onto The Cutting Table Where The Bottom Plate Of The Autoclave Trolley Is Placed In Advance.Take Off The Mold Frame.The Cutting Machine Cross-Cuts,Longitudinally Cuts,And MillsThe Wet Block. The Mold Frame Is Hoisted Back To The Mold Truck For Clean And Degreasing,And Then Lifted To The Mold Truck For The Next Casting.The Cut Block Body And The Bottom Plate Of The Autoclave Are Hoisted On The Autoclave Trolley With A Crane And Placed On Two Floors.There Are Four Supports Between The Floors,And Several Autoclave Trolley Are Grouped Together. The Waste Materials At The Edges And Corners Of The Wet Block Body Produced During Cutting Is Sent To The Waste Slurry Agitator Next To The Cutting Machine By A Screw Conveyor,And Water Is Added To Make A Waste Slurry For Use In Batching.
5. Autoclaved AAC Block And Finished Product.
After The Body Is Assembled On The Parking Line In Front Of The Autoclave,Open The Autoclave Door That Is Going Out Of The Autoclave,First Pull Out The Finished Autoclave Trolley In The Autoclave With A Hoist,And Then Pull The Autoclave Trolley To Be Autoclaved Into The Autoclave With A Hoist The Autoclave Is Maintained.The Finished Products On The Autoclave Trolley Are Hoisted To The Finished Product Warehouse By A Bridge Crane,And Then Transported To The Finished Products Yard By A Forklift Truck.The Empty Autoclave Trolley And The Bottom Plate Of The Autoclave Running Are Hoisted Back To The Carriage Return Line,And The Stacker Is Pulled Back By A Hoist After Cleaning.Go To The Next Cycle.
