Concrete machine manufacturers for AAC / ALC Lightweight Concrete


Product Description



Brief introduce of concrete autoclave machine

Concrete autoclave machine is also called still kettle,a large,heavy pressure container which is widely used in aerated concrete block, concrete pipe pile, lime-sand brick, fly ash brick, microporous calcium silicate board, insulation asbestos board, high-strength gypsum building materials.

Generally after the process of curing(in fact it is Cao-Si02- H2O water thermal chemical reactions that take place within the kettle) products get the ultimate strength,it is the desired effect of increased service life.It is also suitable for rubber and wood drying and anti-corrosion,etc.


Maintenance and care of concrete autoclave machine

1.Clean the water and slag at the kettle bottom once a day,clean up the decontamination tank at fixed period to make the proper drainage of hydrophobic device.
2.Keep the lower clean for movable support, make the bearing get free expansion.
3.Keep each safety accessories working normally.
4.Keep the lubrication system for reducer in good state.
5.Rubber seals should be added lubricating oil,and the oil need to be clean for good seal.
6.Don't let any weight strike autoclave lid and body and produce mechanical damage, there is no chain, steel rope friction, such as drawing a pot cover.
7.All transmission parts and exposed bolt, nut need lubricating oil.
8.Exposed surface keeps intact,once discover paint falls off or blown down just go to fill paint.

So care your concrete autoclave machine,otherwise it will influence your AAC&ALC block production line deeply.


Key inspection area of concrete autoclave machine
1. pressure, temperature indicating record if is normal;Kettle lid closed must be in normal condition;Safety interlock is valid.
2. barrel, kettle cover, kettle end flange, valve, pipe parts for leaks of crack, bulge deformation, such as abnormal phenomenon.
3.discharge condensate device working condition;Cylinder bearing have wandering;Whether the kettle on both ends is flexible.


Manufacturing technique for AAC / ALC Lightweight Concrete
The device can take different process according to the category of raw materials, quality and technology characteristics of main equipment and so on.But in general, grind the fly ash or silica sand and water into slurry, adding powdered lime, cement, gypsum and foaming agent, after agitating,then inject into mold frame, quiet foaming and curing, cutting into various specifications of blocks or plates, taken into autoclaved kettle by steam car, formed into porous lightweight aerated concrete products under high temperature and saturated steam curing.




The advantages of AAC / ALC Lightweight Concrete

1.Light weight
Normal weight is 500~700kg/m3,only the equivalent of 1/5~1/4 of clay brick,1/5 of normal concrete brick.The weight reduce above 40% than the ordinary brick concrete structure building.
2.Perfect performance of heat preservation and heat insulation
The coefficient of thermal conductivity of aerated concrete is 1/6 of the normal concrete, heat insulation performance is better than the clay brick wall of 240 mm thick greatly.
3.Earthquake resistance
AAC block is light,the whole performance shows well,low inertia,so earthquake resistance is strong.
4.Excellent processing
AAC block can be sawed,planed,nailed,milled,drilled,etc,brings a lot of convenience and flexibility to the construction.
5.High-temperature resistance
When temperature is below 600 ℃, there is a slight growth for the compression strength,around 600℃, it is close to room temperature compression strength, fireproof performance reach the national fire protection standards.
6.Good sound insulation performance
The inner structure of AAC block is like bread,there are a large amount of air holes,so it has sound insulation,however general building material does not have.
AAC block can be produced according to the local material.It could be sand,coal ash,cement,etc.Can recycling, is better for the environment, the real trash to treasure.



Annual Capacity Estimation for AAC / ALC Lightweight Concrete

Here we take an example for annual capacity of 50,000 cubic meters:
1.Each car can load two pieces of green body,each body is 2.88 cubic meters,AAC block autoclave of 21 meters long could put five cars,so it is 2.88*2*5=28.8(CBM)
2.Adding aerated steam need about one and a half hours,curing time is 2 hours,releasing needs an hour and a half.
3.If three shifts a day can produce AAC block of 3 times.
4.The output in a year for each autoclave is 28.8*3*30*10=25,920(CBM),so it needs 2 sets for 21 meters long autoclave.But generally choosing 3 sets for actual selection.
5.According to the different parameters and other needs,100,000 cubic meters need 4 sets autoclave of 26 meters long,150,000 cubic meters need 5 sets of 30 meters long.

6.About the diameter:below 200,000 cubic meters choosing 2 meters,however exceed it choosing 2.85 meters,2.5 meters for standard block.


Process for concrete autoclave machine

Security architecture for concrete autoclave machine

1.Autoclave is steel-made horizontal tube-type device. The lid is made by pressing the whole steel plate Q345R (16MnR). The lid flange and body flange are made by forging the whole steel plate (model Q345R (16MnR)). The welding of pressure parts is heat-treated and go through strict non-destructive testing as the relevant standards required.
2.By hand speed reducer for opening and closing, the door of autoclave is mobile shutter structure.Also can adopt electric, pneumatic, hydraulic hoist according to the user's requirement.Equipped with perfect safe interlock protection device to avoid the wrong operation maximumly, ensure the safe operation and safe production of workers.
3.There are two opening ways which is top door and side door.The way of side open adopts the open structure of rotating arm type. Rotating flexibly, low operation, simple and convenient.The way of top door uses the lever, the lower lever and kettle door connect together, the upper is equipped with counterweight device, it is portable, small footprint for kettle side.
4.The sealing of the door uses imported rubber seals from professional manufacturers. Simple installation, good seal and long service life. The supports could be three kinds as different parts required: fixed support, mobile support and end dedicated support.
5.The autoclave has necessary valves and meters such as safety valve, pressure gauge, temperature measurement devices, intake valve, exhaust valve, sealing ball valve and hydrophobic valve. It also has decontamination tank for users to choose.
