AAC block production line(DONGYUE) detail introduce:

Our Foamed concrete light weight(AAC:Aerated Autoclaved Concrete) block machine absorbed world advanced technology and could meet different client's requirement. Our AAC production line is famous for its excellent performance, high efficiency, and lower in energy consumption. Since putting into the market, good economic profits and social benefits have been achieved.

1.AAC block production line Introduction

Areated concrete brick (light brick ) is the light and porous buidling material. It has light

keeping temperature cant burn and other advantages.it can be made into many kinds of bricks(for

example:600×200×100,80×80×180,240×115×53,600×200×125),they could be used industry building and common building.they are more and more popular in the world.in the future,they will replace the Clay brick completely.2.Aerated concrete common  conception

Common concrete density is usually 1600-2400kg/m,but Areated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain,main use silicon material (for example:coal ash,sand,stone dust

and others ),through making the material small for example sand,they can be used directly if has

enough degree of small (for example coal ash.Mixing  calcium material lime cement water to a

special slop,then add the aluminum dust and the additive.Make the aluminum dust and the special

slop have a Chemical reflect.then produce Hydrogen to make the concrete slop to expanding or

swell,foam.Next,put them into the curing room to concreting cutting steaming curing,last,there will

bacome the light brick,the porous rate is 70-80%.

3.AAC block production line Advantages     (1)light weight     Areated concrete density is usually 400-700kg/m3,(according the market in produce ),same as

1/3 of clay brick and  1/5 common concrete.So use the Light brick can reduce the weight of the

build more,and also reduce the  beam of roof and pillar press best.then you can see,it can save the

material and cost,it also fighting shaking.    (2) keeping temperature     It has many are porous,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as  1/4 or

1/5 of clay brick,so it is best  materials now in the world.There are many kinds material,have

lowest waste.    (3)Main Material:coal ash sand waste mine material coal stonestone dust and other silicon materials.
