Five members all have serviced for the German YTong more than
20 years.Make the Dongyue technology research and development capabilities in the world's advanced level in the field of AAC.

1.Introduction of aerated block equipment production line dongyue machinery group :
Areated concrete block (light block ) 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:600x200x100,80x80x180,240x115x53,600x200x125)
Areated concrete common conception Common concrete density is usually 1600-2400kg/m3,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%.
2.Comman sense of aerated block equipment production line dongyue machinery group :
1.Light weight ,Areated concrete density is usually 400-700kg/m3,(according the market in produce ),same as 1/3 of clay block and 1/5 common concrete.So use the Light block 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.
Have many kinds material,have lowest waste
3.Main Material:Coal ash sand waste mine material coal stonestone dust and other silicon materials.

4.AAC Brick Machine Line, Light Weight Brick Machine, Aerated Concrete Brick Machine Advantages
1) light weight
Autoclave Aerated Concrete Block density is usually 400-700kg/m3, (according the market in produce ), same as 1/3 of clay brick and 1/5 common concrete.
2) keeping temperature
Autoclave aerated concrete block 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.
