FLYASH AAC block PLANT EQUIPMENT

( light weight Capacity: from 50000 cubic meter to 300,000 cubic meters per year.)

Introduction of aac production line

    AAC Brick Production Line (light brick ) is the light and porous buidling material. It has light weight 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.

AAC Brick Production Line

     Common concrete density is usually 1600- 2400kg/m3,but AAC Machine are 550kg/m3-680kg/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%.
