aac plant: -20,000m3 to 300,000 m3 per year; -fully automatic; -Adopt pre-curing before steam curing; -BV and ISO;

Brief Process of aac plant:

 

Firstly dose and batch measured raw materials

Feed batched raw material into casting mixer to make slurryThrough thoroughly mixing, the ready slurry is poured into the mouldAfter pre-curing under a certain temperature and period, the block would reach a certain hardness prepared for cuttingTilting hoist would turn over 90 degree of mouldThen open the mould and separate it from the block, and take the block with side plate onto cutting cartThe blocks then be cut through the cutter firstly of two vertical sides of blockSecondly the horizontal cuttingFinally the vertical cutting

10.  After cutting, the block is hanged to curing cart with side plate by semi-finished product hoist.

11.  Grouping the cut blocks and put them into autoclave

12.  Hardening the blocks under certain temperature and pressure

13.  Take finished products out of autoclave

14.  The finished product is taken by finished product hoist to stock

15.  Packed for loading

16.  The side plate return back by side plate rail

17.  Side plate is organized together with empty mould

18.  Clean the mould and preparing for next pouring

 

Principle of aac plant

Tilting hoist turns the mould with the blank 90 degrees in the air, then demould the blank and put it on the cutting cart together with the side plate. The cutting car is powered by motor and

walk to stay, finish cuts vertically , mills the trough , level to cutting through vertical cutting device. The cutting cart continue walking under the central position of the crosscut device and stops, the crosscut device is started, crosscut shelf from top to bottom and the cross cut is finished. The cutting car walk to the semi-finished product hoist, and the semi-finished product hoist will take the cut block with the side plate onto the curing cart to the autoclave. The cutting cart return to the primitive position for next circulation.

 

 

Character of aac plant

 

The structure is simple and practical, easy to install and maintain.After tilting, the blank stand vertically with width 600mm and height 1200mm, which makes the cutting wire shorter and it is not easy to be broken and drifted. The cutting is more precise.As the blank stand vertically, the grooves on both sides of the blank can be milled at the same time when the blank is cut vertically, no groove processing device is needed.It is simple to operate, the cutting is finished in different positions and the cutting and running is controlled by the same device, therefore, operation is simplified and convenient.The wire is tensioned by cylinders, the tensile force is same for every cutting wire. This make the cutting quality(cutting precise and outer size) is more reliable and more easy to control. The advantages of the tension method by cylinder. 1) Cylinders are standard parts easily sourced from market. 2) The tension force by cylinder is same exactly no matter the error of the wire length. 3) The tension force is adjustable. 4) As the wire is replaced under zero pressure of the cylinder, it is easy to replace and install the wire and no breaking happen.

Quality Requirements of Raw Materials

 

1, fly ash Fly is the core of this product materials.2, cement is a major source of strength

3, Lime is another key role of strength in aac block production.

4, gypsum

5. Sand is the main basic material6, Aluminium powder paste (Aluminum powder paste) 

Main features of AAC block

1.Light and high strength2.Fine Insulation Material and heat preservation3.Excellent sound insulation.The double rendering walls can reach up to 46db.4. fireproofing5.Last for long time6.Pollution free products7.Good frost resistance (safely free from being frozen8.Outstanding ability of preventing osmosis9.Fine waterproofness and inteneration10.Easily to be processed
