2.Sand lime brick plant introduction


Sand Lime Bricks (SLB):   Sand lime bricks are manufactured by mixing sand, fly ash and lime in desired proportion that may be followed by chemical accelerator during wet mixing.


This mixture is moulded under pressure.  The green bricks can be air cured for 24-48 hours and then steam cured in autoclave at desired pressure and temperature.


The green bricks may be steam / hot water cured at atmospheric pressure also.  In presence of moisture, fly ash reacts with lime at ordinary temperature and forms a compound possessing cementitious properties.

After reactions between lime and fly ash, calcium silicate hydrates are produced which are responsible for the high strength of the compound. Bricks made by mixing lime and fly ash are,


therefore, chemically bonded bricks.


3.Sand lime brick advantages


These bricks are suitable for use in masonry just like common burnt clay bricks.


These bricks have the following advantages over the clay bricks:


1. Possess adequate crushing strength as a load-bearing 

2. Have cement colour in appearance, are uniform in shape and smooth in finish and require no plastering for building work.

4.Sand lime brick machine working process


1.Raw materials sand,lime,fly ash are  loaded into three bin batching machine.If lime is in stone shape,it will be crushed into powder and stocked in lime silo.Three raw materials will be dosed and mixed in the bin under the batching machine.


2.The dosed material will be transported into mixer through belt conveyor.


3.After mixing,the mixed raw material will be stocked in silo for digestion thorugh bucket will last around 2hrs


4.The digested raw material will come into wheel mill and be grinded into powder.


5.The powder material will come into host machine mould area,be pressed into block shape.The common block shape is 240mm × 115mm × 53mm , : 240mm × 115mm × 90mm (or 115mm ) 240mm × 1 90 mm × 90 mm (or115mm )


6.The automatic stacker will stack the block and transport to the steam trolley.


7.The block will be steamed 8hrs in autoclave.After that,the whole production line is finished
