AAC Block Automatic Concrete Machine Holland Brick MachineAAC Block
Automatic Concrete Machine Holland Brick Machine IntroductionHongfa
factory with 80 production line plants abroad AAC (Autoclaved
aerated concrete) block Main raw materials of AAC are siliceous
material (sand, fly ash, and Silicon tailings) and Calcium
materials (lime and cement) mixed with a foaming agent (aluminum
powder).It is the product of light porous silicate through the
following processes: batching, mixing, pouring, hardening, cutting,
autoclaving and curing etc. Because of large amount of
well-distributed tiny pores after foaming, it is named autoclaved
aerated concrete. AAC Classification: In general, it can be
classified according to the types of raw materials, manufacturing
process and functions.Based on the shape of AAC products, it can be
divided into: AAC blocks and AAC panels. It is a revolutionary
material offering a unique combination of high durability and
strength, low weight, excellent heat insulation, fire resistant,
noise absorption, unprecedented buildability and superior
ecological green features. In China, AAC is one of the light wall
materials which was popularized and applied at the earliest and the
most widely. AAC Block Introduction AAC Block
Automatic Concrete Machine Holland Brick Machine raw materialAAC
block raw material required performance:Fly ash: A lot has
been said about this raw material in this Project Profile itself.
But this Raw material is freely available inThermal Power plants.
There are no taxes on this item whatsoever. Transportation charges
are only to be attended by theentrepreneur.Sand (65-70%): The core
raw material of AAC product; the main resource of silica-aluminum
components; correspond with JC409-91, the clay should less than
4%.Lime(12-20%): One of the main raw materials of fly ash AAC; the
main effect is to provide efficient calcium oxide with cooperation
of cement making calcium oxide react with SiO2, Al2O3 in hot water
then to produce calcium silicate hydrate. Therefore, lime is also
the main resource of strength. Effective calcium oxide of lime
should not less than 65%, over 80% is perfect and should accord
with JC/T621-1996.Cement(8-10%): This Project aims to utilize OPC
cement as main binder material. It will give faster strength to the
bricks,besides giving improved consistent quality. It also ensures
a better cost effectiveness for the same. Using OPC will be
astandardized practice. The other prime advantages of using OPC
(compared to other binders) is it's easy availability
locallythrough nationwide Retail Network of Cement
Companies.Gypsum(1-2%): Gypsum is the foaming regulator in AAC
which dispels quicklime and postpones slurry's densification.CaSO4
should be more than 70%.Aluminum Podwer(0.074%): It is the forming
agent type and recommendation for supply depend on raw materials
and mix formula:A lot has been said about this raw material in this
Project Profile itself. But this Raw material is freely available
in Thermal Power plants. There are no taxes on this item
whatsoever. Transportation charges are only to be attended by the
entrepreneur.Manufacturing Technique with AAC Block Automatic
Concrete Machine Holland Brick Machine Raw material
dealingPut the fly ash or sand into the ball mill to mill via the
conveyor belt, after milling, put the slurry into the slurry
storage tank by slurry pump. Batching, mixing and
pouring processThe lime, cement will convey by conveyor to the dry
powder measure scale to scale separately. The slurry convey by
slurry pump then to the automatic scale;the power and slurry put
into the mixer,pouring into the mould. Curing processAfter
slurry pouring into the mould, put the mould box into the curing
room with 50~70ºC. After 2-3 hours curing, the blocks become soft
solid and ready for cutting. Cutting processCutting size can
be adjusted flexibly, with 0 broken rate. Aerated
autoclaved processFinished product cutting using semi-product crane
carry to the front of autoclave grouped, hoisting machine or
dragger will drag steam trolley into autoclave to steam,it need
6-10 hours. Finished block dealing processAfter 6-10
hours, finished products come out of autoclave, with separting
machine to separate blocks layer by layer. Packing
processUsing finished block carry hanger clamp the finished product
to package line on wooden pallets,after package, then by forklift
transport the finished products to piled yard according to
specifications to stack.Packing&Shipping for AAC Block
