WHATIS AAC?
TheAAC production process includesraw material preparation, batching and mixing, pouring, precuring, cutting, autoclaving, and packing.WMachinery for Food, Beverage & Cereal ith decades of experience in serving the AAC blocks production machinery industry, we can supply customers with quality AAC block production lines with capacity ranging from 80,000m3to 400,000m3per year.Chart 1 the parameter of the processesProcessesParameterMixing period5-6 minutesPouring slurrytemperature40-45ºCCake cuHome Hardware ring time2.5-3.0hCake curing temperature45~55ºCCake strength after curing0.15~0.18MPaAutoclaved curing systemBefore-after autoclave0.5hVacuumize0.5h(0~-0.06MPa)Listing pressure1.5h(-0.06~1.3MPa)Constant pressure8h(1.3MPa)Releasing pressure1.5h(1.3~0MPa)total12hRAW MATERIALS
Siliceous materials : Sand / Fly ash / Tailings containing silicon / Ceramic waste
Calcareous material:Lime block + cement + gypsum
Others:Aluminum powder paste
THE ADVANTAGES OF AAC:1. Low density : Can be 325kg /m32. Good thermal insulating properties3. Cost few time to build, saving time4. Easy to operate , saving labor cost5. Good performance of preventing fire 6. Good sound-insulation properties7. Durable , anti-seismic , recyclable
CUTTING SYSTEM
Special cutting design : All the steel wire columns are fixed on two main oblique beams of cutting machine and each pair of the columns is used to fix only one steelwire , soHeating, Refrigeration & Temperature Control that the horizontal cutting machine can avoid the settlement cracks problem in thin block and panel cutting , and achieve the minimum horizontal cutting thickness of 50mm block out of a whole mould.The integral swing frame of the vertical cutting machinecan ensure the side platereplacement , the cutting action can be synchronized with ferry replacement. With automatic detection system . the broken wire can be timely detected.
PACKINGSYSTEM
Automatic packing system can realize the automatic rotation stacking and splicing of blocks andrealize the packing functionwith pallet or non-pallet. The stacking specification can realize 1.2mx0.6m1.2mx1m 1.2mx12m1mx0.6m multiple stacking , and the height of the stacking can be 1.2m,1.5m , 1.8m and 2.4m.
AAC FINAL PRODUCTS1. Product classification
Product classification is according to national standards GB/T 11968-2006AAC block, also can be according to user's requirements to produce product with special specifications size.

2. The block is classified by compressive strength and volume density.
Strength level: A1.0, A2.0, A2.5, A3.5, A5.0, A7.5, A10.
Dry density level: B03, B04, B05, B06, B07, B08.3. Block level
The block is divided into high-class(A), first-class(B), qualified product (C) according to the size variation, appearance quality, dry density, compression strength & frost-resistance.
