  Product Description AAC Block & Panel Production Line                                                                                                                           What is AAC ?                                                                                                                                                                         AAC is the abbreviation of Autoclaved aerated concrete,It is a new type of light weight , thermal insulation building material .The raw material are siliceous materials (such as fly ash, sand) and calcareous materials (lime and cement) ,made by batching, pouring, expansion, cutting, curing and other processes.1.Sand is widely used siliceous material in aerated concrete industry . The main function of sand is to provide SiO2.2.The role of fly ash in AAC is also to provide SiO2.And the Al2O3 in fly ash can give large effect during static stop after the casting process .3.Lime is the main calcareous material in the production process. Its main function is to provide calcium oxide, so that it can react with SiO2 and Al2O3 in the siliceous material under hydrothermal conditions to form calcium silicate hydrate, so that the product can gain strength.Finely ground quicklime is used in the production process.4.Cement is a hydraulic cementitious material, Portland cement is suitable for AAC.Parameter of the processesProcessesParameterMixing period5-6 minutesPouring slurry temperature40-45ºCCake curing time2.5-3.0hCake curing temperature45~55ºCCake strength after curing0.15~0.18MPaAutoclaved curing system before-after autoclave0.5hVacuumize0.5h(0~-0.06MPa)Listing pressure1.5h(-0.06~1.3MPa)Constant pressure8h(1.3MPa)Releasing pressure1.5h(1.3~0MPa)total12h Production Process IntroductionGas block wall panel pictures and photos                                                                                                                 The production process includes raw material preparation, batching pouring, static stop curing, cutting, autoclaving curing, , exiting from the kettle and packing . Raw Material Preparation 1. Raw materials need to be ground before being processed. In order to meet the fineness requirements of the feed, block materials such as quicklime and natural gypsum need to be crushed.2.Grinding can give full play to the activity of the material;The ground slurry has better water retention and higher viscosity due to the dissolution of some components , which can make the slurry have proper consistency and liquidity Material Batching and Pouring  1.Measure various raw materials, adjust the temperature and concentration, and feed materials to the mixing equipment in sequence according to the process requirements 2. The pouring process is one of the unique processes that distinguish aerated concrete from other concretes. The prepared raw materials are stirred to meet the specified time temperature and consistency requirements to obtain slurry, then pour into the mold.3.Pouring and batching can be controlled separately or centrally, and different degrees of automation can be realizedStatic Maintenance1.The poured mold is pushed into the resting room with a conveyor chain for initial gas generation and initial setting. The room temperature is 50-70°C, and the time is 1.5-2 hours.2.The resting process is mainly to promote the slurry to continue to complete the hardening process, so that the embryo body reaches a certain hardness for cutting Cutting  The cutting process is to divide and shape the AAC body to meet the appearance and size requirements. The cutting process reflects the characteristics of air-entrained concrete, which is convenient for large-volume molding, flexible and diverse in shape and size, and large-scale mechanized productionAutoclaving CuringThe autoclave curing process is to perform high-pressure steam curing on the cut aerated concrete body, and complete the hydrothermal reaction of CaO-SiO2-H2O in the kettle Packing  This is the last process of production, including pull out the finished products form kettle, lifting, inspection, packaging and cleaning and oiling of the bottom plate of the trolleySpecification                                                                                                                                                                Cutting Machine GroupMoldSomersault demoulding machineGas block Hoist: hoist block mould and groupingGas block AutoclaveGas Slurry Pouring MixerPackaging & Shipping                                                                                                                                        Our Factory   office buildingOur office building provides our staff with a comfortable working environment,thus we can keep improving our AAC machines and related service with higher productivity.
