After crushing, the lime & gypsum grains are stored in vertical silo, the granularity should be no more than 25mm. Then the grains are fed into ball mill by separate belt scale, and will be sent to granular cementation silo when granularity reaches 3500~4000cm2/g.   2. Mill the sand to slurry in wet ball mill and put the slurry into tank for storage.   3. Add the sand slurry, granular cementation materials & cement which are scaled as per proportion into the casting tank equipped with stirrer for mixing, a certain amount of steam should be entered into the stirrer for increasing the raw materials temperature to 40~45℃.   4. After mixing of 3~4min, open the discharger valve of aluminum powder, feeding into the tank, and continue mixing about 40 seconds, then pour the mixed slurry into mould for casting. The whole cycle is 6~8min.   5. Transport the casting cake with mould to curing zone for foaming and concreting, environment temperature is 40~45℃ and curing time is 90~150min; and then pull out them from the curing zone when the strength reach the lowest cutting strength.   6. Transport the mould with casting cake to cutting zone. A titling machine separates the cake from the mould and put the cake onto loading car after 90 degree overturning. After vertical cutting & cross cutting the cake turns into blocks (L ± 3mm ~ W ± 1.5mm ~ H ± 0.6mm), then the ground turning device turns 90 degree and place the blocks onto autoclave base plate.   7. The loading car transports the cakes into autoclave with temperature 190℃ and steam pressure 1.2MPa, autoclaving cycle is 12H. The tail steam of the autoclave will be recycled into other autoclaves and/or to curing zone by pipe for completely utilization.   8. After autoclaving, the blocks are put in different stacks, and the separate moulds are transported to mold cleaning zone for cleaning and continuously production.   9. The waste materials will be collected into a waste slurry tank, where mixed with fresh materials in a correct proportion for further production.       4.2 Technological data   Mixing cycle:                                                             6 ~ 7 minutes   Casting temperature:                                                 40 ~ 45℃   Curing time:                                                              2.5 ~ 3.0h   Environment temperature for curing:                           45 ~ 55℃   Autoclave loading /unloading:                                       0.5h   Vacuuming:                                                                0.5h (0 ~ -0.05MPa)   Pressure up:                                                              1.5h (0.06 ~ 1.2 MPa)   Constant pressure:                                                        7h (1.2 MPa)   Pressure down:                                                         1.5 h (1.2 ~ 0MPa)   Total:                                                                        11h Lower Price High Quality AAC Block Production Line :workingsite AAC Block Cutting Machine/AAC Block Making Machine Pro AAC Block Panel Pouring Mixer/AAC Block Production Line Process Typical stages involved in the AAC panel production process include raw material preparation, batching and mixing, pouring, pre-curing, cutting, autoclaving, and packing. Lower Price High Quality AAC Block Production Line : overview                                                             Batching  Pouring Mixer The pouring mixer is a key element on the AAC block production line. It keeps the concrete from hardening by constantly tumbling the mixture around. In the mixer, ingredients of desired proportion are blended and then poured into the mould for pre-curing. Lower Price High Quality AAC Block Production Line  :pouring mixer                                                    Pre-curing and Cutting Mould The mould is a vessel into which concrete slurry is poured. In the mould, the slurry stiffens to form the green cake. The green care rises due to the evolution of hydrogen gas from the reaction between aluminum powder and rest of concrete slurry. The process is termed as pre-setting. Lower Price High Quality AAC Block Production Line :mould   Mould Turning Machine The mould turning machine is mainly used to turn the pre-set concrete through 90 degree so that the mould can be easily removed from the concrete to facilitate cutting. This process leaves two side plates of the mould on the concrete. The purpose of side plates is to support the preset concrete and keep it from collapsing. After de-mould, the incomplete mould combines with two new side plates to form a complete one again, which readily accepts the next concrete pouring.   Lower Price High Quality AAC Block Production Line :mould turning machine   Cutting Machine The cutting machine is used to precisely cut all the six sides of concrete cakes to various required dimensions. It is mainly made up of transfer car, vertical cutter, cross cutter, and car exchange device. Lower Price High Quality AAC Block Production Line  :vertical cutting machine Tilting Table for Semi-product As the cutting is completed, the green cake is tilted back by 90° so that it sits on its wide, lengthwise side. At this point, a scraper is used to remove the bottom waste as well as clean the bed. Wastes that are washed off into the pit will be recycled, which results in cost savings. All these motions are driven by hydraulic cylinder and controlled via proportioning valves to ensure stability. The big transfer car, small transfer car, tilting bed, and scraper are the major parts that make up the whole tilting system. Lower Price High Quality AAC Block Production Line :tilting table for semi-product   Stacker for Semi-product The stacking machine is used to transfer the concrete panel together with the bottom plate of the mould to the de-moulding crane and the autoclaving car. It also returns the side plates of mould to the roller conveyor. Lower Price High Quality AAC Block Production Line :stacker for semi-product                                            Curing and Final Product Handling Curing Car The curing car, also known as autoclaving car, is an integral part of the autoclaved aerated concrete production line. It carries the semi-finished concrete panels (which are seated on the bottom plate of the mold) to the autoclave.   Lower Price High Quality AAC Block Production Line :curing car   Ferry Car The ferry car is a kind of material handling equipment that travels across the line of AAC production. Thanks to this transfer trolley, the mould-carrying car and the cake-filled autoclaving car can run on each other’s rails.
Chain Conveyor In the chain drive system, the sprocket receives power from the motor and transmits it via the chain to the driven sprocket installed on the tow-car. The tow-car then pulls other equipment back and forth along the rail, with the help of pushing and towing unit. Main parts of the chain conveyor include the transmission unit, towing unit (tow-car), and rear wheels.   Autoclave Autoclave is a large steam equipment which can be used in steaming sand aac block,flyash aac block and aac brick/panel. Lower Price High Quality AAC Block Production Line :Autoclave   Separator After autoclaving, the piled-up concrete panels need to be separated along the cuts, one layer from the next. The purpose of separation is to keep each individual AAC panel from sticking to the adjacent ones. The separating operation is carried out by the separator, which is made up of the separating device and lifting device. The lifting motion of the separator is driven by a hydraulic power unit. Proportioning valves are used to control the hydraulic unit to ensure operating stability.   Lower Price High Quality AAC Block Production Line :separator   Clamping Machine The clamping machine takes hold of each individual AAC block/panel and carries it to the packing line.   Lower Price High Quality AAC Block Production Line :clamping machine   Packing Line The packing line is designed for improved efficiency and reduced labor cost. A number of pallets are arranged along the packing line. Each individual AAC panel is lifted by the crane and put down on the pallet. Once the packing operation is started, the pallet together with the AAC panel moves along the packing line. Lower Price High Quality AAC Block Production Line :packing line   Annual Output Table
