Brief introduction:
After being machined on SUNITE machinery as a whole, the side plate is equipped with much SUNITE AAC BLOCK making machine/sand brick pressing machine/red brick making machines lifetime.
More stable structure and more scientific processing technic as well as the heaviest weight in China market ensure that SUNITE's side plate can be used for more than 10 years without deformation. Side plate assembled with mould as a vessel contains slurry and after being separated with mould by titling hoister, the side plate carries the block cake to cutting machine and into autoclave. All side plates can be recirculated and assembled with any mould.
Main Process Flow of AAC Production line/AAC block
1. Raw material: Store the fly-ash (tailings etc), lime and gypsum after milling to the needed fineness (200 mesh)
2. Mixing the fly-ash, cement, lime, gypsum and water in the pot after batching.
3. Promote the slurry temperature to 40-50 degree by steam, and mill with aluminum powder for 1min.
4. Pour the slurry into the mould, and still in the curing room for frothing in 2-2.5h.
5. Cut it in to needed size by the cutter after the slurry approach the cutting intensity, and place the block on the trolley.
6. Autoclaved curing after the trolley enter into the autoclave (SUNITE AAC BLOCK making machine/sand brick pressing machine/red brick making machines, rise the pressure, keep the pressure, reduce the pressure),keeping the constant pressure 1.2MPa. The whole process needs about 8 hours.
7. The products out of the autoclave are placed in a stack. We can recycle the scrap and the waste water from the whole production.
AAC BLOCK advantages:
1.Lightweight: Porosity achieve 70% to 85%, volume density is generally 500-900kg/m3, as 1/5 of general concrete brick,the 1/4of clay brick, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building,moreover,prolong building’s life.
2.Fireproof: Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 100 mm walls can reach to 4 hours fire resistance, 300mm thick up wall can reach to 9 hours fire resistance.
3.Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 100mm thick wall up to 41 db.
4.Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
5.Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
6.Anti-seismic: The same building structure, improve the two seismic than the brick level.
7.Green: Manufacturing, transportation, all use the process of non-pollution, to protect arable land, saving energy, is one kind of a green building material.
8.Durability: material strength is stable, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable even after ten years.
9.High workability: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
10.Economies: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
With honesty and trustworthiness,to all users!

The entire center feeding: Sand Making Machine Material falls the feed hopper, then enters the high-speed rotary sling wheel from center feeding hole, which is speeded immediately in the sling wheel. SUNITE AAC BLOCK making machine/sand brick pressing machine/red brick making machines The speed can reach several dozens times of the gravity acceleration. Then Sand making machine is thrown from the sling wheel. First, Sand Making Machine is crushed with other rebounded material fell freely from the sling wheel.

Then both of them are impacted to the material lining (rock-rock) or strike back block (rock-iron), rebounded and stroke to the Good of eddy cavity of Sand making machine in the inclined-up direction. Then SUNITE AAC BLOCK making machine/sand brick pressing machine/red brick making machines moves along deflection-down, and forms a continuous material curtain with the material from the impellers passage. Just like this, the material is stroke, rubbed, crushed twice or more, then is discharged from the down discharging hole. There is little loss for medium-sized and fine sand and stone powder. Sand Making Machine The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction. There are no other wear parts except the screen mesh. SUNITE AAC BLOCK making machine/sand brick pressing machine/red brick making machines has longer service life and little maintenance chance.
