Aerated Concrete Equipment

Aerated Concrete equipment introduction:

Aerated concrete product manufacturing is the pillar industry of construction field with almost 100 years' development abroad. It has been 40 years since our country introduced the technology. By 30 years' development, the aerated concrete process and equipment produced by our company has entered maturity stage. With advantages of low bulk density, high heat retaining property, good sound absorption effect, certain intensity and workability, and so on, aerated concrete brick is a kind of wall material that can replace traditional solid clay brick. There is abundant material source for making aerated concrete brick, especially flyash which will not only comprehensively utilize industrial waste and reduce environment pollution with no damage to farmland, but also bring favorable social benefit and ecnomic benefit.

Aerated Concrete Equipment

Aerated concrete production process description:

Process 1. Aerated concrete brick material storage and supply

Raw material is delivered to factory by truck. Flyash ( or sand , rock powder) is piled at raw material yard, and conveyed to hopper if necessary. Bagged cement or bulk cement is stored in cement silo, and conveyed to hopper if necessary. Chemicals, aluminium powder, etc. are put in chemical silo and aluminium silo, and conveyed to workshop if necessary.

Process 2. Aerated concrete brick material treatment

Flyash ( or sand, rock powder), via electromagnetic feeder and belt conveyor, enters ball mill and then the ground flyash ( or sand, rock powder) is delivered to slurry tank for preservation by flyash pump.

Limestone, via electromagnetic feeder and belt conveyor, enters jaw crusher for crushing. The crushed limestone is conveyed to limestone silo and then be delivered to ball mill by spiral conveyor. At last, the ground material enters powder batch bin via spiral conveyor and bucket elevator.

After manual measurement by certain proportion, chemical is made into solution with certain density, and put into reserve tank.

Aluminium powder conveyed to workshop from the silo is lifted to second floor by electric hoist and poured into mixer. Added with some water, the mixer will blend the aluminium powder into soliquoid.

Process 3. Aerated brick dosing, mixing and casting

Limestone and cement are orderly conveyed to automatic weight scaler by sprial conveyor under distributing tank for weighing. Sprial conveyor under the weight scaler will convey the material evenly to casting mixer.

Flyash ( or sand, rock powder) and slurry are weighed in measuring tank. After all materials are measured and moulds are all ready, it can take slurry mixing. Slurry temperature shall reach process requirement ( about 40^oC) before casting. If not, it can heat the measuring tank by steam, and add aluminium powder soliquoid 0.5-1 minute before slurry casting.

Process 4. Aerated brick cutting and primary maintenance

After casting, mould is conveyed to primary maintenance room for initial setting, with room temperature 50~70^oC, and maintenance period 1.5-2 hours ( it can skip this process by advantaged geological conditions). After primary maintenance, mould frame and clay body are hoisted to cutting table with kettle bottom plate by negative-pressure hanger. When mould frame is taken off, cutting machine begins to work on clay body like tranverse cutting, vertical cutting and face milling. Mould frame is hoisted to mould carriage for manual cleaning and oiling, and then hoisted to mould car for next casting. The cutted clay body with kettle bottom plate is hoisted to kettle car and lied in two layers. Between layers are 4 supports. Several kettle cars are composed as one group.

Edge scrap of clay body caused during cutting is conveyed to waste slurry mixer beside cutting machine by spiral conveyor. It can be made into waste slurry for next burdening use by adding water.

Process 5. Aerated brick autoclave and final product

When clay body is completely orgnized at stop line before kettle, open the autoclave gate that to be discharging, use windlass to pull the final product kettle car out, and pull the prepared kettle car to autoclave for maintenance. Final product in the kettle car is hoisted to final product storehouse by bridge crane, and then delivered to final product pile by forklift. Empty kettle car and kettle bottom plate are lifted to turn-around line, and pulled to skeletal for next circle by windlass.
