Production technology of Autoclaved Aerated Concrete (AAC)
1) Raw materials handling
Fly ash (or sand, rock flour) is transported into the ball mill through feeder and belt conveyor driven by electromagnetic vibration. After milled, it is sent to the pulp tanks for storage with fly ash pump
The lime is carried into the jaw crusher for crushing through feeder and belt conveyor driven by electromagnetic vibration., after crushed, it will hoisted to the lime storage bin with bucket elevator, and then sent to ball mill through screw conveyor, and the milled materials will be put into the batch bin through screw conveyor and bucket elevator. Chemicals are made into a certain concentration of solution according to a certain proportion after the artificial measurement, and sent into the storage tanks for storing
2) Raw material storage and feeding of Autoclaved Aerated Concrete (AAC)block
Raw materials are transported into the factory in the automobiles, fly ash (or sand, rock flour) is concentrated in raw material field, when using, packed and shipped to the hopper .Bagged cement or bulk cement is stored in cement silo, when using, packed and shipped to the hopper. Chemicals and aluminium powders are stored in chemical warehouse and aluminum warehouse, when using, respectively shipped to production workshop
3) batching, mixing, pouring
The lime, cement is transported to automatic quantitive scale for cummulative metering in turn by the screw conveyor under the batch bin. The screw conveyor can add materials uniformly into the pouring mixer.
Fly ash (or sand, rock flour) and waste pulp are put into measuring cylinder for measuring, when all kinds of materials are measured, and the mould already in place, then begin to mix the slurry, before pouring it should reach process requirements (about 40℃), if not enough temperature, make the steam heating in measuring tank. The materials are added into the aluminum suspension 0.5 ~ 1 minute before pouring.
4) primary curing and cutting
After pouring, the mould is pushed into the curing room for initial setting with the conveying chain, room temperature 50～70℃, curing time 1．5-2 hours(According to the geographical advantages, the process can be avoided).After primary curing, hang the mould frame and body together on the cutting table placed with kettle floor in advance by negative pressure sling, pull off the frame, and the cutting machine makes the crosscutting and lengthcutting of the body. The frame is hoisted to the mould carriage for artificial cleaning and oil removing, and then group the mould for the next pouring. The cut body along with the kettle floor is hoisted to kettle car and put into two layers with the crown wheel, between which there are four supports, and several kettles is made up into 1 group.
The waste materials generated from cutting are shipped to the slurry mixer beside the cutting machine through the screw conveyor, and made into waste slurry, by adding water, for the use of matching materials.
5) Autoclaved and finished product
After the body finishes the grouping on the stop line before the kettle, open the autoclave door, firstly pull out the finished kettle car with the hoist, and then pull the kettle car to be autoclaved into the autoclaved kettle for curing with the hoist. The finished products on the kettle car are hoisted to the finished-products storage with overhead crane, and then shipped to finished-products storage yard with the forklift. The empty kettle car and the kettle floor are hoisted back to the turn-around, after cleaned, pulled back to the parking yard with the hoist for the next use.
