The cover block for column making machine manufacturer introduces the production process of aerated concrete
Aerated concrete is mainly made of siliceous and calcium materials, accompanied by aerating agent.
It is named because the aerated concrete contains air bubbles after it is initiated.
Aerated concrete is generally used in the production of non - bearing masonry.
Aerated concrete is usually produced by specific equipment, and the production process is as follows.
1. Raw materials for storage and feeding of aerated concrete blocks shall be transported into the factory by automobile. Fly ash (or sand and stone powder) shall be concentrated in the raw material field and shall be loaded into hopper for use
2. The raw material treatment of aerated concrete blocks fly ash (or sand, stone powder) is sent to ball mill by electromagnetic vibration feeder and belt conveyor, and the finely ground fly ash (or sand, stone powder) is sent to slurry tank for storage by fly ash pump.
Lime is sent to jaw crusher for crushing by electromagnetic vibration feeder and belt conveyor, and the crushed lime is sent to lime storage bin by bucket elevator, and then sent to ball mill by screw conveyor, and the ground material is sent to powder feeding bin by screw conveyor and bucket elevator.
After the chemical is measured artificially in a certain proportion, the solution of a certain concentration is prepared and sent to the storage tank for storage
3. Air block batching, stirring, pouring lime and cement are delivered to the automatic measuring scale by screw conveyer under the powder feeding bin for cumulative measurement. If there is screw conveyer under the weigher, the material can be evenly added into the pouring mixer.
Fly ash or sand, stone powder and waste slurry in the measuring cylinder measurement, measurement in a variety of material after mold already in place, can be slurry mixing, slurry before pouring should meet the process requirements (about 45 ℃), such as the temperature is not enough, can be in slurry tank steam heating, 0 before pouring material.
Add aluminum powder suspension for 5 ~ 1 min
4, at the beginning of aerated block cutting after casting mould with conveyor chain and the gas at the early push to raise the initial setting, room temperature is 50 ~ 70 ℃, in the early time of 1.
5-2 hours (this process can be avoided according to the favorable geographical conditions). After initial cultivation, the mold frame and blank body are hoisted together by the negative pressure spreader to the cutting table with the bottom plate of the kettle.
Remove the frame.
The cutting machine is to cut the billet horizontally, longitudinally, and mill the bread head. The frame crane returns to the mold truck to clean and remove oil manually, and then it is hoisted to the mold assembly on the mold truck for the next pouring. After the cutting, the blank body together with the bottom plate of the kettle is hoisted to the kettle truck for two layers, with four supports between the layers.
The billet body corner waste produced during the cutting process is sent to the waste pulp whipping machine beside the cutter by the screw conveyer
5. After the completion of marshalling on the parking line in front of the kettle, open the door of the autoclave to be discharged from the kettle, first pull the finished product car out of the kettle with the hoist, and then pull the autoclave into the autoclave for maintenance.
The finished products on the car are hoisted to the finished products warehouse by the bridge crane, and then transported to the finished products yard by the fork truck. The empty car and the bottom plate of the kettle are hoisted back to the carriage line, and the yard is pulled back to the yard by the hoist for the next cycle
As the production raw materials of aerated concrete are various, and the waste residue can be used synthetically to reduce the pollution of waste residue, it is of great help to the environment, and it is strongly supported by the national policy.
