4.Storage and processing of the raw material
Full-automatic AAC production line Aerated automated lightweight aac plant Foam block cutting machinery aac cutting machinery
A.Sand (Fly ash)
The sand is bought according to requirements. When transported to the factory, it should be stored by classification. After
sampling analysis, sand of different quality is allocated . Then it will be transported by the conveyor, grinding head hopper, and
the electromagnetic vibrating feeder into ball milling machine to make into slurry. It is automatic feeding controlled by the control system and uses the slurry densitometer to monitor the density of the slurry. Feedback control the speed of inflow of sand and water of the grinding machine to achieve the automatically control of slurry.
The grinded sand slurry (fly ash) should be mixed with the industry waste slurry to make up the required density, and stored in the silo of 50 m3. When used, it is conveyed to the slurry silo of the batching building for spare by slurry pump.
B. Lime
The block lime is transported into the factory by dump trucks and unloaded into the lime store. Then it is broken by the jaw crusher and stored in the lime grinding head store through bucket elevator. When grinding, the lime is transported into ball mill by the feeding machine on the base of the store. The grinded lime is sent into the bucket elevator by the screw conveyor at the exit of the ball mill. Then it is sent into the lime powder store for spare by the bucket elevator. The silo should be set up an alarm whether it full or empty.
C. Gypsum
Using the gypsum (block gypsum CaSO4·2H2O), after the sampling analysis of gypsum and lime, according to designed proportion, feeding the material into lime treading system to crush and grind. Actual operation according to the procedure of implementation; When the industrial waste gypsum is used (generally powdery gypsum, CaSO4·2H2O), it should be transport into sand treading system to grind.
D. Cement
Cement is transported by bulk cement truck into factory. It is transported into cement silo using air conveyor device of the truck directly. The silo should set up an alarm whether it is full or empty.
E.Aluminum paste
Packaged aluminum paste is bought and placed in aluminum storehouse. When used, it is transported to storied building by electric hoist crane. After measured, it is put into aluminum measuring mixer for usage. When used, it is measured by the aluminum scale attached to the mixer. Then it is put into the pour mixer. The process of aluminum suspension will be made after the parameters by automatic control system completed.
F. Admixtures
Admixtures are purchased from professional manufacturer. Based on the ingredients, they are stored in bags. They are feed by labour. When necessary, it is can be stalled the automatic control agitation systems for the realization of self-control.
G.Scrap, waste slurry
The scrap cut from the cutting line and the waste produced when overturn, fall down on the bottom of the chute, then are pushed to the base of the cutting machine. Finally after pulped to a certain concentration, it was transported to the waste slurry storage tank by the vertical mud pump and mixed with sands according to the proportion and sent to the pulp storage tanks again. Waste pulp concentration is controlled by the density spectrometer. When the density is low, the control system make the waste slurry cycle in the waste slurry pool. And when the density arrives at the standard, the waste slurry is transported to the waste slurry tank.

1,Agglomerate lime is firstly crushed by jaw crusher, and then the granule lime is milled by energy-saving mill.
2,Mixing the fine grinding sands and the waste slurry for the slurry can improves effectively the stability of the slurry.
3,The slurry and powder are weighed by electronic measurement. The measurement and pouring of batching plant are controlled by central control room.
4,The pouring method adopts fixed point pouring.
5,It chooses the JQF 6.0 step by step cutting machine (Made in China). The maximum cutting size is 6.0×1.2×0.6m and the capacity of the cutting machine is about 400,000 m3 per year. The cutting precision reaches the China advanced level among the same size.
6,The autoclave kettle adopts 2 upward-acting doors to decrease the time of the brick in and out of the autoclave and saves construction areas.
7,Using the integrated process layout, it is conductive to building warm insulate and automatic control of the line. At the same time, it reduces the cost of construction.
8,Using hydraulic transport system instead of travelling crane can improve the stability of the system and save the procedure of application for inspection.
9,The waste on the bottom is cleaned by the hanger with cleaner and then sent to the autoclave kettle for autoclaved maintenance to realize no hard waste for production.
10,Comprehensive utilization of the waste material, waste water, waste gas and rain water helps make full use of the source and reduce emissions.
11,In order to simplify processing and reduce the cost of production, manual work is needed to clean and oil the molds.
