Main features of Hongfa AAC project:

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.

About the raw material ratio of AAC block :

Cement lime fly ash style aerated block raw material proportion

Cement lime Sand style aerated block raw material proportion

Reference: cement is 42.5 Portland or 42.5 common cement

Aluminum power paste calculate to use according to 600kg/m3 
Remark: the accurate batching rate is adjustable according to the raw material locally
