China AAC block plant Manufacturer, 1.advanced technology, 2.fully automatic system, 3.12years experience, 4.ISO9001:2008 - details see: https://www.machineto.com/hot-sale-in-2013-best-china-aac-block-plant-manufacturer-10075800

Welline manufacture high quality AAC block Plant:

We are a leading manufacturer of block making machinery in China with a history of 12 years.

We have several kinds of AAC block equipents manufacturing lines including AAC cutting machine,Storage tank,pouring mixer,ferry cart for pouring,moulds,tilting hanger,separating machine etc.,We can supply full set of autocl;aved aerated concrete equipments with 50K-300K m3 apacities annually.
Our AAC production line is importing German advanced equipment, through digesting, design and more perfect.

Our production line is popular in home and oversea.We provide turnkey service to our customers,including plant design,equipments installation,technical instruction,personal training etc.and also can design and manufacture as per clients' requirements.

Our equipment is advanced, we use Aerial tumbling cutting units.PLC automatic ingredient, complete electric control system.

Main equipments in AAC production line:

AAC block production line process:

1.Processing and storage of raw material:

Sand will be delivered to the plant via self-dumping truck and stored on the open yard. Bagged lime will be delivered to the plant by truck .Bagged gypsum powder will be delivered to the plant by truck Cement will be delivered to the plant via bulk tank truck .Aluminum powder or aluminum paste packaged in either barrel or bag will be delivered to the plant for temporary storage.

2.Batching and pouring:

When all kinds of raw material are ready, batching can be performed. Material in powder form (including lime, cement and gypsum) will be sent to powder metering scale for metering and weighing according to the given proportion. Sand slurry and recycled scrapped slurry will be sent to liquid metering hopper for scaling to the given proportion. As to the aluminum suspending liquid, Then the slurry will be poured into one mould.

3. Pre-curing (stopping and maintenance):

Slurry begins to foam after it is being poured into the mould and become preliminary curing. It will become the “cake” in 2 to 3 hours after stopping and pre-curing in the pre-curing room.

4.Cutting:

Cutting of “cake” shall be implemented after completion of foaming to form various sizes of product. Scraps formed during cutting will drop into the trench beneath the cutting machine and will be flushed by water into the scrap. Cutting and preparation of recycled scrap slurry will be controlled by the microcomputer program.

5.Autoclaving (steaming):

After completion of grouping the queued “cake” will enter the autoclave for steaming and hardening. Normally the autoclaving is in one cycle of 12 hours,

6.Post-autoclaving and finished product:

When the hardened finished product is hauled out of the autoclave, it will be handled onto the return line for side panel by use of the crane, then will stop at the block separating machine for separating. And then the finished product will be moved onto the wooden pallet placed onto the conveying line .
