Foam concrete block machine/Foam Machine working process

1. First the loader loads sand material into " material hopper" , the sand through belt conveyer enters into " ball mill machine" to crush into powder slurry. In the crushing process , water will be add into ball mill machine in the same time . So finally ball mill machine will produce sand slurry
 

2. Sand slurry out of ball mill machine enters into concrete pit , slurry will be send into two " slurry store " " (3) through " slurry pump"
 

3. When we need slurry to batch , the slurry be released from " slurry store mixer" and enter into slurry pit which under the " slurry store mixer" . There have another " slurry pump" take sand slurry enter into " slurry measure" slurry measure scale automatically. In the same time, the lime, cement , gypsum, will be added in to lime cement gypsum scale automatically one by one. After measuring sand, lime, cement, gypsum , they will be added into " slurry pouring mixer " automatically , In the same time , the aluminum will be add into " slurry pouring mixer " by manual after manual scale measure .When all material mixing in the " slurry store mixer" , after 4-6 minutes mixing , all material will be pour into " Mould box" .

Except that aluminum powder will be added by manual, the whole batching process is operated by PLC in control room.
 

4 After slurry be pour into mould box , " frequency conversion pouring ferry car" will take the mould into curing room area automatically , all the mould box will be add into curing room to cure automatically through PLC in control room
 

5 when mould box moving in the curing room , all mould boxing moving process is automatically , under mould box there will be roller that will support mould moving
 

6 After 1.5-2 hours pre-curing in curing area , the mould box with foam block will move into " reversal crane" position , reversal crane will lift and do the de-mould work, put the block with pallet on " cutting translational cart" , then there will have level cutting and vertical cutting process, the cutting processs willl be controllled in the control room automaticallly .
 

7 After cutting the block , It will be transported into steam trolley trough " transportt block crane" , the crane will be controlled by wireless control device , also there have the wire control device for spare alternating.
 

8 6 steam trollies {12 blcoks}will be sennt to autoclave through windless machine
 

9 In autoclave , sand blocks will need about 10-11 hours for steam . First we need 1.5 hour to discharge cool air from autoclave and 1 hour to add pressure, when it reachs 0.6 Mpa slowly , then use 0.5 hour to reach 1.0-1.3 Mpa quickly .

In 1.0-1.3 Map period , we need keep about 5-6 hours steam , after that we will need 1.5-2 hours to release the pressure and steam . After about 10-11 hours , the blocks could be taken out and transported in store area.
 

10 The empty pallet with trolley will be sent back to reversal crane and organize new moulds to reuse . Trolley will be transported for entering into autoclave area to re use.
