hi

we are using airslide to transport finish product cement to the silos. airslide is using aeration and gravity flow to transport cement powder.

but the problem is we have to clean and clear airslide especially at the 90 degree elbow when stopping for 2-4 days if not we are facing caking and next blocking problem.

do you have any solution/suggestion for this problem?

Caking problem may be due to following reasons-

1.Fliudised air is not dry.

2.Pressure is not correct.

3.Faulty design of 90 deg. divertor

Please send us the g.a drawing of that area and also design of 90 deg. divertor.

4. You can also install small lump crusher.

our climate has 55-65% of relative humidity and ambient temperature of 29-33 deg C,

how to get a really dry air from the blower fan since its only has the filter at the inlet to filter dust and particle.

our 90 degree diverter is just change overgate normally use in cement industry consist of 3 gates -top view just like crossroad only open one and close other two gates

Is the only problem you have at the 90 degree diverter? Do any of the other air slides in the silo or upstream of the diverter gate also block?

i can say if no clean and clear carried out at this part it will have high potential of blockage

we have some other critical area but most critical is at this 90 deg diverter

It sounds to me like the diverter has a "dead leg".

I would need to see the detail construction drawing to fully assess the design.

Dear Mall,

Try to put a space heater on the air pipe line between blower and inlet of airslide and 90 deg. divertor/elbow.Your problem will get solved.

space heater - i never see it, do you have the photo

we only use dryer for our main compressor for jet pulse of our bag filters but for the airslide it suck direct air from outside and blow it
