Fluidides bed sand clumping

Fluidides bed sand clumping

Fluidides bed sand clumping

(OP)
Hi there,
Could any one suggest as to why does clumping of sand occurs in fluidised beds ?
we get good results from carburising & Q&T 's.
we got new retort new diffuse & sand, all three month old
we got 16 grit above diffuser about three inches high and 120 grit just under flue exit.(Furnace height 2.2 meters)
Burn outs are been carried out after every carburise run
Burns at 880 for 3hours on air (3tn sand bed furnace)
and bringing it down to 500 on nitrogen then air takes over.
Do humidity has effect in clumping ?
Even seiving of sand didn't help starts clumping around three months.
Help me please
Cheers
