i hope you are not designing for any industrial use.If so then it is very coplex process.If not then try with cyclone seperator.This type of seperator is for sure seperates dust and carbon particles.Only you have to quantify the flow measurements.This is some sorts of gravity seperator.
i guess your load condition is the torque type.The normal failure in toque is due to section variation.anyways if you are using any kind of stress analysis software failure should be detectible.
Can any one tell me what storage device(it's a pcb ith some chip on it) Renold smart link is using? If it is avilable in market(only the storage unit alone) pl let me know.
I need a smallest analog storage device.
