you can do it with buildcraft pipes when you keep the following in mind:

first, suck out of the chest with a wooden transport pipe

next, get a distribution transport pipe on every macerator and set the first at 9 continiuing, 1 going into the macerator and so on

to sort the overflow out, get obsidian transport pipes powered by an engine like this

s

e

o

s is the stone transport pipe going into the macerator, e is empty space, o is obsidian transport pipe.

feed the overflow coming out of the obsidian transport pipes into an iron transport pipe only allowing items to go towards the chest, also feed output from earlier transport pipes into these.

then get the overflow pipe into the chest.

then the item gets out and continiues on.

this system is 100% overflow-proof and 100% accurate.
