That’s because it’s all hooked up to the shredder, and automatically sorted by the pipes. I’m using x4 storage drawers hooked up to hoppers as a pre-aluminium dynamic filter when the centrifuge outputs the dusts themselves, the dusts get immediately routed to the drawers instead of clogging the pipe to the shredder since they can’t enter it, and then re-enter the system through hoppers that are injected directly into the pipeline, the only thing I need to do is add another x4 drawer+hopper combo whenever I centrifuge some new ore. When I will get access to extrautilities’ item filters, I will be able to oredict filter dusts and get rid of the drawers altogethe (bit of a cheaty system because it relies on third party mods to do the gruntwork, but as it is I could achieve the same effect by using 4 times the amount of barrels as a buffer I suppose)
Pipes are doing a wonderful job by the way. I’ve got 2 full sides of the funnel already filled with different dusts, but they route everything perfectly without any trace of lag.
