Ok, so I have a set up. Ores coming from my quarry go through a sorting machine and from there to pulverizers. From the pulverisers I have relays which feed into filters so that I can have them filter out dusts from ores that I don't want smelting. My problem is is that the dusts collect in relays and wont go through the filter and I can't figure out why... Here are some images
Edit: I've resolved the issue by including a chest for the dusts to collect in and then simply moving them out manually. I don't intend to keep using RP2 for much longer.
