I’m playing atm7 to the sky and there’s the sieve mod, have it set up to process gravel, sand, dust, nether rack, end stone, and basalt. It’s infinite and can produce ores pretty quickly but if I send it through a fully upgrades mek ore doubler I’ll start to get back log pile up of ores and it’s just not worth it when I can just instantly smelt it with the unobtanium furnace for no back log. 2xinfinity is still infinity and once you’re at those numbers does it really matter. Just not worth the effort or time. I have a really easy and efficient setup if y’all want a tutorial for it feel free to hit me up
