I have just started playing Tech Reborn, just got my first pair of machines, the generator and the grinder, and weirdly my grinder won't grind any raw ores variants at all, resources like bauxite that drops ore is still grinded normally but any resource that drop "raw" pieces wont grind(lead, silver, iron, ...). I have tested in creative that the grinder still grinds iron ore, lead ore, ... but wont grind raw iron, raw lead, ...
Im currently playing on Fabric 1.21, mod version 5.11.9 (latest at the time of posting)
This has make the grinder kinda useless in survival early on, Is this some bug with the latest release only?

Wait, my bad for not checking more clearly, but it seems that it grinds ore into raw ore, but isn't the grinder for early game, isn't it a bit unfair to make ore doubling available for players with access to silk touch?

just get silk touch (find a village 😎 its intended behaviour btw)
