How does the quartz grindstone/pulverizer work? | Feed …
Mar 31, 2013. #5. you need to pulverize/grind the ores, not the ingots. pulverizing ores gives 2 dusts (and the pulverizer gives some secondary dusts sometimes) and then you can smelt the dusts to ingots. pulverizing ingots just gives 1 dust and no secondary dusts, else you have a never ending cycle of pulverizing and smelting.
