Hello!

This is my Cobblestone refiner, it processes a doublechest of cobblestone within 3-4 minutes.
It is tested and working in 1.19.2, 1.20.1 and 1.21.1 with Create 5 and 6.
It outputs Iron, Gold, Andesite Alloy, Clay, Flint and Netherquartz.
It has some redstone logic built in to turn off sectors of the machine to prevent overflowing belts and chests, just attach a redstone link to your storage and the machine will stop outputting this specific item when the chest is full.

To run the refiner at full capacity(256rpm) you will need a rather fast cobblestone generator.
After placing the schematic, the filters might all be empty, in the gallery you will find screenshots for all filters.
