I needed a lot of netherrack for glowstone dust making, so I created this machine. It uses the principle of when netherrack is crushed in the crushing wheels you get more than one cinder flour. One cinder flour is mixed with lava and cobble stone to make nettherrack. So you are multiplying the netherrack every time you send through the process. I incorporated Triobian's cobble stone generator into this build.

You will need either an infinate lave source and about 6k netherrack to get full production rate of ~16k of netherrack an hour.

It is 13 wide by 26 long by 12 high and uses 24,000su. It produces approximately 16k of netherrack an hour once the holding vault & belts to the crusher are full.

See Triobian's YT video on how to set up the cobble stone generator, then run it to build up 10K of cobble stone, load up your netherrack either on the belts or into the two netherrack vaults and start the netherrack side of the machine.
