Produces 420 graphite/min from 420 coal. The system requires hydrogen input to operate. It consumes a very small amount of hydrogen constantly (~20/min) this is required to self recovery.

Add a small amount of refined oil into the inner oil belt. The system will generate the required oil first. This will consume a small amount of coal in the beginning; once it's done, no extra coal is consumed.

NOTE: Please do not upgrade belts. It requires green belts to operate.

Key benefit: clog resistant. It can self-recover eventually by burning excessive hydrogen and converting excessive oil into graphite.
