Legendary Coal from Grenade Upcycling
This book contains two versions of a factory that makes legendary coal by upcycling grenades:
- Normal-building version: produces about 123 legendary coal/min and 62 legendary iron plates/min.
- Legendary-building version: uses legendary assemblers and recyclers, and produces about 230 legendary coal/min.
Both versions make legendary coal by upcycling grenades. Grenades of every quality, including legendary grenades, are recycled.
To use
- Make sure your coal miners and iron plate foundries use quality modules.
- Keep enough miners/foundries that the normal-quality output remains at the required rate:
- Normal-building version: one full turbo belt of normal coal, 240/s.
- Legendary-building version: two full turbo belts of normal coal, 480/s.
- Connect your normal coal to the right side, connect quality coal to the left side and remove the simulated inputs.
- Connect all other inputs as well (lava, calcite).
- Connect power.
Notes
- The left side uses simulated inputs matching the expected miner output rates. They are only there to verify that the factory can handle the full expected input mix; replace them with your own production.
- The original version uses normal-quality assemblers and recyclers.
- The legendary version requires legendary assemblers and recyclers.
