Cluster grenade — Factorio Production Calculator
Cluster grenade is crafted in the assembling machine in 8 seconds, producing 1 per craft from 7 × Grenade, 5 × Explosives, 5 × Steel plate. At 60 per minute you need 16 assembling machines, and the chain behind it draws on 4 raw resources: coal, water, iron ore, petroleum gas.
Production chain for 60 Cluster grenade / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 3,600 | 192 | Furnace |
| Grenade | 420 | 112 | Assembling machine |
| Explosives | 300 | 10 | Chemical plant |
| Steel plate | 300 | 80 | Furnace |
| Sulfur | 150 | 1.25 | Chemical plant |
| Cluster grenade | 60 | 16 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Coal | 4,350 |
| Water | 3,750 |
| Iron ore | 3,600 |
| Petroleum gas | 2,250 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Cluster grenade recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 8 s | 1 | Grenade × 7, Explosives × 5, Steel plate × 5 |
What the whole chain needs
60 cluster grenades per minute pulls in 5 intermediate products, and the whole tree comes to 411 machines across 3 machine types, fed by 4 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 4,350 per minute, which is 4.83 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses cluster grenade
No base-game recipe consumes cluster grenade — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What cluster grenade is made from
- Grenade — 7 per craft
- Explosives — 5 per craft
- Steel plate — 5 per craft
FAQ
How many assembling machines do I need for 60 cluster grenades per minute?
16 assembling machines. One at standard speed produces 3.8 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does cluster grenade take?
At 60/min the chain consumes 4,350 coal per minute, 3,750 water per minute, 3,600 iron ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
