The rock melter is a useful way of obtaining lava without having to pump it from nether or deep in overworld. It takes power input from any engine attached, and converts it to heat that melts the rocks so separate heating is not required.
Rotarycraft Handbook DescriptionEdit
"The rock melter uses frictional heating to melt rock into lava, which can be drawn out with pipes. Netherrack provides the most lava per block while cobblestone provides the least.
|Max temperature||1,800 degrees|
Angular Transducer OutputEdit
- Source of power input, total power and speed
Temperature Requirements Edit
The Rock Melter needs to meet a certain temperature to process materials. The required temperatures are material dependant, see the table in the Duration of Operation Formula section for target temperatures per material.
For every tier of power input, temperature increases by 64 degrees. See the table for temperature increases at various power inputs.
Do note that the machine takes ambient temperature into account. Operating this in the nether will net you a 300 degree temperature bonus.
Final_Temperature = Ambient_temperature + log₂(Input_Power) * 64
Simply check the required temperature of the material you want to process against the table, apply the required power and it will process that material. Providing more power will increase the processing speed without any losses.
Duration of Operation FormulaEdit
The duration of operation depends heavily on the type of material/block you are trying to melt. Check the table for all the recipes melting energies.
|Cobblestone||Lava||500||1000||3.120 MJ / 2.82 MJ|
|Glowstone dust||Glowstone||250||400||80.000 KJ|

|Redstone dust||Redstone||100||600||120.000 KJ|
|Redstone block||Redstone||900||750||1.080 MJ|
|Ender pearl||Ender||250||400||240.000 KJ|

- ↑ Certain types of cobblestone will use the cheaper recipe
After the machine has reached the target temperature, it's stored energy increases by the input power once per tick. Once the stored energy exceeds the required energy for the recipe, an item is processed.
If the temperature of the machine is LESS than the target temperature then the stored energy will be multiplied by 0.85, meaning that 15% of the stored energy will be lost for every tick that the machine is below the target temperature.
Do note that the required energy is 20 times higher than the above listed, this effectively means that the processing speed is in seconds rather than ticks.
The formula for operational speed therefore is...
Time_In_seconds = Recipe_Energy_Required / Power_Input
Taking stone as an example, which as per temperature requirements above, requires 65.536 KW of power to process will be processed once every 79.35 seconds.
Tips & TricksEdit
- Other heat generating and/or cooling machines can be used to control the temperature of this machine. However, you don't gain anything other than potential operational speed by doing so. Materials still have a fixed energy requirement so you would be better off meeting the required power input level. But... In a pinch... You can.
