A Compactor

(Insert a detailed description of the machine here)

Rotarycraft Handbook DescriptionEdit

The compactor can compress coal until it becomes anthracite, then prismane, then lonsdaleite, then diamond. Each state will require four of the input items per unit output. All steps require enormous pressures of 550,000kPa and temperatures of greater than 800C to take place. The compactor will gradually heat or cool depending on its surroundings, and pressure is built up by applying high torques.


Minimum Power:

Power 524288W
Torque 4096 Nm
Power Input Back

Power needed to compress coal*

Power 4,194,304 W
Torque 4,194,304 Nm
Power Input Back
  • To compress coal a massive amount of torque is needed. One method to generate the needed torque is to use a Tier 2 Industrial Coil (240TJ max). Set the Industrial Coil to 1024 rad/s and 4096 Nm, then use 2 CVT units both set to 32:1 and set to torque. This setup will provide enough Torque to achieve the needed pressure to compress coal to diamond. (Note: This processes will take a few minutes to achieve the needed pressure and it will take a few minutes to perform the compression processes. This system will require a lot of power. It will consume about ~15GJ of power per hour.)

Duration of Operation FormulaEdit

  • Stage 1: Time(in ticks) = 300 - 15 × log₂(speed + 1)
  • Stage 2: Time(in ticks) = 600 - 30 × log₂(speed + 1)
  • Stage 3: Time(in ticks) = 900 - 45 × log₂(speed + 1)
  • Stage 4: Time(in ticks) = 1200 - 60 × log₂(speed + 1)

Tips & TricksEdit

The Compactor is affected by the ambient pressure, which in turn is affected by height, dimension, and if the compactor is under a fluid. Setting up the compactor in these locations will decrease the pressure (and therefore torque) you have to add to the machine. Here is a list of some default ambient pressures.

  • Ambient (Overworld 30 <= y <= 128) = 101kPa
    • y < 30 = 126.25kPa
    • y > 128 = 80.8kPa
    • y > 192 = 64.64kPa
  • Ambient (Nether 30 <= y <= 128) = 20,000kPa
    • y < 30 = 25,000kPa
    • y > 128 = 16,000kPa
    • y > 192 = 12,800kPa
  • Under Water = 10kPa increase per meter of water (this is added to the ambient)
  • Under Lava = 27kPa increase per meter of lava (also added to ambient
