The Extractor is a machine added by the RotaryCraft mod. This machine is used to multiply ores, similar to the macerator from IndustrialCraft. Unlike the macerator, it doesn't just 'double' the ore, it has four separate stages of operation that each have a 50% chance of doubling that part of the ore. On average, the player will get 5 times the ore that is inputted. Each stage of operation has different requirements to operate, but all are done in the same machine.

The Extractor can be upgraded with a Bedrock Drill which makes the first stage have a 100% chance of doubling the ore.

Note that the power input is the bottom of the machine, so a Bevel Gears is needed to input it.

Rotary Handbook Description[edit]

The extractor is used to get more material out of ore. First, it grinds the ore to dust, then mixes it with water to form a slurry, then presses that slurry through a filter to obtain a liquid solution, then burns the result to obtain ore flakes. These flakes can be smelted in a furnace to obtain a unit of the ore's material. Each stage in the extractor has a 50% chance of doubling the output. The machine's requirements are complex and vary from stage to stage, but a supply of water and 512 Nm of Torque at 8192 rad/s will run all four stages.

Notes: Stages 2 and 3 require a water supply.

Operation Stages[edit]

After solving the equation 'Power = Torque x Rotational Speed', the solutions (requirements) are:

Stage Power Torque Speed
Stage 1 65536W 512 Nm 128 rad/s
Stage 2 16384W 8 Nm 2048 rad/s
Stage 3 32768W 4 Nm 8192 rad/s
Stage 4 65536W 256 Nm 256 rad/s

It should be noted that the torques for stages 2 and 3 are only 8 and 4 when you operate at that minimum speed requirement. If you pump additional power in via Speed-increase-only (32768 rad/s * 1Nm, for example), the power requirements are met at 1 Nm.

Extractor (RotaryCraft)

Simple set-up[edit]

A few other machines are needed to use this set-up, but they are all basic machines that won't be hard to use.

One of the simple ways to set up this machine for all operations is to have a Gasoline Engine, a Steel 16:1 Gearbox, Bevel Gears, and the Extractor. Water needs to be piped into the Extractor (in the back works and buckets can also be used), and lubricant is needed for the gear box. Lubricant is made from the Grinder and can be piped into the steel gearbox. Other types of gearboxes may be used, but the steel one has a lot more durability and isn't that hard to make.

For the Gasoline Engine to run, the player will need Ethanol Crystals, which are made with the Fermenter.

The 16:1 gearbox will connect the engine to the bevel gears, and the extractor is placed on top of the bevel gears. The gearbox has 2 modes of operation, one of them will successfully power Stage 1 and Stage 4, while the other direction will power Stage 2 and Stage 3. In order to switch the direction, shift-right-click with a Screwdriver.

A slightly more complicated setup can be done with stone gearboxes if you are really strapped for steel (a 16:1 steel gearbox requires ~30 ingots). Instead of using a Steel 16:1 Gearbox, run your power through a Stone 2:1 Gearbox (set to speed mode) and then a Stone 8:1 Gearbox before the bevel gears. This also has the advantage of running the first and last stages about 15% faster. Disadvantages are that stone gearboxes consume more lubricant and that the 8:1 needs to have a heat fin or else it will become damaged when running in 8x speed mode.

Maximum speed[edit]

To run the Extractor at 1-tick operation speed you need, at a minimum, 16 MW of power and gearboxes capable of handling 1 Mrad/s (diamond or better). Note that this is the minimum for individual stages; only part of the machine will run at 1-tick speed with 16 MW. The easiest ways to produce this amount of power are:

  • A Gas Turbine (67 MW, can be throttled down with an ECU to 16 MW for less fuel consumption)
  • A Graphene Battery (needs to be "charged" with other RotaryCraft engines, only available if ElectriCraft is also installed)
  • 2 Tier 4 Magnetostatic engines and a shaft junction (will consume 55.6 kRF/t and 36 mB/sec Liquid Nitrogen)
  • A Tier 5 Magnetostatic engine (will consume 64.5 kRF/t and 23 mB/sec Liquid Nitrogen)

Note that you will need a fair bit of RotaryCraft infrastructure built up to craft the high-tier Magnetostatics. You won't be able to jump right into the mod at that point and skip all the lower-tier machines. Among other things, a tier 4 will require an already-functional Extractor setup and 4 MW to have a working Bedrock Breaker. A tier 5 will require at least 21 MW with the right speed/torque ratio going into a friction heater in addition to that.

Supplying 512 Nm @ 32,768 rad/s will run the high-torque stages (1,4) at 1-tick speed while 1,048,576 rad/s (and 250 mB/t of water) will run the high-speed stages (2,3) at 1-tick speed. The best way to manage this is to use a redstone-controlled CVT Unit which has a difference of 32x between the on/off states and a redstone clock to toggle modes. An example setup would be a Gas Turbine going through a 16:1 gearbox (diamond or better) set to 16x speed, followed by a CVT set to 8x Torque / 4x Speed.

Running all stages at 1-tick speed simultaneously requires about 537 MW, which is infeasible to generate without ReactorCraft and only processes ores (at best) twice as fast. With the same amount of power, it would be more efficient to run 32 copies of the above setup in parallel instead.
