The crusher is a building for the space platform that crushes small asteroid chunks into usable resources. To collect the asteroid chunks, they must first be grabbed by an asteroid collector. There are three types of recipes that can be performed by the crusher:

• Basic crushing: These recipes break the chunk into a significant volume of one usable resource, with a small a chance of also reproducing the chunk it consumed. You have to design your crushing setups to deal with the chunk byproduct without clogging up the system.
• Advanced crushing: These recipes break the chunk into two useful resources, though at a lower volume of output than the standard crushing recipes. It can still regenerate the chunk, but it has a much lower chance to do so.
• Reprocessing: These recipes attempt to transform the chunk into a different kind of chunk. The original type is usually reproduced, with a smaller chance of producing a different kind of chunk or nothing at all. The chance of producing each chunk type is rolled independently, so reprocessing one chunk can potentially return up to three new chunks.

Circuit networks

Connecting a crusher to a circuit network allows setting its recipe automatically. Accepted signals include specific recipes and item signals for asteroid chunks or the outputs of any supported recipe; signals that correspond to unresearched recipes are ignored.

The recipe will be selected based on the following rules (in order):

• Signal type: Signals that specifically set a recipe > signals for items produced by recipes
• Recipe type: Crushing > reprocessing > advanced crushing
• Asteroid type: Metallic > carbonic > oxide
• Default item order
• Quality: Lowest > highest

For example, if the crusher is wired to a belt containing only oxide asteroids, the recipe will be set to oxide asteroid crushing. Adding a metallic asteroid (or iron ore) to the belt will change the recipe to metallic asteroid crushing, because that recipe has a higher priority. Reprocessing recipes can't be selected via item signals because all of the output items for those recipes are also shared with the asteroid crushing recipes.

Quality

The three asteroid reprocessing recipes are a great way to get high quality items since they have a return rate of 80 % as opposed to the 25 % of a recycler. The setup simply requires all asteroids being reprocessed until they are legendary. Afterwards a whole range of products can be crafted out of them. For the ratio of crushers consider the following:

• The chosen space route is irrelevant in the grand scheme. Since all asteroid chunks are reprocessed multiple times, their ratio balances out quickly.
• Within each quality level half as many crushers recycling oxide asteroid chunks than recycling carbonic and metallic asteroid chunks are required, since the former recipe is twice as fast than the other two.
• With better quality modules the number of crushers needed for reprocessing higher quality asteroid chunks increases. The two extreme cases as a guideline:

• With two normal quality modules in each crusher the optimal ratios are as follows:

• 100 crushers reprocessing normal chunks
• 15,52 crushers reprocessing uncommon chunks
• 3,96 crushers reprocessing rare chunks
• 1,01 crushers reprocessing epic chunks

• With two legendary quality module 3s in each crusher the optimal ratios are as follows:

• 100 crushers reprocessing normal chunks
• 37,30 crushers reprocessing uncommon chunks
• 17,64 crushers reprocessing rare chunks
• 8,34 crushers reprocessing epic chunks

The ratios can be calculated with the following formula:

$C_q=\frac{C_{q-1}\cdot Q\cdot \frac{9}{10}}{0.2+0.8*Q}+\frac{C_{q-2}\cdot Q\cdot \frac{9}{100}}{0.2+0.8*Q}+\frac{C_{q-3}\cdot Q\cdot \frac{9}{1000}}{0.2+0.8*Q}$

The variables are named as follows:

• $C$ Number of crushers.
• $q$ Quality level (e.g. normal: $q=0$). When $C_{q-n}<0$ that term has to be omitted. For example in order to calculate the number of machines reprocessing uncommon ($q=1$) asteroids only the first term is needed, since there is only one tier below.
• $Q$ Combined quality value of the modules inside the crushers.
