The crusher is a block which can crush/grind items into other items. Additional recipes can be added with data packs. The crusher requires Forge Energy to work. Energy is used at a fixed rate while the machine is working, and no energy while it is not.

Recipes can be added with data packs. The files can be anywhere in data/*/recipes/ (where * is the namespace of your data pack). The recipe type is silents_mechanisms:crushing.

Crushing recipes can have up to four output items, with an optional chance value on each. For example, crushing iron ore has a 10% chance of producing a block of cobblestone in addition to two iron ore chunks (100% chance).

• process_time - The time (in ticks) required to process one input item. Energy used per tick is constant, so this also affects the total energy consumed.
• ingredient - The item which is crushed. Same as with vanilla smelting/blasting/smoking recipes, this can be an item or a tag.
• results - An array of result objects. Each object can have these properties:
  • item (required) - The item produced
  • count (optional, default 1) - The number of the item produced
  • chance (optional, default 1.0) - The chance (out of 1) this output will be produced
