Can you try with IC2 installed? Try macerator recipes.
试试安装工业2有可能有用（打粉机）

Will try asap, but btw I believe the ultimate goal should be something that can be pulverized in any mods’ macerator instead of single compatibility with IC2 machines.

When rock crusher is ported back, the recipe will be in rock crushers.

Ref #1373.

Done in 1.12.
