This is a re-upload of a project I originally posted to curseforge, that I have since removed. I've posted it to modrinth for posterity sake, but it will likely receive no future support. The following is a verbatim copy of the original curseforge description.
Better grinder is a fork of the Plain Grinder mod by Lothrazar. While I can respect the original vision of the mod, it had a few major issues and missing features that I was really frustrated by, so with the help of Ferri_annus (AKA I paid them to do all the code stuff while I made the textures) I'm happy to release Better grinder!
So what is Better grinder outside of that context? It is a simple mod that adds the most basic ore grinder possible, heavily inspired by the original AE2 quartz grindstone. You place the grinder block down, attach a handle, and every full rotation of the handle completes one recipe. By default it adds a few simple recipes that let you grind vanilla ores into 2 dust each, which can be smelted into ingots, allowing you to produce more metal per ore!
However this mod is rather barebones by default, and the intention is mostly for it to be used by modpack developers, who can add custom recipes for it using datapacks or crafttweaker.
The main issues that better grinder fixes and/or adds to the original mod is as follows:
-Uses the default recipe registry, allowing people to remove the default recipes via datapack or Crafttweaker.
-Adds the capability for chance based outputs, which isn't used by default, but can be used by packdevs to Include recipes that have a certain percentage chance to give either a primary or secondary output.
-Adds a secondary output slot, that isn't used by default, but can be used by packdevs to add a potential second output to a grinding recipe.
-Compat with hand cranks from other mods via blocktags. By default additional compat only exists for the Create hand crank and the supplementaries crank, but hand crank blocks from other mods can be added to the plaingrinder:cranks block tag to include compat for them!
-Built in Crafttweaker support! to make adding your own recipes even more of a breeze.
-Hopper compat, allowing you to insert items via the side, and extract them from below.
-Upgraded textures, by yours truly!
Example Crafttweaker recipe: https://gist.github.com/Warhand/928798bca891bbb47f555e63a50ddbe6
//this recipe will consume a wooden axe, with a primary output of 2 clocks, and a 50% chance of giving you a powered rail as a secondary output.
Example Datapack recipe: https://gist.github.com/Warhand/f3d1f2f499e7e4f139fce8f61294b503
This recipe will consume 1 stick, and give you a primary output of 64 diamonds, and a 50% chance of giving you a secondary output of 32 emeralds
