Cobble Pulverizer

Cobble Pulverizer
The Cobble Pulverizer is a technical construct in Dark Frontier. It processes cobblestone into gravel, but has a low chance of producing sand, flint, or gunpowder rarely.

Creating and Operation
To create a cobble pulverizer, place a Nether Brick Fence on top of a Dropper facing up. Place an anvil on any touching side of the dropper. To use it, load the dropper with cobblestone, then right click the fence with an empty hand.
