Steam Grinder

The Steam grinder is a macerator multiblock added by GT++. Although it behaves much like other GT++ multiblocks, it is notorious for being available at the steam age, being powered by steam rather than EU, and not needing maintenance.

Construction
The steam grinder is a 3x3x3 hollow multiblock. The controller must be placed in the front center. It requires steam-tier input and output busses ("Input Bus (Steam)" and "Output Bus (Steam)", respectively), and a steam hatch. Higher-tier hatches and busses will not work. The other blocks are bronze plated bricks.

Crafting the bronze plated bricks and the input and output busses needs only tin, copper, gold, and clay. The controller also requires 2 diamonds and 2 pistons, and the steam hatch needs one steel plate.
