The Grinder is a wall placed Damage Trap introduced in The Squeeze, level 22 and unlockable by purchase in Orcs Must Die 2. It sucks in enemies that come within range and grinds them up into easily managed and dead giblets. A nice perk about this one is that it will run constantly until it jams. At which point it will need to clean and reset itself for the next period of use.

This works great against Kobold Runners, but is worse than other traps against the horde. Put one near the end (with barricades) to catch any that get by your main traps.
It is extremely effective when paired with barricades that force the horde to bottleneck past several grinders.
