The Lumber Mill is a dangerous locale where death was known to lie within the spinning cylinders of the combine. It was here that weapons of war were created from supplies of wood for the barracks. Catapults and other such weapons were produced for the legions that make up Shao Kahn's Outworld army.
This lumber mill became a place of kombat during the events of Mortal Kombat: Armageddon. Kombatants had the option of beating their opponent to death, or taking advantage of the giant grinder that would tear their opponent to shreds.
The spinning cylinders of the combine can be used as a death trap. The victim will fall between the grinders. As their body is ground up, their head will clash to the screen, leaving some blood on it as an effect.
