Three employees were attempting to unplug the drop chute on 2-1 & 2-2 hammermill. The EE was hitting the chute about 10 times with a pry-bar. They hit their left pinky finger against a piece of angle iron that is attached to the hammermill drop chute. The EE noticed blood on the piping. They received a laceration to the finger. EE was given 5 stitches and restrictions.
