  • Motor– This is the most important part of a meat grinder which determines the sturdiness of a grinder. A residential grinder has a motor with 300 to 500 W.

  • A user then put the pieces of meat on the hopper and manually put the pieces of meat into the feeding tube.
  • The meat passes through the feeding tube and it reaches the extruder which pushes the meat to the outside.
  • The outer portion of the tube has a grinding plate and blade. The blade cut down the meat but the size of the cut depends on the size of the hole of the grinding plate.
