Home meat grinders, small appliances used to grind boneless meat of almost any kind,  beef-pork-lamb-chicken etc  to make hamburgers or sausage.

They vary greatly in price ($50-$200) and quality, they come in electric or hand cranked models.

Most meat grinders today are bought  by hunters or those who raise their own meat, they can be very useful to consumers who do not like to buy commercial ground products.

You can find attachments for home grinders and mixers, my experience with those is thew tendency to "mush" the meat rather than "grind', thus losing a lot of juice in the process.

I use a hand crank model at home, it grinds about 3 lbs per minute.

Both kinds work the same, meat is added through a "hopper" and pushed slowly with a plastic plunger while "cranking" with a handle, or, if electric,  the motor turns a meat shaft, called a worm, which pushes the meat throughy the plate/knife combo, it comes out ground meat.

There are different size plates, size being determined by the size of the holes in the plate, a 3/16" plate is standard for home use.

There is quite a difference in price between hand cranked and electric.

Hand cranked models are economical and appropriate for home use.

Home grinders are great for making sausage, it allows the home owner to experiment with small batches.

Many different types of boneless meat can be ground into burger and sausage. Favorites are pork, beef and chicken, but any boneless meat can be used.

Once you start making sausage and hamburger yourself you will never buy commercial products again.
