Can a 300W kitchen aid do meat grinding?

Kitchenaid mixers can grind meat, I know because I have one with the meat grinder attachment and I've used it do just that, as well as make sausages. The problem is one of expectation: it is not the biggest or the fastest meat grinder, if you are going to grind meat often and in large quantities a purpose built one is a better choice for you as it will be faster. However, if you don't need to grind often the kitchenaid one is a compact, effective and relatively cheap solution. It helps to cut the meat into manageable chunks that will fit down the throat.

I generally agree with @GdD. I use my kitchenaid as my only meat grinder, and regularly grind up to 5 - 10 pounds of meat for sausage and salumi making. I do have some tips to improve the experience. First, do not purchase the plastic Kitchenaid grinder attachment. Instead, purchase an all metal one. I believe Chefs Choice makes one. There might be others. This makes a big difference. First, there is less movement in the parts. Second, you can get it very cold by placing the parts in the freezer before use. This leads to my second tip, (and this is true regardless of grinder) which is to par-freeze your meat after you cut it into strips that will easily fall into the feed tube of the grinder.

In other news: I don't have, or use, the food processor attachment. I have used the pasta extruder (it sucks), but the pasta roller is a fantastic improvement over my hand roller.
