The coffee grinders in this section are the largest of the coffee grinders in the "Personal Coffee Grinders" section, and the smallest of the coffee grinders in the "Commercial Coffee Grinders" section. Coffee grinders that are 10 pounds or more can be used in light commercial applications, i.e., in coffee shops that use their coffee grinders to grind a just a couple of pounds of coffee per day.
If you are running a larger shop, and will use your coffee grinder to grind more than a few pounds of coffee per hour, you should choose a coffee grinder from the "Commercial Coffee Grinders" section. With the possible exception of the Rancilio MD 40 coffee grinder, which can grind up to 8 pounds of coffee beans in an hour, the coffee grinders here are not meant for very heavy use.
But if you are running a small coffee shop, the coffee grinders in this section may suit your needs. Do not get a coffee grinder smaller than the coffee grinders in this section for commercial use.
