Use the following table to help you match your application to the proper grinder. If in doubt on the size of the grinder you need, consider the next size up so that you are ready to meet the growing needs of your operation. Our commercial grinders and the KE640 on-demand espresso grinder are UL and cUL approved as well as ETL approved and tested to meet NSF-8 requirements. (Models KFA1403 and KF1800 do not carry the NSF seal).

All of our grinders give you the same uniformity and consistency over the entire range of settings. The main difference is in the speed of the grinding.

If you need a coffee grinder and volume and speed are not an issue, our 804 or 805 series grinders would get you started with a quality grinder to satisfy any application. If you expect to grind a lot of coffee during the course of the day, choose model KR1203. If you have 220 volts / 3 phase power available, consider the model KR1403 instead of the KR1203--for only a little bit more, you will get 60% more grinding speed, and the 3 phase grinder can be used non-stop, even for 8 hours straight. Before you order a 1403 or 1800 series grinder, make sure you have THREE PHASE power available in your store or roasting room.
