High Speed vs Low Speed Grinders - Whole Latte Love

2021-5-5  Low speed or high RPM grinders are usually lower cost grinders in the $200 or less range. They have lower RPMs for a couple of reasons. Usually they have smaller motors, and use gear reduction to step down to the smaller RPM. They also usually have smaller burrs, and most are conical shaped. The lower RPM grinders usually have less heat buildup.
