We classify our grinders into three categories. First, low volume grinders are typically made for home use. Commercial grinders are for coffeehouses, restaurants, and other commercial applications due to their structural robustness and larger grinding burrs needed to dissipate heat build up. Industrial grinders are for coffee roasters where large amounts of beans need to be ground for clients at a quick turnaround. Some grinders can fall into two categories as some clients, for example, want a commercial grade grinder in their home.
