Coffee grinders are classified into two: burr grinders and blade grinders. As the name suggests, blade grinders make use of blades in grinding coffee beans. Burr grinders, on the other hand, utilize grinding wheels. Blade Grinders Blade grinders are compact, making them more appropriate for home use. That also mean they require less space. However, their small size also entails less capacity. For commercial use, it is less beneficial than burr grinders which tend to have higher capacity. These grinders require more effort to run, as well. You need to constantly monitor this machine to ensure that it grinds the coffee beans based on your preferences. Perhaps, the main advantage of blade grinders is their affordable price. This is because they require fewer materials for their production. They have minimal automations as well. Today, the more advanced machines are also more expensive. That is because these automations lessen your work. When it comes to operational costs, blade grinders also appear less expensive. This is due to the lower wattage required for their operation. Burr Grinders These coffee grinders are bulky. One reason for their size is the motor needed for them to operate. Another factor is the container for the coffee beans. The large container means greater capacity which further means you can grind more coffee in less time. This time-saving feature is perfect for coffee shops that serve numerous customers at a time.
