WHAT IS A CONICAL BURR GRINDER?
Essentially, the primary difference between the conical and flat burr grinder is the shape of the rings and blades. Conical burr grinders consist of two cone-shaped rings that are bladed, one facing upward, the other facing downward. As the beans travel between the blades, they are not sliced but are “chewed” down by the burrs in order to form grounds.
There are also several benefits to the burr grinder that many coffee lovers enjoy. They provide a high level of control over the grinding process and also do a great job of maintaining low heat levels, which is important because the oils in your grounds are very vulnerable to sudden increases in temperature. Conical burrs are also much quieter and require less amount of energy levels to operate.
