To understand why coffee grinding is so important to your morning routine, we must first look at the chemical reactions that occur when coffee is roasted. When coffee beans are introduced to the heat of the roaster, amino acids and sugars combine and begin a profusion of reactions that ultimately create the smell, taste, and color of the coffee.

Ultrasonic-assisted grinding processing can effectively reduce the surface roughness and enhance the processing efficiency in the processing of hard and brittle materials. However, the most common ultrasonic assisted grinding is a type of contact ultrasonic grinding where the grinding tool directly contacts the workpiece, which means that it is necessary to accurately control the pre-pressure ...
