摘要：
There is disclosed a coffee grinding machine for grinding coffee beans and forming a dose of ground coffee directly in a filter basket with a bottom layer of ground coffee having a first mean particle size and an adjacent layer of ground coffee having a second mean particle size, comprising: grinding members for grinding coffee beans, an electric motor for causing rotation of at least one grinding member with respect to another grinding member, and a device configured to cause, during grinding of coffee beans for forming dose, a variation of rotation speed of said electric motor between a first speed and a second speed, wherein either said second mean particle size is smaller than said first mean particle size and said first speed is greater than said second speed or said second mean particle size is greater than said first mean particle size and said first speed is lower than said second speed.
