Selection of Bean Mill effect of Bean Mill on Philharmonic Coffee

I have a rotary blade bean grinder. Do I need to buy a more expensive bean grinder that can grind more finely to maximize my Philharmonic pressure?

A: we have tested many of these bean grinders and found that the results are also very good. We only need to grind them a little longer than suggested in the manual. You can try a grinding time of two tablespoons for 30 seconds. When the fineness of espresso is reached, pink coffee may stick to the bean grinder because of static electricity. You may need to take out the coffee with the help of a spoon. Two tablespoons of finely ground coffee may require Philharmonic to press and filter for 20-30 seconds. The thicker powder filter makes the coffee a little lighter.
