Special bean grinder for Italian coffee machine (Grinder)

Because the coffee machine extracts coffee with high temperature, high pressure and fast extraction, it has special requirements for grinding degree. If the grinding degree of the bean grinder is not fine enough, it will lead to insufficient coffee extraction; if the grinding is uneven, it will lead to uneven extraction. Generally speaking, the bean grinder can only grind the coffee powder into coarse particles, and the grinding can not be very uniform at the same time. On the other hand, the special bean grinder of the coffee machine can grind the coffee beans into a fine powder (with a certain sense of particle), so there is a special bean grinder next to the coffee machine.
