When coffee beans enter, the coffee beans are between the conical grinding head 81 and the conical grinding teeth 92 in the grinding disc seat 9. The conical grinding head 81 is driven by the motor 3 to rotate rapidly. At this time, the grinding disc seat 9 remains relatively still, so that the conical grinding head 81 and the conical grinding teeth 92 fully grind and cut the coffee beans, so that the coffee beans are quickly converted into coffee powder. Based on the above two grinding disc schemes, both can be assembled based on the grinding disc seat 9, and the fineness or coarseness of the coffee powder can be flexibly adjusted, so there is no need to purchase a second set of bean grinding equipment, reducing expenditure costs.
