PROBLEM TO BE SOLVED: To provide a method for pulverizing the natural organic matter residue which is separated from necessary components that have been extracted from natural organic matter is pulverized at a low cost to promote recycling use thereof and which can be extended into new recycling use. SOLUTION: The natural organic matter extraction residue such as tea or coffee is pulverized by a screen mill 5 provided with a cylindrical body 51, a rotary cylindrical body 52, plural rotary blades 60 formed on the rotary cylindrical body 52, and plural fixed blades 61 formed on the cylindrical body 51 into natural organic fine powder of average particle size of 300μm or less. Since it is pulverized by the screen mill 5, pulverizing cost is reduced to promote recycling use.
