To provide a method for producing small particle size cellulose with excellent productivity, by which small particle size cellulose can be efficiently obtained from a cellulose-containing raw material.
The method for producing small particle size cellulose uses a continuous vibration mill in which first and second vibration mills are connected via a connection part, and comprises the following first and second steps. The first step: a cellulose-containing raw material having a cellulose content of ≥20 mass% in residual components obtained by removing water from the cellulose-containing raw material is processed in the first vibration mill packed with rods having an outside diameter of 20-200 mm to obtain cellulose having an average particle size of 40-200 μm. The second step: the cellulose obtained in the first step is processed in the second vibration mill packed with rods having an outside diameter of 3-15 mm to obtain small particle size cellulose having an average particle size of 1-38 μm.
