Abstract
The manufacturing method includes a granulation step. The granulation step is a step of forming a plurality of granules by performing extrusion granulation on a granulation material using a granulation machine. The granulation machine includes a die. A plurality of through holes that allow the granulation material to pass therethrough are formed in the die. The plurality of through holes include first through holes having a first diameter, and second through holes having a second diameter that is smaller than the first diameter.

A method for manufacturing an excrement treatment material comprising:
- a granulation step of forming a plurality of granules by performing extrusion granulation on a granulation material using a granulation machine,
- wherein the granulation machine includes:
- a die in which a plurality of through holes that allow the granulation material to pass therethrough are formed,
- a rotation shaft that is located at a center portion of the die, and
- a roller that pushes the granulation material into each of the through holes while revolving around the rotation shaft,
- the plurality of through holes include first through holes having a first diameter, and second through holes having a second diameter that is smaller than the first diameter, and
- the second through holes are provided at positions farther from the rotation shaft than the first through holes.
