摘要： A production method for producing a particle mixture in which two or more types of particles are mixed, including a step of adding a first additive to first particles and mixing the first additive with the first particles using a first mixer and a step of introducing the two or more types of particles including the first particles mixed with the first additive and second particles into a blender container of a gravity blender, and mixing the two or more types of particles inside the blender container.
