The raw materials of the filter media were originally integral. In order to make it adaptable to various filtering occasions, the filter media must be crushed to a suitable particle size. When the filter media is crushed, the filter media obtained by crushing is not a uniform sphere, but an irregular crushed entity. It takes some effort to determine whether the particle size of the filter media meets the crushing standard.
