GB/T 44750-2024 "Particles — Measurement of compressive strength" specifies the method for measuring the single-particle compressive strength of particles. It is applicable to various types of solid particles (such as catalyst particles, fertilizer granules, ore particles, etc.). The standard clarifies the requirements for sample preparation, including particle size screening, quantity selection, and pretreatment conditions. It also standardizes the technical parameters of the measurement equipment (such as loading rate and force accuracy). By applying axial pressure to a single particle until it fractures, the fracture force is recorded and the compressive strength is calculated. Additionally, the standard requires repeatability verification and data rounding, providing a unified method for evaluating the strength characteristics of particles.
