INSTRUMENT FOR DETERMINING CRUSHING STRENGTH OF PARTICLES [PDF]

open access: yes, 1963
An instrument for crushing-strength determinations of uncoated and pyrolytic-carbon-coated fuel particles (50 to 500 mu in diameter) was developed to relate the crushing strength of the particles to their fabricability. The instrument consists of a loading mechanism, load cell, and a power supply-readout unit.

Effects of the Particle Shape and Size on the Single-Particle Breakage Strength

open access: yesAdvances in Civil Engineering, 2022
The strength and deformation of a soil foundation are related to the strength of each particle. Maybe the shape affects the strength of a particle. In this study, single-particle breakage tests were conducted on limestone particles of different sizes to ...

Crushing strength of HTGR fuel particles

open access: yes, 1976
The whole-particle crushing strengths of High-Temperature Gas-Cooled Reactor fertile and fissile coated particles were measured and correlated with fabrication procedures. The crushing strength of Biso-coated fertile particles was increased by the following factors: (1) increasing the outer coating thickness by 10 $mu$m increased strengths by 0.3 lb (1.
