A test method of falling strength of fluorite pellets

A method for testing the falling strength of fluorite pellet was introduced.Its principle was to freely drop a certain amount of fluorite pellets from a specified height onto a steel plate with a specified thickness,and the falling strength was expressed as the percentage of the mass of the fluorite pellets with a particle size larger than 10 mm to the mass of the original fluorite pellets.The experimental equipment and sample processing methods were introduced,and the basis for the selection of experimental parameters was discussed.The results showed that the falling strength of fluorite pellets measured by this method was stable and the data was reliable.
