一种萤石球团落下强度的测试方法

A test method of falling strength of fluorite pellets

介绍了一种萤石球团落下强度的测试方法,其原理是将一定量的萤石球团从规定高度处自由落下至规定厚度的钢板上,以粒度大于10 mm的萤石球团质量与原萤石球团质量的百分比表示落下强度。阐述了试验设备和样品处理方法,讨论了试验参数的选择依据。结果表明:通过该方法测得萤石球团的落下强度稳定且数据可靠。

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.
