  • Study of limestone particle impact attrition - ScienceDirect

    2007-2-1 · The effect of limestone impact attrition cycles was first investigated at 25 C and 1 atm pressure. The conveying gas velocity in the particle acceleration tube was 55 m/s, resulting in particle velocity on impact for original particles (harmonic mean diameter of 689 μ m) of 23.7 m/s. The decrease in particle diameter due to impact attritions increased the particle impact velocity for subsequent cycles.
