摘要
针对某钢铁公司露天原料场的四种矿料 ,首先进行筛分实验 ,确定出颗粒的细分 ;并在风洞中测定了各物料不同颗粒下的起动风速值以及扬尘量随风速的变化关系。
Screening test on 4 kinds of ores in the open-air raw material yard of an Iron & Steel Company is carried out first to determine the composition of each kind of particle.The threshold velocities of particles and the alternation of blown-up dust against the wind velocity are then measured in wind tunnel.
