粉尘是一种主要的大气污染物,影响作业环境,对呼吸系统和眼睛等的危害很大。粉尘通常是由于物料的破碎、筛分、输送和堆存等而产生的1～200μm左右的微粒。就板石矿业公司选矿厂而言,中细碎破碎、振动筛筛分和胶带的转载过程均能产生粉尘,这类粉尘微粒都有一个共性,即均是原固体物的变细,其化学成分并未改变。由于板石矿矿石属鞍
Dust is a major atmospheric pollutant, affecting the working environment and damaging the respiratory system and eyes. Dust is usually due to the material crushing, screening, transportation and storage and the like generated about 1 ~ 200μm particles. In the case of the Slate Mining Company beneficiation plant, the medium finely crushed, the sieve shaker and the reloading process of the tape can produce dust. These dust particles all have one commonality, that is, the thinning of the original solid, the chemical composition Has not changed. Because the slate ore is a saddle
