1 干法生产工艺的特点1.1 节约用水干法制砂用水量很少,除喷雾降尘外,基本不用水。一般每生产1m~3砂石用水100L左右,只是湿法生产的1/20。1.2 两段制砂,简化工艺人工骨料系统一般分为粗碎(进料粒径为1500~350mm,出料粒径为300~100mm);中碎(进料粒径为300~100mm,出料粒径为100~30mm);细碎(进料粒径为100~30mm,出料粒径为25~3mm)以及磨碎等。
A dry process of the characteristics of 1.1 water conservation Sand dry water is very small, in addition to spray dust, the basic need for water. General production of 1m ~ 3 gravel water 100L or so, but wet production of 1 / 20.1.2 two sand, simplified process Artificial aggregate system is generally divided into coarse crushing (feed particle size of 1500 ~ 350mm, the material The size of 300 ~ 100mm); broken (feed size of 300 ~ 100mm, out of the particle size of 100 ~ 30mm); crushed (feed particle size of 100 ~ 30mm, the particle size of 25 ~ 3mm) And grinding and so on.
