根据李楼铁矿1~#、2~#破碎站所属硐室的实际布置方式,运用数值模拟对实际风流规律进行模拟分析,得出冲击风流随风筒压入破碎硐室内后速度略有增加,随后降低,在硐室空间内形成涡流。涡流内风速较小,保持在0.25 m/s以下。
According to the actual arrangements of the chambers of 1 ~ # and 2 ~ # crushing stations in LiLou Iron Mine, numerical simulation was used to simulate the actual wind flow law, and the result showed that the velocity of impact wind flow slightly increased , Then decreased to create eddy currents in the chamber space. Turbine wind speed smaller, maintained at 0.25 m / s or less.
