Study on dust diffusion trajectory of unloading point in gantry crane area

In order to protect the port environment and effectively reduce the dust concentration at the unloading point the gantry crane area, this paper presents a summary of the dust diffusion rule under different working intensity, falling height, and ore moisture content. The simulation study was conducted to determine the dust diffusion path under different working intensity, falling height, and ore moisture content during ore loading and unloading at the port. The simulation study revealed that during the process of material falling, dust will continuously move in the fluid region. Furthermore, the collision between gravity, particles, and walls will exacerbate the migration range of dust. In the dust diffusion process, the small particle size is concentrated in the upper right corner of the funnel.
