PROBLEM TO BE SOLVED: To provide a dust scattering prevention cover for a crusher which has a simple structure and whose equipment cost is low.SOLUTION: The flow rate of dust intruding into a dust scattering prevention cover (dust flow rate reducing cover part) 32 and a dust scattering prevention cover (dust flow rate reducing cover part) 34 is reduced. As a result, the residence time of the dust in the dust scattering prevention cover (dust flow rate reducing cover part) 32 and the dust scattering prevention cover (dust flow rate reducing cover part) 34 becomes long and then the dust is easily settled on a conveyor 2.SELECTED DRAWING: Figure 1 |
