Abstract: According to the dust generation features of belt conveyor transfer point,a kind of conical hollow nozzle with low water pressure,less water and high atomization was designed which is suitable for the transfer point spraying dust-settling of belt conveyer.The atomization effect was verified in lab under the condition of low water pressure and less water.Through the on-site test and application with belt conveyor transfer point in No.1 mine of Shanxi Guoyang new energy company,the technology of spraying dust-settling with conical hollow nozzle can effectively solve the dust pollution of belt conveyor transshipment point.
