Effects of Coal Rock Characteristics,Haulage Speed and Rotational Speed on the Wear of Drum Blades of Coal Mining Machine
Coal mining machine is an important equipment for cutting and loading coal,which has an important influence on improving the automation level of coal mines.The roller blades produce certain wear in the process of coal loading,and the wear effect of different factors on the blades is analysed in the form of discrete element simulation.A model for drum cut-off analysis is established,and the influence of coal rock solidity coefficient,hauling speed and drum rotational speed is analysed to provide a reference for the selection of the working parameters of the coal mining machine.
