A method for improving the fluidity of sludge blending in power plants, characterized by: including the blending and transporting device as claimed in claim 1, and the method includes: After storing the sludge in the dry coal shed, use an excavator to mix the gravel coal and sludge at a ratio of 1:1; Dig a bucket of sludge, dig a bucket of gravel and coal to mix, and then push the coal and repeatedly turn it over to ensure even mixing, then place the gravel, sludge and coal in the accessible area of the bucket wheel machine; When loading into the warehouse, the coal and sludge gravel are mixed at a ratio of 9:1 through 2 bucket wheel machines. The coal is 9:1 and the sludge gravel coal is 1. The material is taken to the belt. The bucket wheel machine that takes out the coal is controlled at 800 tons. / hour, the bucket wheel machine that takes out gravel, sludge and coal is 80 tons / hour; The two coal types are finally merged on one belt by the belts of two bucket wheel machines and mixed again, and then passed through the roller screen and coal crusher for full mixing before being sent to the raw coal bunker.
