Slurry conveying system

The invention relates to a slurry conveying system. The slurry conveying system comprises a slurry conveying pipeline and a magnetic sleeve which sleeves the outer side of the slurry conveying pipeline; multiple magnetic balls are arranged in the slurry conveying pipeline; slurry absorption passages are arranged in the magnetic balls; an electromagnetic driving device which reacts mutually with the magnetic balls so that the magnetic balls can be distributed along the length direction of the slurry conveying pipeline is arranged below the magnetic sleeve; and the magnetic balls can be uniformly distributed along the inner side wall of the slurry conveying pipeline under the effect of the magnetic sleeve. The slurry conveying system provided by the invention has the advantages that the inner wall of the pipeline is insulated from slurry by the magnetic balls, so that the slurry is not adhered to the inner wall of the pipeline; the loss caused by the fact that the slurry is adhered to the inner wall of the pipe
