The invention relates to the technical field of dust treatment, and discloses a process for dust removal and recycling of a steel mill. The process comprises the following steps: step 1, collecting all kinds of dedusting ash which is difficult to sinter and burdening in the steel mill into an elevated powder bin by adopting pneumatic conveying; step 2, adding sintering fuel into a sintering fuel four-roll crusher to be crushed, and independently loading the fuel into a bin for standby application; step 3, designing a drum-type cylinder sealing mixer according to the dust discharge amount of the steel mill, wherein the drum-type cylinder sealing mixer is provided with five charging ports; step 4, adding materials into the drum-type cylinder sealing mixer through all connectors, and then starting the drum-type cylinder sealing mixer to start mixing; and step 5, after material mixing is completed, guiding the mixed materials into a material mixing bin, and then detecting the moisture content condition of the mix
