Sludge drying equipment

The utility model relates to the technical field of sludge drying, and discloses sludge drying equipment which comprises a sludge drying machine main body and an inlet pipeline, a feed hopper is arranged above the inlet pipeline, a crushing box is arranged below the feed hopper, the feed hopper is communicated with the crushing box, a crusher is arranged in the crushing box, a flow limiting box is arranged below the crushing box, and the flow limiting box is communicated with the crushing box. The flow limiting box is communicated with the inlet pipeline; through cooperative use of a driving motor, a flow-limiting rotating shaft, a flow-limiting rotating wheel, a driving assembly, a crusher and the like, when sludge flowing in from a feeding hopper is crushed, massive sludge falling from the feeding hopper is crushed through the rotating crusher, flows into a strip-shaped groove in the flow-limiting rotating wheel through a material storage box, and then is crushed through rotation of the flow-limiting rotati
