[0003] In the prior art, after the centrifugal ore dressing machine screens the ore particle groups in the pulp, since the ore particles are immersed in the pulp, in order to facilitate the transportation and storage of the ore particles, the screened ore particles need to be dried. However, if too many ore particles are fed into the dryer at one time, it is easy to cause insufficient drying of the surface of the ore particles, and secondary drying is required, which affects the working efficiency. Moreover, too much falling is likely to cause blockage of the feed bin. Therefore, a rapid drying device for a centrifugal ore dressing sieve is needed. Summary of the Utility Model
