The invention discloses a limestone silo with a dust remover, which is good in use effect. The limestone silo comprises a silo body, wherein a limestone mixing tank is arranged at the lower part of the silo body; a filter deduster is connected at the upper part of the silo body; the filter deduster is communicated with a pipeline of which the tail end is connected with a gas powder diffuse; the gas powder diffuser is positioned in the limestone mixing tank; and the pipeline is further provided with a valve. The limestone silo with the dust remover disclosed by the invention removes a cloth bag, a keel and the like inside the original filter deduster and keeps the original casing. The upper part of the casing is welded with a DN200 pipeline which reaches the limestone mixing tank at the bottom of the silo, and the tail end of the pipeline is processed and produced with the gas powder diffuser; and when the silo is fed, the overflown limestone powder reaches at the gas powder diffuser through the pipeline and is diluted by water in the pool, so that the dust is no longer generated to avoid secondary pollution, and the use effect is good.
