The invention discloses a compact type coal powder distributor comprising a base and an annular coal powder distribution case fixed to the base. The base is fixed to an outlet of an externally-connected coal mill separator. An inlet of the base communicates with the outlet of the externally-connected coal mill separator. The annular coal powder distribution case is divided into a plurality of bin bodies. Bottom inlets of the bin bodies communicate with an outlet in the top of the base correspondingly. Top outlets of the bin bodies communicate with resistance adjusting cases and powder outlet pipes in sequence correspondingly. The distributor is compact in structure and small in occupied space, and the air amount and coal powder distribution deviation of a primary air pipe are small.
