The utility model relates to a feed coal centralized pulverizing and conveying system which solves the problems that a single set of pulverized coal preparation system can only supply materials to a single gasification furnace and is poor in flexibility and high in investment. According to the technical scheme, the system comprises multiple sets of pulverized coal preparation systems arranged in an independent frame and multiple sets of pulverized coal conveying and distribution systems in one-to-one correspondence with the multiple sets of pulverized coal preparation systems, and every two sets of pulverized coal conveying and distribution systems form a group and share one pulverized coal pneumatic conveying pipeline to be connected with two to four pulverized coal storage bins; whereinthe pulverized coal preparation system comprises a raw coal bunker, a weighing coal feeder, a medium-speed coal mill and a pulverized coal collector which are sequentially connected, a pulverized coaloutlet of the pulverized coal collector is sequentially connected with a rotary feeder, a spiral conveyor and a pulverized coal fiber separator, and the pulverized coal conveying and distributing system comprises a pulverized coal buffer bunker and a sending tank which are connected with the pulverized coal fiber separator. The system is reasonable in design, high in equipment utilization rate, convenient for centralized operation and management, high in pulverized coal conveying and distribution flexibility and low in investment and operation cost.
