Rapid homogenization method of Portland cement dry powder

The invention provides a rapid homogenization method of Portland cement dry powder, and relates to the technical field of cement production. The method comprises the following steps of crushing a Portland cement clinker, gypsum, a granulated blast furnace slag, limestone, kiln ash, zeolite and a grinding aid into a diameter less than or equal to 40mm; evenly mixing the Portland cement clinker, thegypsum, the granulated blast furnace slag, the limestone, the kiln ash, the zeolite and the grinding aid in proportion, then feeding into a drying and power-grinding system for power-grinding, controlling the moisture content of a finished product to be less than and equal to 1.3wt%, controlling a sieve residue of 80 micrometre sieve to be less than and equal to 14wt %, and obtaining a dry powdery raw material; putting the dry powdery raw material into a mixing tank of an intermittent batch raw material homogenization system to make the whole raw material be thoroughly mixed, and finally making the composition unifor
