PROBLEM TO BE SOLVED: To enhance durability of an exhauster, and the like, and to prolong the service life while enhancing energy efficiency even at the time of pulverizing a highly abrasive object. SOLUTION: This pulverizing system is provided with a pulverizer 3 which pulverizes the fed object, a classifier 5 which classifies the pulverized material pulverized by the pulverizer 3, a first exhauster 17 which sucks the first dust- contg. air from the classifier 5 and a first dust collector 18 which separates and takes out the pulverized material from the first dust-contg. air on the upstream side of the first exhauster 17. Further, the pulverizing system is provided with a second exhauster 19 which sucks the second dust-contg. air from the pulverizer 3, a second dust collector 20 which separates and takes out the pulverized material from the second dust-contg. air on the upstream side of the second exhauster 19 and an air blowing path 23 through which the air from which the pulverized material is separated in the second dust collector 20 is fed into the classifier 5.
