SLAG CRUSHING APPARATUS FOR POWER PLANT BOILER DRY SLAG

摘要

A slag crushing apparatus for power plant boiler dry slag, comprising a rack (4) and a crushing bin driven by a motor, wherein the crushing bin comprises a coarse crushing bin (3) and a fine crushing bin (10); a feeding hopper (2) is provided on an upper portion of the coarse crushing bin (3); dry slag enters the coarse crushing bin (3) from the feeding hopper (2); a coarse filter screen (19) is mounted at a joint of the coarse crushing bin (3) and the fine crushing bin (10); a discharging hopper (11) is provided at the bottom of the fine crushing bin (10); the fine crushing bin (10) is communicated with the discharging hopper (11), and a fine filter screen (20) is further provided between the fine crushing bin (10) and the discharging hopper (11). The dry slag enters the coarse crushing bin (3) from the feeding hopper (2) to be subjected to first-stage crushing firstly; slag powder having a large particle size is formed after primary crushing; the slag powder enters the fine crushing bin after being filtered by the coarse filter screen (19) to be subjected to second-stage crushing, then slag powder having a smaller particle size is formed; and finally the slag powder is discharged from the discharging hopper (11) after being filtered by the fine filter screen (20).
