Title: Pulverizing device
Inventor: TANAKA SHINSUKE
IPC: B02C21/00
Filed: 2000-05-29
Abstract: PROBLEM TO BE SOLVED: To efficiently and stably manufacture silica stone which is hardly pulverizable material for a long period of time with one pulverizing device. SOLUTION: This pulverizing device coarsely pulverizes the silica stone by using a vertical type pulverizing machine and further finely pulverizes part of the coarsely pulverized silica stone by a tube mill. The device described above has a classifying device which classifies the silica stone pulverized by the tube mill and separates fine powder. The fine powder is separated from the silica stone pulverized by the tube mill by the classifying device and the whole amount or a portion of the silica stone, which is pulverized by the tube mill and from which the fine powder is separated and removed, is pulverized again by the tube mill, by which the wear of parts generated in the vertical type pulverizing machine is suppressed. The silica stone which is the hardly pulverizable material is thus manufactured efficiently and stably for a long period of time by the one pulverizing device.
