PROBLEM TO BE SOLVED: To provide an operation method for a vertical crusher suitable for minutely crushing a slag.SOLUTION: An operation method includes crushing a slag using a vertical crusher for crushing using a crushing roller, a raw material charged on a rotary table after consolidating using an auxiliary roller. The biting rate for the raw material is made to be ≤6.5 m/s by controlling the rotation speed of the rotary table. According to the operation method even when crushing the slag, the crusher prevents abnormal vibration caused by the slip of the crushing roller on a raw material layer, thereby crushing the raw material efficiently. |
