What Are The Reasons for The Large Vibration
When reaching a certain speed, the vibration of the crusher will become more intense, and even may cause the hammer crusher to lose balance.The bearing clearance exceeds the limit or has been damaged. To solve these problems, we usually replace the bearing with a new one. 7.The hammer head of crusher is of poor quality.
