Fault 2: Mining ball mill reducer bearing heats up. Reason: One of the possible reasons for the ball mill reducer bearing heating is insufficient lubrication. Insufficient lubrication can cause bearings to operate at high temperatures, resulting in overheating. Another cause could be excessive load or improper installation.

This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.

Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.
