ball milling reason

Sep 17, 2018 After the ball mill trunnion is finished, no obvious casting defects such as shrinkage, slag inclusion, segregation and cracking are allowed. These casting defects are often the main cause of the ball mill trunnion fracture. 2. The ball mill trunnion is generally a large steel casting part, some can reach more than ten tons.

  • Ball Mills an overview ScienceDirect Topics

    A ball mill is a type of grinder used to grind and blend bulk material into QDs/nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell. The nanostructure size can be varied by varying the number and size of balls, the material used for the balls, the material used for the surface of the cylinder, the rotation speed, and the choice of material to be milled.
