    Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density; Work Index

    The wear factor can be manipulated to calculate the often more convenient and more physically direct specific wear rate (also known as a dimensional wear rate ), k, commonly measured in units of mm3/Nm . The specific wear rate is simply the wear volume divided by the product of the normal load and the sliding distance, d, as shown:
