The ball milling toughness of WFA grain (White fused alumina) generally does not have a fixed range. It depends on the purity, crystal structure, particle size, and manufacturing process. According to the requirements of GB/T 23538-2023, the ball milling toughness test method of WFA grain is ball milling toughness test. The abrasive wear rate caused by the rotation of a steel ball over a certain period of time is used as the criterion.
