An improved method for grinding mill filling ScienceDirect
These scans are widely used as part of mill liner wear modelling and condition-monitoring programs; however, surface profiles and mill filling data can also be obtained at the same time (Toor et al., 2011). LiDAR scanning is probably the most accurate filling measurement method available but relies on specialised equipment not readily The selection function having a unit of min −1 can be used in the population model to the following form as proposed by Austin et al. (1984): S i = A x i 1000 α ∗ 1 1 + x i μ Λ, Λ ⩾ 0 where A, α, µ and Ʌ are model parameters. A has the unit of min −1 and varies with mill conditions. α and Ʌ are dimensionless, and their valueCalculating breakage parameters of a batch vertical stirred mill
