Prediction of slurry grinding due to media and

01/12/2020 Semi-autogenous (SAG) mills are a broadly used class of machine for large scale grinding of rocks in mineral processing. Although geometrically simple they display a broad range of dynamics with complex interactions that make their selection, design, operation and scale-up difficult. The most commonly used model are simplified process models, usually formulated as population balances and

Effect of the operating parameter and grinding

15/12/2019 The experimental results showed that the Abbott-Firestone curve can evaluate the lifter surface topography. The wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size. Increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear rate.

Autogenous and Semi-Autogenous Mills FLSmidth

SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your operation.
