View AllGrinding slurries are known to be nonnewtonian. for such suspensions, slurry viscosity is not a constant, but is a function of shear rate. this study was aimed at the derivation of an estimate of a typical shear rate range inside a ball mill, in order to determine appropriate values of apparent viscosity for studies of the effects of rheology on grinding.
View All2019910in solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.as the speed of rotation approaches the objects natural frequency, the object begins to resonate, which dramatically increases system vibration.
View All201999the critical speed rpm is given by n c 42.29 d, where d is the internal diameter in metres. ball mills are normally operated at around 75 of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. the mill is usually divided into at least two chambers although this depends upon feed input size mills including ...
