The first compartment of the open circuit mill contains balls ...

## amount of material present in kg at any instant in a close ...

The material retaintion time in a ball mill depends on the tons of ball and total material fed to the mill (fresh feed +separator’s rejects). It can be approximated using the following expression: T(minutes) = 6.7 x (F/P) Where: F = total tons of grinding bodies in the mill. P = Mill’s production (total dry feed material) (ton/hr) It is also possible to calculate the tons of resident ...

## Comminution testing to reduce risk | FLSmidth

The FLSmidth VXP10 vertical stirred mill offers ultra-fine grinding capabilities. A pendulum grinding test in this mill determines the residence time and energy input to achieve a specific size reduction, based on progressive sizing reduction as the material passes through the VXP10. Test results can then be used to determine the operating parameters for full-scale production mills. Keep ...

## A Review of the Modeling of High Pressure Grinding Rolls

Unlike in ball milling, the residence time for individual particles in the bed is the same in HPGR. All particles in the feed experience a fixed-time of residence (Fuerstenau et al., 1991). Even then, Gutsche and Fuerstenau (2004) showed that similar to ball mills, the self-similar behavior holds true for the product size distribution of the HPGR.
