 · Sir, Can you share the grinding balls standard surface area to be kept in raw mill and coal mill (monochamber)? Reply. 81 posts. Time Posted 25/01/2017 10:00:17. fjalali says. re Cement Mill Grinding Media. Dear Sagarhbt, Why are you concerned about surface area? I never hear about basing your ball charge on surface area! In your first compartment the grinding is not related to surface area .

Grinding is used in the finishing of connecting elements and is an essential component of machining technology. Here, the advantage is the high surface quality as well as the dimensional and shape accuracy, which is in the µm range. Depending on the area of appliion, cylindrical grinding, external grinding or internal grinding is used.

As the specific surface of a particle, the surface area per unit mass, is proportional to 1/L, eqn. () postulates that the energy required to reduce L for a mass of particles from 10 cm to 5 cm would be the same as that required to reduce, for example, the same mass of 5 mm particles down to mm. This is a very much smaller reduction, in terms of energy per unit mass for the smaller ...

The mm ball showed the lowest grinding efficiency, with a specific surface area of only m 2 /g even after 360 min of grinding. These results indie that the use of 1 mm and 2 mm balls in grinding talc could yield a larger specific surface area than the use of mm balls could. In planetary ball milling, the proper ball size could maximize the grinding efficiency with a balance of ...
