The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill size.In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables. Mill Speed is one variable that can often be easily changed with a variable frequency.

Determination the grinding balls bulk weigh directly operating in a ball mill becomes necessary on practice. It is done in order to accurately definition the grinding ball mass during measuring in a ball mill and exclude the mill overloading with grinding balls possibility.Then, based on the improved evidence combination method, an improved multi-classifier ensemble modelling is proposed in this paper, which is applied to the soft measurement of ball mill load. Experiments are performed with a laboratory ball mill, and the vibration signals of bearing seats are used as auxiliary variables for the mill load.
Read MoreLoad percentage calculation that belongs to mill diameter (𝐷𝑚) and distance between top point in the mill and load surface (H) [5-7]. This equation is profitable for determining of whole mill load volume which is included stony and metallic balls. Mill load ( ) = 113.7 - 127.3 H . .The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact.
