The ball milling process is generally divided into two types, the dry ball milling process, and the wet ball milling process. This article takes dry ball milling as an example to introduce the ball milling process. First, select the appropriate size and weight of the grinding medium according to the particle size of the grinding material.
1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
Selection of ball mills is discussed in Highenergy and lowenergy ball millschapter. [1, ] Figure 2. Main factors that affect the endproduct and its properties during ball milling. [1, ] (Figure: Aki Saarnio). Shape of the milling vial Internal shape of the ball mill can be flatended or concaveended (roundended).
In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.
Every major party in Bihar has promised to reopen the mill in Motihari ahead of elections since 2005, when Nitish Kumar first made the promise as a prospective chief minister. Ten years later, in 2015, when he joined hands with his old foe Lalu Prasad Yadav ahead of the Bihar Assembly election, the subject was raised again.
