starting material can be loaded either through a spout feeder or by means of a single or double helical scoop feeder. Several types of ball mills are distinguished depending on the discharge system and these types are commonly known as overflow discharge mill, diaphragm or grate discharge mill and centreperiphery discharge mill, see [23].

A key component of the grinding process in a ball mill is the ball size distribution (BSD), which controls the grinding efficiency, product size distribution, and media wear rate. Higher rotational speeds and relatively small ball sizes produce finer BSDs, whereas lower speeds and significantly bigger balls produce coarser ones [ 71, 110, 148 ...

The balltopowder weight ratio was 10:1. The milling process was carried out at room temperature using highenergy ball mill (Laboratory Centrifuge Mill, P6, Germany). The ballmilling experiments were interrupted after selected milling times and a small amount of the powder was taken from the vial in the glove box.

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.

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.
