### Discrete element simulation of particle motion in ball

Ball mill is a 12 type of rotating drum, mainly used for grinding and the particle motion in a ball mill is a major factor affecting its final 13 product. However, understanding of particle motion in ball mills based on the present measurement techniques is still 14 limited due to the very large scale and complexity of the particle system

### Modeling of the planetary ball-milling process: The case

8/1/2016· 2.2. Contact modeling. The most critical ingredient in the model of a ball mill is the contact law. Contact models belong either to the (i) discrete or (ii) continuous approach .While (i) is based on momentum balances, in (ii) a force–displacement law is added to the equation of motion, as a combination of a spring in parallel with a damper, causing energy dissipation, plus a friction element.

### Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

### Discrete element simulation of particle motion in ball

7/15/2018· Discrete element (DE) simulation of a ball mill with a large number of particles is challenging when each particle is considered. Similarity principle could be adopted to reduce the number of particles in a simulation whilst still maintaining the accurate flow behaviour of particles.
