four simulation tasks, consisting of AG, SAG and ball mills are reported. The simulation of AG and SAG mills are completed in less than 8 hours. The ball mill simulation with million spheres is completed in 27 hours. In the near future, these compute times can be halved with the advances in graphic card hardware. KEYWORDS

The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process. Furthermore, by ...

The movement of the particulate materials in the ball mills is closely related to the rotational speed of the mill. With the increase of rotational speed of the mill, the movement of the particulate materials mainly undergoes slipping, cataracting and centrifuging [32], as shown in Fig. a ball mill, the grinding media (steel balls) are attached to the mill liner due to inertial and ...

A method for simulating the motion of balls in tumbling ball mill under wet condition is investigated. The simulation method is based on the threedimensional discrete element method (DEM) and takes into account the effects of the presence of suspension,, drag force and buoyancy. The impact energy on balls' collision, which enables us to provide useful information for predicting the ...

Gearboxes are frequently used in the mining industry, especially for power transmission between the electric drive and the ball mill; besides the extreme complexity of a ball mill gear transmission system, the fault diagnosis by vibration analysis can be easily distorted by the presence of impulsive noises due to the ball pulses on the mill shell. Although several works in the literature are ...

At Carajas, the new grinding plant was operational in 2002, with two ball mill lines followed by a desliming plant. The closed circuit, wet grinding mills were designed to operate at 600% circulating load, in order to minimize the production of fine particles and consequently give increased recovery at the desliming plant.
