Accepted manuscript 2 The effect of ball size distribution on power draw, charge motion and breakage mechanism of tumbling ball mill by discrete element method (DEM) simulation
A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances. The energy balance relies on temperature and mass flow data. The key model parameters to be measured are mill temperature in the feed and discharge streams, mill power draw and the mass flow rate in the feed stream.
Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying

When the planetary mill is scaled-up in geometrical similarity, the impact energy of the balls is proportional to 4.87 power of the scale-up ratio. AB - The objective of this paper is to investigate the scale-up method of the planetary ball mill by the computational simulation based on Discrete Element Method.
2.1 Experiment. A pilot scale ball mill was designed as shown in Fig. 1.Its geometry information is listed in Table 1.We carried out a detailed study on the effect of liner profile and assembled angle on the grinding kinetics by conducting experiments with three types of RPASLs (Quadrilateral ASL, Pentagonal ASL, and Hexagonal ASL) and three assembled …

Kano et al.8) found that it was the impact ener-gy of the balls that has a large effect on the grinding. Rocking mills (ball mills where the pot is rocked
Hammer mills. These mills, which were original driven by water wheels, but later also by steam power, became increasingly common as tools became heavier over time and therefore more difficult to manufacture by hand.. The hammer mills smelted iron ore using charcoal in so-called bloomeries (Georgius Agricola 1556, Rennherden, Rennfeuer or Rennofen: from Rinnen = …
For rod, ball, or pebble mills the peak is usually near Vp = .50, while actual observations as low as V= .42 have bean made in some ball mills (Rowland, 1973). See Figure 2. Power draw is not significantly affected by the presence of the slurry in the mill.

Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in …

In this research, the effect of ball size distribution on the mill power draw, charge motion regime and breakage mechanism in a laboratory ball mill was studied using the discrete element method (DEM) simulation. The mill shell and crushing balls were made of Plexiglas® and compressed glass, respectively. Modeling was performed using Particle Flow Code 3D (PFC3D).
Mishra and Rajamani [ 3] [ 4] were introduced DEM method to simulate the motion of balls charge in the tumbling mills. After that, Cleary [ 5] studied the charge motion, segregation, wear, and power draw in a ball mills through DEM simulation. Several studies have been reported on modelling of mills by DEM simulations.
