Ball Mill Design Parameters. Size rated as diameter x length. Feed System. One hopper feed; Diameter 40 – 100 cm at 30° to 60° Top of feed hopper at least 1.5 meter above the center line of the mill.
Optimization of processing parameters of a ball …
The aim of this work was to optimize the ball mill based refining process of chocolate, in terms of refining time and energy consumption. Experiments were planned following a central composite design (CCD), considering refining time (rt) and agitator shaft speed (as) as factors.
Design parameters for a ball mill - …
he design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material feeders, and the system for discharging the output product The size of a mill is usually characterized by the Quantitative estimations of these parameters can be found in [4, 5, 23]
Assessing the dependency of selection function …
And as summarised in Table 5, the selection function parameters a k and μ k are strongly dependent on ball size and mill diameter while parameters α and Λ are constant throughout. The breakage function parameters (β, γ, and Φ), in contrast, are all notably unaffected by the experimental conditions and the design of the ball mill.
CALCULATION OF THE POWER DRAW OF DRY …
To verify the new power draw approach, detailed surveys of the 14 ball mill circuits at 6 different plants were carried out. The ball mills sampled in this study are ranging in diameters from 3.2 m to 4.8 m. Design and operational parameters of the ball mills sampled are given in Table 1. Table 1.

Ball Mills - Mineral Processing & Metallurgy
Working Principle & Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ...

In order to avoid over crushing, the client selected Xinhai wet type grid ball mill in grinding process. The grinding medium are steel ball and ore itself, the grinding efficiency is high, it also adopts the hydrostatic and hydrodynamic bearings, which ensures the smooth operation and easy to grinding.
Optimization of mill performance by using
operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree.
