Analysis of Power Draw in Ball Mills by the Discrete

Abstract Ball mills like other comminution devices consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a Ball mills normally operate with an approximate ball charge of 30 . Ball mills are characterized by their smaller (comparatively) diameter and longer length and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other.

May 22 2019 · The ball ratio is usually selected from 2 1 to 5 1. In some cases a large ball-to-batch ratio is used. For example a wet-milled titanium carbide-based carbide bar can be used for 6 1. Because the volume of the mixture is large at this time. It seems that using the ball to material volume ratio to indicate the amount of charge will be more mills with the rod mill and ball mill laboratory work indices. Note in Figure. 1 that the rod mill product slope is less than 0.5 due to an extra amount of nes present being fi fi ner than 650 μm.

Using the discrete-element method to investigate ball

Discrete-element method (DEM) modelling is a powerful tool for studying particulate systems within the mineral processing industry. DEM simulations were conducted to investigate the power draw load behaviour and impact energy profile of an experimental ball mill under different milling conditions. Jul 18 2016 · Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
