Abstract: -Based on the research on the grinding media motion in the ball mill, the discrete equation of grinding media motion about ball mill is established and the motion regimes of grinding media is simulated using the discrete element method (DEM) with simplifying the contact model of grinding media and rock material.
For the DEM s etup of the ball charge, the mill chamber is initially filled with a 34% volumetric fill of ball sizes ranging from 32 – 65 mm. The full ball size d istribution is given in Table 3.

This approach has the added advantage in that different particle sizes can be effectively milled in a ball mill because each media size can effectively break a particular particle size during the size reduction process ensuring that the product fineness is optimized. The same policy is employed for the make-up charge where adding different ball ...
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.
Mar 18, 2018· Ball Mill The rotation of the Ball mill causes the charge consisting of grinding media (steel balls) and feed material to be lifted due to centrifugal forces and friction between the media and the lining. The height to which the charge is lifted d...

The second chamber is the fine grinding chamber. It is lined with classifying-type mill shell liners and provided with finer ball charge. Classifying liners ensure that the ball charge is segregated along the length of the chamber keeping larger grinding media at the beginning of the compartment and smaller media towards the end of the chamber.
Mar 10, 2011· Re: How Can I calculate new ball size and weight desing for ball mill. Hi, We have a similar mill. Pregrinding with hammer crusher and mono-chamber mill. Thisis what a proposed based on literture review i did and others agree its more and less correct. But remember it all depends on your mill feed size after pregrinding.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The Selection and Design of Mill Liners . Malcolm Powell*, ... The second primary function of a liner is to transfer rotary motion of the mill to the grinding media and charge. After all, it is the interface between the mill and the grinding charge. ... High–low double wave ball mill liners – These are a refinement of the wave liner, Figure 5.
Jan 27, 2020· Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% - 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill's contents. SAG mills generate higher levels of impact reduction and ...

Reducing the ball charge will reduce the grinding capacity, and the comment on installing a grate discharge is a good one as it will let ore out sooner, thus minimizing overgrinding, which will occur if the mill is (temporally) too big, or one chamber is too big in a multi chamber mill.
Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter). Ball diameter here is in the range 60-80 mm. In a two-chamber mill, the media in the second chamber are typically in the range 15-40 mm, although media down to 5 mm are sometimes encountered.
Re: Mono-Chamber Ball Mill. Hi Raj, Thanks for your reply. There is a hammer crusher before the raw mill so mill feed is very fine with d80 (80% passing size) of 4000 micron and 1% passing 3/8 mesh (9.5 mm sieve). Based on Bonds formula I calculated the max ball size to be 50 mm.
In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.
