mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.
cement mill optimization. i have a polysius ball mill with capacity 110 tph. normally i get blaine at mill outlet around 200 while my product blaine target is 400 . separator reject baline is around 90 . i think i should put more smaller grinding media in ii chamber to increase the fineness at mill outlet to obtain 230 to 240 blaine.

Clinker grinding technology is the most energyintensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits significantly, the [.]
Available in diameters ranging from onesix inches, the Magotteaux Mining Grinding Media One Cast Forged is a good choice for customers in the cement, mining, and power station industries looking for an option for SAG mills, ball mills, or vertical tower mills applications. This is a costeffective alternative requiring a little upfront cost.
The flowsheet shows an example of a grinding circuit of a roller press with slab recirculation. The roller press takes over the role of the first chamber of a common ball mill grinding circuit.
HighChrome media has a superior performance and creates steady milling conditions due to its low wear rate. For each specific alloy there is a constant hardness of all grinding media. This creates a positive influence in the downstream process. highChrome media is suitable for both wet and dry ore applications in ball mills and tower mills.
This study considersclinker grinding in ball proposemore precise empirical equation for modified HGI relating withgrindability m, for broad based application for variety of minerals processing represented by HGI = 13 + 10 m (1) For clinker, it is HGI = 3050 and grindability values range
The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in realscale grinding plants. In fact, laboratorygrinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement ...

From 74% the media angle exponentially increases with pulp solid content. Unstable milling conditions starts to occur. The Sensomag® clearly detects the load expansion. (Figure 8.) This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate.
