A quick check of the Rowland optimum feed size for this ball mill is between 3 and 4 mm; operating either circuit you describe will be at least 15% inefficient compared a more conventional ball mill feed size. The screen doesn't matter in terms of energy efficiency; only more crushing (or a small rod mill) that will improve the energy efficiency.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
For ball mill, Bond (1958) was proposing an empirical formula giving the top size of balls (make-up balls) DM function of the feed size xG (80% passing size - µm), the ore true specific gravity sg, the ore Bond Work Index Wi (kWh/st), the fraction of critical speed fc and the inside mill diameter D (m):
Aug 30, 2019· 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
[Feed size] <700mm [Output size] 10-80mm. Capacity 1-1120t/h. Output size 10-350mm. Capacity 1-95t/h. Input size <25mm. Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by ...

Prediction of the mill dimensions zThe ball-mill dimensions (internal mill diameter D and length L), for a given (L/D) ratio, for feed size D f and product size d (mm), for a known Bond work index w i (kWh/short ton) and for desirable capacity T (short ton/h), can be calculated from: D d T D D L f 3.5 )0.106 0.193 0.962 10.38 0.9180 ( ) (1 − × =
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's crushing ratio is smaller. The feed size is usually between 20-30mm and the product size is 0-3mm. Feed. Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate.

Ball Mill Feed Size. How Ball Mill Ore Feed Size Affects Tonnage Capacity, The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80 passing 10000 microns such feed causes power inefficiency if fed directly to a ball mill Ball Mill Feed Size
Jun 01, 2018· Fig. 5 shows the variation of size class 1 (M1) with the milling time for the two feed size distributions. For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate.
