01.06.2018· In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material. The experimental parameters that were kept constant in this investigation was the grinding media filling, powder filling and the mill

Wet ball mill is one of the most predominantly used method for the purpose of mixing and grinding of raw materials in laboratories and industry,, .The ball mill process is very complicated process governed by many parameters, such as ball size, ball shape, ball filling, slurry loading (with respect to ball amount), powder loading with respect to the amount of total slurry

Get PriceThe first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power

Get PriceEffect of Ball Diameter, The mill efficiency is then deduced by the division of the ordinate of curve Fig. 6.6b by that of Fig. 6.6c and the curve so obtained is plotted in Fig. 6.6d. From this graph it is seen that the mill efficiency is sensibly constant for fillings of up to about 50% and that for greater fillings the efficiency increases rapidly.Thus, it would appear that, for the

Get PriceBall size will also affect the grind P80. Efficiency is in part determined by the Axb value of the ore. A small lab mill can give guidance on the influence of ore strength and ball size. Larger balls will increase P80 in ball mill, thereby reducing overgrinding. If you believe the entry ball size sets the initial point on ball population and

Get PriceBall mill is the key equipment for grinding after the crush process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, and ball mill also can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

Get PriceGrinding elements in ball mills travel at different velocities. Therefore, collision force, direction, and kinetic energy between two or more elements vary greatly within the ball charge. Frictional wear or rubbing forces act on the particles as well as collision energy. These forces are derived from the rotational motion of the balls and the movement of particles within the mill and contact

Get PriceIt is well known that ball milling efficiency varies during the lifetime of the shell liner. For instance, the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to

Get PriceDry grinding experiments on cement clinker were carried out using a laboratory batch ball mill equipped with torque measurement. The specific energy was found to be dependent on operating parameters and clinker environment. Additional compounds such as gypsum and pozzolanic tuff improve energy efficiency. The optimal parameters allowing maximising the energy efficiency factor were determined
