MoreFriction reduction ratio is the function of the average velocity of fracturing fluid, the gelled agent concentration, and the proppant concentration. Based on the linear regression of 1049 experimental and field data, Lord et al. put forward the following empirical formula to calculate the friction reduction ratio of HPG fracturing fluid (Lord, 1987):

MoreAt low speeds the ball rolled over each other and attrition takes place. 1,2 At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that break contact with the wall and fall to the bottom to be picked up. In this manner impact stress will also be induced and the size reduction made effective.

MoreReduction ratio = 2 – 20 depending on material. Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% – 65% range. Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = 6.25 tons/m3. In wet grinding, the solids concentration 1s typically 60% – 75% by mass.

MoreFrom the ball mill feed size distribution calculate the %+75 μ as: 100 – 19.3 = 80.7% +75 μ. 2. From the ball mill discharge size distribution calculate the %+75 μ as: 100 – 26.5% = 73.5% +75 μ. 3. Calculate the CSE as the average: (80.7 + 73.5) ÷ 2 = 77.1% + 75 μ. In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that 77.1 ...

More2013-09-01 As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a 50.8 mm/25.4 mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.
