Frictionreduction ratiois 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 empiricalformulato calculate the frictionreduction ratioof HPG fracturing fluid (Lord, 1987):

In Grinding, selecting (calculate) the correct or optimumballsize that allows for the best and optimum/ideal or target grind size to be achieved by yourball millis an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, theballused inball millsis oversize “just in case”. Well, this safety factor can cost you much in recovery and/ormillliner wear and ...

The true density of balls are around 7.5. Then, the optimal mass ratio of ball to powder in ball mill is 7.5*24/ (2.5*17.6)= 4.09 to 7.5*21/ (2.5*11.2) = 5.63.

Sep 01, 2013· As the sizereduction ratioincreases, the optimumball ratiomoves towards more small balls. At the finest grinding with a sizereduction ratioof 128:1 (Fig. 7d), a 50.8 mm/25.4 mmballmix at a 13:87ratiowas found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.
