THE OPTIMAL BALL DIAMETER IN A MILL

2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and The optimal ball diameter in a mill journalssystem,ABSTRACT. This paper covers theoretical and experimental explorations for the sake of determining the optimal ball charge in mills. In the first part of the paper, on the basis of Why use Different Size Balls in a Mill,In test 3, in which the grid was used to segregate the different sizes of balls, a further advantage of about 4 percent in efficiency is shown. The conical mill in

Ball mill;Ball size effects;Clinker;Grinding;Limestone: Issue Date: May2012: Abstract: Effect of ball diameter has been studied on the limestone and clinker samples under batch grinding conditions based on a kinetic model. Firstly, eight different monosize fractions between 1.7 mm and 0.106 mm formed by a 2 sieve series have A study on the effect of ball diameter on breakage ,because the number of balls in the mill increases as 1/d3. Thus, the rates of breakage of smaller sizes are higher for smaller ball diameters. The relation with T a and ball diameter in a 0.6 m diameter mill were given as aT α 1/d 9. This paper reports a study on the comparison of the breakage parameters of clinker and limestone under theThe optimal ball diameter in a mill journalssystem,ABSTRACT. This paper covers theoretical and experimental explorations for the sake of determining the optimal ball charge in mills.

Ball Mill Operating Speed msubbu.in · Calculations: The critical speed of ball mill is given by, n c = 1 2 π g R − r. where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.optimal ball size diameter for limestone ball mill,THE OPTIMAL BALL DIAMETER IN A MILL. 2010 2011 For each grain size there is an optimal ball size Trumic et al 2007 The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding In both cases the specific powerThe Optimal Ball Diameter In A Mill.A study on the effect of ball diameter on breakage ,because the number of balls in the mill increases as 1/d3.
