ball mill grindability. The test mesh used was 100 mesh P gt; 1416 ]. The Bond work index W i was calculated from Equation (2) W i = /(P 1) X (Gbp) [10/(P 80) 0,5 #177; 10/(F 80) ] (2) Where: F 80 is the size in (#181;m), at which 80 percent of the new feed to ball mill passes,

Mill diameter; Mineral density; Work Index. Bond estimated the amount of wear in terms of kilograms per kWh based on the abrasion index, A;,, Wet Ball Mill = kg kWh = (A ) ; Dry Ball Mill = kg / kWh = i ; Replacement Ball Size
Work Index Know More ''Work Index'' is to measuring energy in size reduction what the ''meter'' is to measuring It starts with Bond''s Work Index equation: For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means...
Sizing Of Ball Mill Based On Grindability. 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. Live Chat; Jktech Laboratory Services
The mill power is measured by an electric system based on the torsion of the axis and depends on the rota tion frequency. For each batch test i the mill is loaded with a feed mass m = 1 kg and rotates for a time ti. At the end the energy Ei(Joules) is recorded and
19/10/2017#0183;#32;It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below: B the grinding balls diameter, mm; A the correction factor (for grinding balls A = 20,17; for cilpence A = 18,15);
In order to perform the Bond Index Test successfully it is necessary to use precrushed sample material as defined below: Module Ball Mill. Minerals precrushed to lt; mm and sieved ; Drillcore precrushed to lt; mm and sieved ; Half Drillcore precrushed to lt; mm and sieved ; The Bond Index conforming ball charge consists of: 43 x balls
Ball Mill Design/Power Calculation. #183; 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 andget price
The test determines the Bond Ball Mill Work Index which is used with Bonds Third Theory of Comminution to calculate net power requirements*. Various correction factors may have to be applied. W = Wi (10/P 10/F) Where W = Net power consumption in kWh/t Wi = Bond work index
