THE OPTIMAL BALL DIAMETER IN A MILL which can grind efficiently in a mill c is the exponent which characterizes the ball size distribution The condition for efficient grinding defined by Eq 7 will be fulfilled when the grain size distribution and the ball size distribution are the same which means that the parameters of both distributions are equal in Eqs 7 and 9 m c (10)

The law of ball size distribution in the horizontal planetary ball mill is studied by the discrete element method The results show that the maximum impact energy could be acquired when filling rate is 24% moreover the biggest mean contact force and the highest energy utilization ratio of balls could be acquired when the speed ratio is 1 5

This single unit is capable of milling materials up to a hardness of 10 Mohs and enables accurate and highly controllable particle sizes to be achieved typically with narrow size distribution A range of mill sizes is available for throughputs ranging typically from 0 5kg to 2 tonne per hour with average particle sizes as low as 1 to 2 microns

ball-mill ball mill size distribution calculator In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do

Acoustic estimation of the particle size distributions of sulphide ores in a laboratory ball mill by C Aldrich and D A Theron* Synopsis The acoustic signals emitted from a laboratory-scale ball mill were used for the estimation of the comminution of two complex sulphide ores viz Merensky and UG2 ores from the Bushveld Igneous Complex in

Vertimill has proven to be a versatile tool that exhibits many advantages over traditional ball milling in various applications It is capable of handling multiple feed sizes up to 6 mm and grinding to products less than 20 microns and has standard mill sizes ranging from 15HP (11kW) to 4500HP (3352 kW) Support from experts

10 02 2016Mill(300-350 – TPH) and before implementing the project we would like to gather as much information regarding the actual operation of this mill during cement grinding and the quality of the product in terms of the fineness/particle size distribution and how does it compare with the product of a ball mill relative to these parameters

14 05 2020The Bond equilibrium ball size distribution was used because the ball sampling campaign did not achieve the desired accuracy The test was performed with a 77 9% solid concentration 23 3% ball charge level and 75% of the critical speed Table 3 shows the parameters for the energy specific selection function determined in the torque mill tests

Oct 20 2008 The size distribution produced by the ball milling of various crystalline and non-crystalline materials showed that initially there was a fairly even distribution over the size range up to 355μm However as milling proceeded two distribution modes developed one at about 90μm (the persistent mode) and one at about 250μm (the transitory mode)

The energy specific selection function was determined in the torque mill operating under the same operational conditions except for the ball size distribution The Bond equilibrium ball size distribution was used because the ball sampling campaign did not achieve the desired accuracy The test was performed with a 77 9% solid concentration 23 3% ball charge level and 75% of the critical speed

1 27 for the rod mill and 0 67 for the ball mill The particle size distributions reported are shown in Figure 1 It follows that the No 1 rod mill/ball mill circuit was operating very efﬁ ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices
