Get Latest PriceA ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size
Mills with the rod mill and ball mill laboratory work indices note in figure 1 that the rod mill product slope is less than 05 due to an extra amount of nes present being ner than 650 m these nes proceed to the ball mill improving the ball mill ef ciency also the plotted rod mill p80 value as shown in figure 1 is 2900
Feb 15 2020 ball milling method improved the properties of bmsbiochar namely more efficient sh load a larger surface area more functional groups more negatively charged surface which resulted in higher removal efficiency of hg 2 and ch 3 hg 3201 mgg for hg 2 and 1049 mgg for ch 3 hg compared to the pristine biochar 1057 mgg for hg 2
There are six parallel conventional milling circuits at palabora mining company each milling circuit consists of a rod mill followed by a ball mill in series crusher product 9 mm is fed to the rod mill and the water is fed in ratio to the ore feed mass the rod mill discharge is pumped without any further water addition to the first
