ing volume in a ball mill, at J = 20 %, and found that the maximum normal breakage rate occurred at an interstitial filling U of approximately 0.4. A more recent study by Fortsch D.S. (2006) showed that the reduction of J leads to an increase in capital and installation costs of the mill-ing equipment. He proposed J = 35 % as optimal ball fill-
method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 40-10 mm. The mill speed varies from 12 to 30 rpm. Planetary mill: High energy mill widely used for producing metal, alloy, and composite powders. Fluid energy grinding or Jet milling:
Jan 01, 1998· Mechanical disintegration of excess sludge Parameter-studies have been carried out using a stirred ball mill, a high-pressure homogenizer, an ultrasonic homogenizer and a shear-gap homogenizer. The performance of the various disintegration methods can be compared with each other using the specific energy, which is defined as the amount of ...
Jun 03, 2021· 10%· Abstract The stirred ball mill (SBM) method is a common method applied in large-scale sludge disintegration. Many reports focus on the disintegration results of sludge or the influence of parameters on the anaerobic process of treated sludge, but there have been few studies on the mechanism of sludge disintegration by SBM. This study focused on the mechanism of sludge disintegration …
An optimum of the bead diameter and the stress intensity in stirred ball mills could be detected. A comparison of the results of different methods of sludge disintegration shows that the investigated ultrasonic homogenizers are inferior to a high pressure homogenizer and a stirred ball mill in terms of energy consumption.
