Analytical methods to describe the degree of celldisruption had to be developed. The best results were obtained using a stirred ball mill and a highpressure homogenizer. As a result of disintegration the degradation is accelerated and the digestion time can be reduced, especially when using immobilized microorganisms.

Mechanism Study of Excess Sludge Disintegration by Stirred Ball Mill. Stirred ball mill(SBM) method is one of the usually method which applied in large scale application cases of sludge disintegration This study focuses on investigation the mechanism of sludge disintegration by SBM method Besides analysis.
Mechanical cell disintegration and its influence on anaerobic digestion was investigated using four different methods. Methods to describe the degree of celldisruption were developed and the release of organic components into the sludge water was measured. The best results were optained using a stirred ball mill and a highpressure homogenizer.

Ultrafine Grinding in a Tower Mill. The Tower Mill is a vertical "stirred" ball/pebble mill recently introduced in the Western Hemisphere. This device offers a significant power savings on wet fine grinding applications when compared to conventional tumbling mills.
Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

Microbial growth reduction in sewage sludge by stirred ball mill ... Dec 11, 2007 ... Treatment and disposal of sewage sludge from wastewater treatment plants accounts for about half or even up to 60% of the total operating cost. ... microbes through mechanical energy inputs by means of stirred ball milling.
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.

The stirred milling technologies can be divided into two subcategories: gravityinduced stirred mills and fluidized stirred mills. Gravityinduced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidized stirred mills use a rotational movement to fluidize a ...
Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between mm and mm in diameter.
