Tumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials. They have been used for decades in the production of fines and in the final stages of ore comminution, where optimal levels for the enrichment particles’ sizes are obtained. Even though these ubiquitous machines of relatively simple construction have been subjected to extensive
Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. .
Alternatively, ball mills are closed systems and do not offer these advantages. Nevertheless, ball mills can be a more appropriate choice for grinding larger sized material starting at 1/4 " or larger. It should be noted that ball mills are much larger than Attritors and therefore require a special foundation.
Wet Ball Mill 100 – 20000 litres. Ball mills ( wet or dry processes) for intermittent grinding of hard materials and batches in different branches of the ceramic and chemical industry. To ensure iron-free grinding these mills are lined with steatite, Al2O3 or Polyurethane.
Estimation of Specific Rate of Grinding to Optimize the
Grinding forms one of the major unit operations in various industries such as pharmaceutical, cement, ceramics, mineral processing and beneficiation . Ball mills are widely used and less carefully studied. It has been observed that in most cases these ball mills are operated inefficiently and much of the energy is lost.
Advances in Discrete Element Method Application to
model to ball mill grinding. However, the same models could not be extended to semi autogenous grinding. Simply carrying out pilot scale SAG grinding is a very tedious task. At this time, the discrete element method appeared on the scene. DEM helps in simulating a number of features of SAG mills and AG mills, not to mention balls mill as well.
