However, at present there is a gradual shift from use of ball mill to use of vertical roller mill (VRM) for clinker grinding. This change, from largely used ball mills towards vertical roller mills is mainly due to certain advantages offered by VRMs over ball mills such as: drying, grinding and classification operations carried out in a single ...

the apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where .

Selective comminution using a pin mill, at a circumferential speed of 20 m/s, yielded a recovery of 96.5% of REE minerals and allowed rejection of 27% of barren material. This shows that both selective comminution and sensor-based sorting can be considered as complementary beneficiation steps when processing these REE ores.

The Vertical Roller Mill (VRM) is comparatively more energy efficient than ball mill 21 consuming only 65% of the energy consumption of the ball mill. The ball mill along with a pre-grinding system such as roll press is also used in some of the plants with very hard and abrasive limestone. Pyro-processing This takes place in the kiln system.

The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical roller mills (VRM) have a higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement.

One of the most important aspects of underground hard rock mining is ventilation.Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity (e.g., silica dust, NOx), diesel equipment (e.g., diesel particulate, carbon monoxide), or to protect against gases that are naturally emanating from the rock (e.g., radon gas).

2.2. Mining and blasting. A great number of studies on optimum fragmentation, so-called Mine-to-mill, have been carried out around the world. Since the 1970 s, it has been recognised that rock fragmentation by blasting affects secondary fragmentation, loading, hauling, crushing and grinding ( Zeggeren & Chung 1975 ).
