Grinding technology

The use of INDEX grinding tool holders provides optimal conditions for reliable complete machining of your workpieces. This reduces throughput times and you do not need a grinding machine. And not only that – to increase efficiency, many grinding cycles for OD, face, slot and flat grinding are already included in the control upon delivery of the machine.

Energy Use of Fine Grinding in Mineral Processing | …

 · Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget. Overall energy use and ...

Quantifying the energy efficiency of fine grinding circuits …

Size Specific Energy (SSE) differs by relating the grinding energy to the quantity of new fines generated. For typical circuits that involve AG/SAG, HPGR or ball milling, the generation of -75 µm material (denoted as SSE75) is a suitable marker size with which to benchmark performance because it contains 80% of the surface area generation 1 and energy is proportional to surface area ...
