Development of specific grinding energy model - ScienceDirect

Sep 01, 2012 · Abstract. Specific grinding energy is one of the most important performance parameter of the grinding process. Primary energy components of specific grinding energy are the major contributors to the total specific energy consumption in grinding. For high strength and hardness materials such as advanced ceramics, specific grinding energy requirement is extremely high which will eventually cause higher material removal cost of such materials.

Energy and temperature analysis in grinding

Creep grinding with a water-based emulsion at a workspeed of 0.005 m/s achieved a lower specific energy of 67 J/mm3 and a rather higher removal rate of 2.5 mm3/mm.s. As a consequence of the low specific energy and the high convection cooling, the maximum temperature measured was 40°C.

energy of crushed kernels (the sum of crushing energy and grinding energy) ranged from 47.6 to 100.5 kJ·kg−1 and from 44.6 to 85.3 kJ·kg−1 for hard and soft wheat, respectively. In addition, the other grinding energy indices confirmed that crushing of kernels prior to hammer mill grinding considerably reduced the grinding energy requirements.
