Size Reduction by Grinding as an Important Stage in Recycling

Dec 18, 2013· Therefore, 6 to 20 pct of the energy use in fine grinding using ceramic media can be represented by "contained energy" in the grinding media itself. Sand media have much lower contained energy than ceramic media as the media must simply be mined or quarried rather than manufactured. Hammond and Jones report a contained energy of 0.1 MJ/kg.

Sep 01, 2020· When the grinding speed is increased from 30 to 80 m/s, the specific grinding energy dramatically decreases by 20.8 % from 120 to 95 J/mm 3. Beyond a grinding speed of 80 m/s, the specific grinding energy remains nearly stable. A grinding speed above 80 m/s is thus recommended for high-efficiency deep grinding of DZ125 superalloy.

Chapter 7 Energy Use in the Copper Industry

Both lower speed and shorter grinding times give better energy efficiency. Energy efficiency as a function of the number of revolutions (Nt) is shown in Fig. 6 and a rough correlation is that energy efficiency is propor-tional to the number of revolutions to -0.57 power. Fig. 7 shows the results of grinding limestone with initial
