rare earth elements conical ball mill

Feb 03, 2012· The nano-crystalline rare earth doped WC/Co powder with grain size of 8.45 nm was prepared by L. Sha et al[80] by high energy ball milling. The results showed that adding trace rare earth elements into carbides is effective to minimize the grain size of WC/Co powder.

Ball Mill an overview ScienceDirect Topics

Ball mills tumble ironorsteel ballswith the ore. Theballsare initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed toball mills(dry basis) is typically 75 vol.-% ore and 25% steel. Theball millis operated in closed circuit with a particle-size measurement device and size-control cyclones.

ball mill vs conical ball mill
