Energy Consumption in Mining Comminution - ScienceDirect
2016年1月1日 Whereas crushing is usually a dry process, grinding is usually performed wet to provide a slurry (liquid) feed to the chemical concentration process [15]. With rock reduced to a manageable size by crushing, grinding mills then reduce the rock even more to a particle size that makes chemical processing viable.
