Tailings are normally not generated within this method step.Crushing could be the initial stage within the granite processing plant machineries. This is commonly a dry operation, which entails breaking down the ore by compressing it against rigid surfaces or by impacting it against hard surfaces inside a controlled motion flow. This procedure step prepares the ore for further size reduction or for feeding directly to the classification and concentration separation stages.
In grinding roller comminution the feed material is exposed to extremely high pressure for a brief time. The high pressure causes the formation of microcracks inside the feed particles and generates a substantial amount of fine material. The pressed material can be fed directly to a given size ball mill, making it possible to increase the throughput of a given size ball mill and reduce the specific power consumption of the whole mill system.
This can avoid the heating not evenly.this is the most widely used method , there is a metal mesh above 50-70mm to the bottom of the oil , the bearing would set up on the meshes , the large bearing should be lift by the hooks.
