The CPS energy of the inlet trunnion vibration is more sensitive to the variation in coal feeding rate than that of mill noise. The CPS energy of inlet trunnion vibration can therefore represent the mill load of the inlet side well, while the CPS energy of mill noise primarily represents the mill load of the whole mill. (3)
What weight of oil is the Mill Manufacture recommending?( this 460 oil seems very heavy to me.) I know Gibraltar had lube pumps and (I call them) dip cups, which were cups attached to the trunnion that would turn with the mill filling with oil pouring over the trunnion as the mill was turning. this is old school. How old are these mills?
