The high and lowpressure zones, which are created within the oil on each side of the area of minimum film thickness, can cause oil cavitation in these bearings. Cavitation is a result of expansion of dissolved air or a vapor (water or fuel) in the lowpressure zone of the bearing. The resulting bubble implodes, causing damage, as it passes ...

Jun 27, 2002 · Lowpressure and hightemperature conditions in the grinding mill were found to greatly improve the efficiency of the size reduction of graphite. Natural flaky graphite of −100 mesh was ground into submicron sizes and more than 90% of the product were able to be reduced below 1μm without disrupting their crystallinity in a short period of time.

Oil Storage. In largescale mills the purified and dried oil is transferred to a tank for storage prior to dispatch from the mill. Since the rate of oxidation of the oil increases with the temperature of storage the oil is normally maintained around 50°C, using hot water or lowpressure steamheating coils, to prevent solidifiion and fractionation.
