Currently the majority of domestic manufacturers have been the first to adopt in order to save energy rolling bearings instead of spherical watts used as energy-saving ball mill bearing industry and developed a bearing standards. The main advantage of using dedicated Rolling described as follows:
1. Energy-saving
When the special ball mill using mill (rolling) bearings, the lower coefficient of friction, so start current is reduced to 40% and decreased to the normal operating current of about l0%.
2. Water-saving
Like bush mill no longer need that must be cooled with water. Using a ball mill special bearing, frictional resistance is reduced, the lower the heat generated by, the thermostat measuring under the conditions of room temperature 42 ℃ bearing temperature: Up to 30 ° C, experienced four consecutive summer, without water cooling can be used normally.
3. Fuel economy
The bearings with grease lubrication, using the top of the hole from the top of the bearing outer ring dedicated refueling, oiling (oil pump plus), this lubrication method formed in two rows of rollers in the middle of an apparent oil line: from top to under lubrication, the tramp oil from the inside out, and also play the role of self-sealing, can effectively block the invasion of outside dust. 2-3 days plus oil. The amount of grease per year only in the tens of kilograms, eliminating the need for the original lubrication oil station fuel supply can save several tons of lubricants annually. Old dirty oil while also reducing emissions.
