In recent years, the production of ball mill tends to be large-scale, specialization, the traditional edge drive ball mill mechanical loss is serious, it has been difficult to meet the production demand, red star machine after experimental research, found that the main bearing of the ball mill to improve, can significantly improve the production efficiency of the ball mill, but also to achieve the effect of saving electricity, water and oil.
The mechanical loss of traditional edge-driven ball mill is 10%~14%, and the sliding bearing system which carries the main load of the mill is the main part of energy loss. In the past, due to the limitations of material properties, processing and manufacturing technology, the main bearings of ball mills all use sliding bearing system. Sliding bearing friction coefficient is about 0.04, while the friction coefficient of energy-saving mill rolling bearing is 0.0025, which is only 1/16 of the friction coefficient of sliding bearing, that is to say, the starting torque of the main bearing of the sliding friction mill, the running resistance and customer service mechanical friction resistance of the power required for the use of rolling friction mills are 16 times.
Changing the ball mill bearing system from traditional sliding bearings to rolling bearings, with less modification, short transformation time and less investment, without changing the installation dimensions and process parameters of the original machine, in the process of using, the rolling bearings are easy to maintain, work reliably, have good aerodynamic performance, and have high load carrying capacity at medium speed.
Rolling bearings are one of the widely used components in modern machines, relying on the rolling contact between the main elements to support the rotating parts. Compared with sliding bearings, rolling bearings have the characteristics of easy maintenance, small friction coefficient, low manufacturing cost, reliable work, good start-up new energy, and high bearing capacity at medium speed. Moreover, rolling bearings do not need hydraulic station, which can really realize oil saving, water saving and power saving, improve the equipment operation rate 10%~15%, and increase the economic benefit of the enterprise.
Red Star Machine found that the use of rolling bearings, ball mill running resistance is small, smooth operation, low failure rate, completely eliminate the hidden danger of burning tile, but also improve the equipment operating rate, increase the economic benefits of enterprises. And red star machine also found that after changing to rolling bearings, rolling main bearing lubrication using grease lubrication, can cancel the thin oil station; rolling bearing temperature rise is also smaller, do not need water cooling, annual cost savings of tens of thousands of dollars, but also to improve the efficiency of the equipment production, the real realization of ball mill energy saving and efficiency.
