At present, most small ball mills appear in market are equipped with medium diameter roller bearing. These kind bearing bases mostly adopt dry oil lubrication. But in recent years, because the operator and oilman cannot observe the oil level and complement oil in a timely manner, resulting in lubricating greases in bearings mounted in the box cannot be clearly reflected and leads a shortage of oil. This will not only cause a shortened service life of bearings, but also can cause damage to bearing. It will bring bearing manufacturers a lot of inconvenience and economic loss. In order to solve this problem, Hongxing Mining machinery has recently developed thin oil rolling bearings lubrication. This new form of hollow shaft with rolling bearing installation method is a progress and improvement on the basis of the original installation method. This new thin oil lubrication bearing seat is essential to ensure good lubrication of the bearing.

The lower part of such bearing base consists of two oil rooms and a circulating water room. In each lubricating oil room, the oil height can reach in the position of inner diameter of the bearing, the floor plane can reach the oil room floor. One-third volume of rolling bearing is immersed in thin lubricating oil room, which ensures good lubrication of rolling bearings. There is circulating cooling water between the two oil rooms, and cooling water will cool bearings to a proper temperature. So, it is able to guarantee bearing lubrication requirements, and does not need to use such complex peripheral facilities as extra lubrication station, neither install temperature control device, this system itself can achieve safe operation.

Attention given to bearing buyers that when you are reforming small ball mill main shaft into rolling bearings, you had better adopt boss method to install ball mill hollow shaft, rolling bearing and thin oil lubrication bearing base. It is a must to ensure ball mill good running condition in the long run.

Ore dressing ball milling equipment plays a decisive role in rapid development of city and high way, high rail construction. Therefore, we must pay more attention to ball mill quality. Besides, nowadays we are calling for low carbon high efficiency all over the world, so the daily equipment efficiency should also be counted into consideration. After bought high efficiency quality equipment, what things left are equipment maintenance and repair. And the maintenance is not just related to human labor force, but a technology project. The training and cultivation to maintenance and repair workers is a safety guard to ball mill reliable operation.
