In contrast to the two energy-saving ball mill bearings, we can first distinguish the structural features. The rolling bearing is supported by the rotation of the rolling elements to support the rotating shaft, so the contact point is a point. The more the rolling elements, the more the contact points. The sliding bearing is supported by a smooth surface to support the rotating shaft, so the contact area is a surface. . Sliding bearings are also bearings that work under sliding friction. The part where the shaft is supported by the bearing is called a journal, and the part that matches the journal is called a bearing. The friction-reducing material layer cast on its inner surface to improve the frictional properties of the pad surface is called a bearing lining.

In addition, the application of energy-saving ball mill sliding bearings is generally under low-speed heavy-duty operating conditions, or is difficult to maintain and refill lubrication operating parts. The roller bearing energy-saving ball mill is replaced by a rolling bearing bearing structure and a positioning anchor to prevent axial displacement, which increases the service life and saves oil, water and electricity consumption. In general, the energy-saving ball mill rolling bearings are easy to use and maintain, work reliably, and have good starting performance and high bearing capacity at moderate speeds. Compared with the plain bearing, the radial dimension of the rolling bearing is larger, the vibration-reducing ability is lower, and the life at high speed is low and the sound is louder. The series of compound fertilizer production lines produced by Henan Pipao, jaw crushers and other crushing equipment have played a decisive role in the development of the mine crusher industry in China!

Different from the exercise mode, the energy-saving ball mill roller bearings and sliding bearings are distinguished, in which the rolling bearing movement mode is rolling and the sliding bearing movement mode is sliding, so the friction situation is completely different. Sliding bearings work smoothly, reliably, and without noise. Under the conditions of liquid lubrication, the sliding surfaces are separated by lubricating oil without direct contact, and friction loss and surface wear can be greatly reduced. The oil film also has a certain ability to absorb vibration, but the starting friction Greater resistance. The rolling bearing rolling body distributes the rolling elements uniformly between the inner ring and the outer ring by means of the cage. The shape and quantity of the rolling bearing directly affect the performance and life of the rolling bearing. The cage can evenly distribute the rolling elements and prevent the rolling elements from rolling. Fall off, guide the rolling element to rotate and start the lubrication of the energy-saving ball mill.
