Description

Technical Field

[0001] The utility model belongs to the technical field of comprehensive utilization of red mud, in particular to a ball mill journal lubrication mechanism. Background Art

[0002] Red mud is an industrial solid waste discharged when the aluminum industry extracts alumina. Because it contains a large amount of iron oxide and looks similar to red soil, it is called red mud. As China is a major alumina producer, with the increasing amount of red mud stockpiles and the increasingly serious pollution to the environment, it is imperative to maximize the resource utilization of red mud.

[0003] Red mud is generally processed by dry and wet methods. In the dry process, the red mud is generally filtered, mixed, roasted, and then ground and magnetically separated to remove high-grade iron. The grinding stage is generally carried out using a ball mill.

[0004] The working principle of the ball mill is realized through a horizontally placed rotating cylinder. Grinding bodies such as steel balls and steel forgings are installed inside the cylinder. These grinding bodies rotate with the cylinder under the action of centrifugal force and friction, and fall freely under the action of gravity, impacting and grinding the materials. During the rotation of the mill, the grinding bodies will also slide and roll to further grind the materials.

[0005] The journal of the ball mill not only bears the role of bearing rotation and guiding, but also serves as the feeding function of the ball mill. The existing ball mill journal and the support seat are lubricated with lubricating oil, and oil seals are set at both ends to block and achieve the effect of dust prevention. However, after running for a long time, oil sludge is inevitable. If it is not cleaned for a long time, it will cause strain and cause the machine to vibrate and make abnormal noises. Therefore, it is necessary to improve the existing journal. Utility Model Content

Combined with the lubrication of lubricating oil, the friction between the bearing 5 and the ball mill shaft neck 3 is further reduced, and the bearing 5 can be replaced, which is more convenient. The four thrust plates 7 form two rings, and the thrust plate slots 6 can prevent the bearing 5 from moving, thereby improving the stability of use. Finally, the lubricating oil after lubrication is drawn into the oil storage chamber 1011 through the oil return hole 1012 by gravity and is used reciprocatingly.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
