Description

Technical Field

[0001] The utility model relates to the technical field of comprehensive iron removal before slag grinding, in particular to a slag grinding. Background Art

[0002] With the continuous development of cement technology, the grinding system is also undergoing a series of important changes. One of the widely popular concepts is "more crushing and less grinding", that is, increasing the crushing input, reducing the particle size of the raw materials entering the mill, and reducing the load of the grinding system, so as to reduce power consumption and save costs. However, once the materials are mixed with iron slag or iron components during the production process, it will cause damage to the grinding equipment. At the least, it will cause increased wear of equipment components such as rollers and reduce the life of the equipment. In severe cases, it will increase the power consumption of the equipment, reduce the output of the mill, and even cause the vibration of the mill, causing equipment damage. As the particle size of the materials entering the mill gradually becomes finer, the impact of this iron debris is also gradually increasing, so effective iron removal is an important step that cannot be ignored to ensure the normal operation of various grinding equipment.

[0003] When slag is ground, the slag material falls to the middle of the grinding disc through the feeding device. As the grinding disc rotates, it gradually spreads to the edge of the grinding disc under the action of centrifugal force and enters the grinding area of ​​the grinding disc and the grinding roller. The ground material continues to move to the edge of the grinding disc and gradually accumulates at the retaining ring. When the slag material contains iron slag, since the specific gravity of the iron slag is greater than that of the slag, the iron slag will be deposited at the bottom of the material layer in the form of small spherical particles. At the angle formed by the retaining ring and the grinding disc liner, it is not easy to be thrown out of the edge of the grinding disc. Therefore, a slag mill is designed to remove iron chips from the slag in view of the high specific gravity and magnetic properties of iron slag. Utility Model Content
