Description

Technical Field

[0001] The utility model relates to the technical field of metal parts surface surfacing modification equipment, in particular to a grinding roller surfacing device used for blast furnace slag grinding. Background Art

[0002] For a long time, blast furnace slag has been mainly used by cement manufacturers, especially vertical kiln cement manufacturers, as a mixed material to accelerate the dissolution of free calcium in cement clinker, reduce cement costs, increase cement production, etc. Experiments have shown that the activity can only be stimulated when the slag is ground to a specific surface area of ​​more than 350㎡ / kg, and the higher the specific surface area, the better the activity, which can even exceed the activity of cement. Manufacturers usually need to grind blast furnace slag separately first. In the prior art, one of the important components of blast furnace slag grinding equipment: the grinding roller, will produce severe wear after long-term use. Wear will cause the efficiency of the vertical mill to decrease. During regular maintenance, the grinding roller must be repaired. The repair of the grinding roller often uses surfacing technology to repair the worn parts of the grinding roller fan surface.

[0003] In the prior art, the surfacing device for grinding roller repair often adopts a fixed support drive table as the support structure of the grinding roller to meet the support requirements for the grinding roller in the surfacing stage. In actual use, due to slight differences in the distribution positions of the wear areas of the grinding roller, the wear positions of the grinding roller are on the fan-shaped part of the outer surface and the top circular ring part. When the wear is serious, in addition to the fan-shaped surface, the intersection of the circular ring surface at the top and the fan surface will also be worn, resulting in sloped wear surfaces with different angles, resulting in the above-mentioned fixed support drive table being difficult to meet the current repair needs of the grinding roller.

[0004] To this end, a grinding roller surfacing device for blast furnace slag grinding is proposed, which has the advantage of convenient and flexible adjustment of the grinding roller repair position, thereby solving the problems in the above-mentioned background technology. Utility Model Content
