Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a roller gap adjusting device for roller presses. Background Art

[0002] The roller gap adjustment device of the roller press is a device used to adjust the gap between the rollers of the roller press. The roller press is a kind of crushing equipment in the cement production process. It relies on the mutual squeezing of two rollers to crush the materials to meet the needs of cement production. The roller gap adjustment device of the roller press is very important for the working effect and product quality of the roller press. If the roller gap is too large, the rollers will not be able to effectively press the materials, and the working effect will be poor; if the roller gap is too small, the rollers will not be able to rotate normally, and may even damage the rollers. Therefore, the adjustment of the roller gap needs to be reasonably adjusted according to the specific process requirements and product characteristics.

[0003] However, when using some existing roller gap adjustment devices for roller presses, most of them require the roller press to be stopped first, and then the gap between the two rollers is adjusted. Because of the need to stop the machine for adjustment, the overall working efficiency of the roller press is low. Therefore, this problem needs to be solved. Utility Model Content
