Description

Technical Field

[0001] The invention relates to the technical field of visual detection, and in particular to a roller surface monitoring device for a high-pressure roller mill. Background Art

[0002] High-pressure roller mill is mainly used for fine grinding of ore. The ore is squeezed by two rollers to obtain fine-particle fine grinding products. The two rollers are covered with roller nails, which bear the squeeze of the ore and are under great force. After a period of use, the roller nails will break or fall off. At this time, it is necessary to stop the machine for inspection and replace the roller nails. If the roller nails cannot be replaced in time, the ore will damage the roller body, causing economic losses to the company and affecting the product particle size of the ore. However, due to the large amount of dust inside the high-pressure roller mill and the harsh environment, how to effectively monitor the roller surface in real time is a problem that many mining companies need to solve.
