Description

Technical Field

[0001] The utility model belongs to the technical field of roller mill detection and relates to a high-pressure roller mill detection structure. Background Art

[0002] Roller presses are currently widely used in ultra-fine crushing applications in industries such as mining, cement, and metallurgy. They achieve increased production and efficiency by reducing grinding with more crushing. They offer advantages such as a large crushing ratio, high crushing efficiency, simple process flow, high equipment availability, and low energy consumption. The roller press control system is primarily used to ensure safe, efficient, and stable operation of the equipment.

[0003] Feedback from the operation of existing roller presses in China shows that the control system needs to be based on a large number of sensors for detection, such as detection of roller gap width, crushing pressure, roller speed, feed particle size, etc. The roller gap width refers to the distance between the movable roller and the fixed roller, and the movable roller mostly uses mechanical and hydraulic mechanisms to achieve horizontal lateral movement. It is further necessary to detect the vibration conditions of structures such as the roller shaft and coupling to support the control system data and display it on the interactive interface. At present, the data is wired in an independent manner and lacks relevance. In addition, since the vibration sensors of the roller shaft or roller sleeve are located in the high-pressure roller mill, they are in a relatively complex environment during high-speed roller pressing. The installation is prone to interference or collision with materials, which is not conducive to detection. Summary of the Invention

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] Inspection of a high-pressure grinding roller (HPGR) requires monitoring multiple locations, including roll gap width, crushing pressure, roll speed, and feed size. The roll gap width is used to adjust the distance between the moving and fixed rolls to control the size of the milled material. In actual operation, roller vibration is a key component of equipment inspection. Vibration sensors are placed at key roller locations (such as the bearing seat and roll surface) to collect vibration data. Spectrum analyzers can also be used to analyze vibration signals and identify their spectral characteristics.
