Vertical grinding mill loading pressure control system and method and storage medium

Abstract

The invention provides a vertical grinding mill loading pressure control system and method and a storage medium. The system involves a vertical grinding mill hydraulic station, a treatment device, a vertical vibration sensor arranged on a base of a speed reducer of a grinding main machine of the vertical grinding mill, a weighing device arranged at a material returning position of the vertical grinding mill and a mutual inductor arranged at the output end of a frequency converter of the vertical grinding mill, wherein the vertical vibration sensor is used for obtaining the vibration value of the grinding mill from the base of the speed reducer of the grinding main machine of the vertical grinding mill. According to the system, the adjustment steps of a mill system for an action of a grinding roller and loading can be greatly reduced, and the manual intervention is not needed in the whole process; materials can be automatically adjusted according to current judgment data so that the grinding efficiency of the mill can automatically tends to be stable; and for unexpected conditions such as material accumulation in the mill caused by the change of the granularity of raw materials and the problem of a mill conveying system, corresponding measures can be automatically taken for automatic adjustment, so that human resources invested due to instability of the mill are greatly reduced.

Description

technical field [0001] The present invention mainly relates to the technical field of pulverizer control, in particular to a loading pressure control system, method and storage medium of a vertical pulverizer. Background technique [0002] The grinding method of the vertical mill is to control the grinding roller to be loaded on the material through the hydraulic station, and the grinding host rotates to drive the grinding disc to rotate the material, so that the materials can rub against each other to achieve the purpose of grinding. The current control method is: [0003] 1. When the material is fed until the grinding disc is full, there is material overflow at the material return port; [0004] 2. Manually control the loading of grinding rollers, and manually adjust the loading pressure; [0005] 3. If the mill vibrates, lift the roll manually and load it again after a while; [0006] 4. If the mill is stable after loading, observe and adjust the loading pressure until...

AI Technical Summary

Problems solved by technology

[0009] It can be seen that the manual intervention process from the beginning of loading and grinding to the stage of stable output of finished products by the mill is relatively complicated, and requires a high level of operator. If the raw material is unstable, the grinding condition of the mill will decrease, resulting in a decrease in the output of finished products; Intervention until the mill is stable The operator must always concentrate on adjusting the parameters, which is not conducive to the simplification of operation control
