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

The invention provides a loading pressure control system, method and storage medium of a vertical pulverizer, including a vertical pulverizer hydraulic station, a processing device, and a vertical vibration sensor arranged on the base of the vertical pulverizer grinding host reducer 1. The weighing equipment arranged at the return material of the vertical mill and the transformer arranged at the output end of the frequency converter of the vertical mill; The vibration value of the mill is obtained in the seat. The invention can greatly reduce the adjustment steps of the mill system for the action and loading of the grinding rollers, without manual intervention in the whole process, can automatically adapt to the material for the current judgment data, and automatically stabilize the grinding efficiency of the mill. Sudden accidents such as material accumulation in the mill caused by system problems can also automatically take corresponding measures to automatically adjust, greatly reducing the human resources invested due to the instability of the mill.
Description
Technical field [0001] The present invention relates mainly to the field of mill control technology, specifically to a vertical mill loading pressure control system, method and storage medium. Background [0002] The vertical mill grinding method is to control the grinding roller loaded onto 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. Feed to the full material of the grinding disc, and there is material overflow at the return port; [0004] 2. Manually control the loading roller and manually adjust the loading pressure; [0005] 3. If the mill vibrates, manually lift the roller and load it again after a moment; [0006] 4. If the mill is stable after loading, observe and adjust the loading pressure to the grinding host current stability (rated value) and there is no return o...
