Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] In the mineral crushing process, various types of mills are mainly used for fine particle crushing operations. With the increase of mineral processing capacity in mines, the application of large grinding equipment such as semi-autogenous mills is becoming more and more extensive. This type of grinding equipment usually has a large geometric size and strong mineral processing ...

Abstract

The invention provides a method and a device for measuring an ore grinding state of a mill, and electronic equipment. The method comprises the steps of: acquiring state parameters of the target mill on a current workday; determining coordinates and an impact angle of a throwing motion impact point of the outermost ore grinding medium in the target mill according to the state parameters; determining a mineral distribution ore toe angle in the target mill according to a preset estimated value of an internal mixed filling rate of the target mill and a ratio of an actual mill rotating speed to a critical mill rotating speed; and determining the ore grinding state of the target mill in the current workday according to an impact angle, the mineral distribution ore toe angle and a pre-establishedjudgment model. According to the method and the device, an existing online measurement method for the ore grinding state of the mill can be effectively improved, and the ore grinding state of the mill is visually displayed.

Description

technical field [0001] The invention relates to the technical field of on-line detection of mineral processing, in particular to a method, device and electronic equipment for measuring the grinding state of a mill. Background technique [0002] As one of the core processes of the mineral processing process, the mineral crushing process mainly uses various types of mills for fine particle crushing operations. With the increase of mine mineral processing capacity, the application of large grinding equipment such as semi-autogenous mills is also more extensive. At present, the online analysis of the grinding state of semi-autogenous mills usually relies on experienced operating experts to make comprehensive judgments through motor current, shaft pressure, electric ear signals, vibration signals, etc. However, these signal values ​​are not strongly related to the grinding state in appearance, and cannot intuitively show the current working state of mineral distribution and crus...
