Embodiment Construction

[0072] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0073] In order to make it easier for those skilled in the art to understand the technical solutions provided by the embodiments of the present disclosure, the following explanations are given first.

[0074] Usually, the inner wall of the cylinder used for mixing materials and grinding balls is provided with a liner. When the mill rotates, the grinding medium is attached to the liner and rotates with the cylinder under the action of centrifugal force and friction force. When it reaches a certain height After that, it is thrown down by its own gravity.

[0075] In the actual application process, as the mill speed increases from low to high, the motion state ...

Abstract

The invention provides a mill work state adjusting method and device. The method comprises the steps of collecting sound signals of work of a mill, and extracting impact data frames of a grinding medium impact lining plate from the sound signals; according to the impact data frames, positioning the impact position of the grinding medium impact lining plate; according to the impact position, determining the toe position of the mill; judging whether the impact frequency when the impact position is located above the toe conforms to the preset frequency or not, if not, adjusting the work state of the mill; according to the scheme, in-time adjusting the work state of the mill can be achieved, the lining plate above the toe is directly impacted by the grinding medium as little as possible, the mill can be kept in the optimal work state to the greatest extent, and the whole work efficiency of the mill is improved.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a method and device for adjusting the working state of a mill. Background technique [0002] The mill is the key equipment for crushing and grinding after the material is crushed. It is an extremely important high-fine grinding equipment in industrial production and is widely used in metallurgy, mining, building materials and chemical industries. Generally, a mill may include a horizontally arranged cylinder, an inlet, an outlet, and the like. The crushed material enters the cylinder through the feeding port, and mixes with the grinding balls and water in the cylinder. When the cylinder rotates around the horizontal axis at a certain speed, the grinding medium (including the grinding ball and the material) is crushed under the influence of centrifugal force and friction. Under the action, after being brought to a certain height, it is thrown down by its own gravity. ...
