Fine grinding device for high-purity fused quartz powder and grinding method thereof

Abstract

According to the fine grinding device for the high-purity fused quartz powder and the grinding method of the fine grinding device, a deep neural network model based on deep learning is used for encoding a monitoring video in the grinding process and a sound effect generated in the grinding process; fusing the feature representations of the two features in the high-dimensional feature space based on the scale migration certainty to obtain a classification feature matrix containing the real-time change feature of the granularity of the to-be-ground object and the change feature of the grinding sound effect; and a classification result of whether the grinding rotating speed of the grinding machine at the current time point needs to be increased or decreased is obtained through the classifier, so that the modulated grinding rotating speed can adapt to the optimal grinding speed requirement of the object to be ground at the current time point, and the grinding efficiency is improved.

Description

technical field [0001] The present application relates to the field of intelligent equipment, and more particularly, to a fine grinding device for high-purity fused silica powder and a grinding method thereof. Background technique [0002] Quartz powder, also known as silicon powder, is a hard, wear-resistant and chemically stable silicate mineral. Because of its high whiteness, no impurities and low iron content, it has a wide range of applications. Fused silica powder is a kind of quartz powder product. In the production process of fused silica powder, the grinding of its raw materials is very important. The existing ball mills mainly rely on the grinding of raw materials, which need to go through pre-grinding, primary screening, primary grinding, re-screening, and re-grinding several times at different speeds. Only grinding and repeated screening can obtain quartz powder with a certain precision, and the production efficiency is low. [0003] Therefore, a grinding devic...
