Problems solved by technology

[0010] Through the published technical solutions for the research on the energy consumption factors of ball mills, we can understand that the existing technical solutions in the industry have done research and analysis on the processing process of ball mills at different levels based on different starting points, but the conclusions obtained are obviously lack of unity. argument
Especially in the process of ball mill processing, which factors affect the energy consumption of the ball mill, and how much each factor contributes to the energy consumption of the ball mill, which is a common concern, has not been effectively answered.

Abstract

The invention discloses a ball-grinding-mill particle track analysis and energy consumption modeling method based on a DEM. The two technical schemes of theoretical modeling and DEM simulation are combined, on the basis of adopting some existing technical schemes, influences of changes in multiple factors such as the ball-grinding-mill rotating speed, the particle size, the ball-grinding-mill inner diameter and the particle filling rate on the energy consumption of a ball grinding mill are compared and analyzed, the technical results of the ball grinding mill for the potential influence factors are finally obtained, and the specific degrees of the influences of the potential energy consumption influence factors on the energy consumption of the ball grinding machine are given; on the basis, the technical scheme for optimizing the energy efficiency of the ball grinding mill is provided. By means of the ball-grinding-mill particle track analysis and energy consumption modeling method, the factors influencing the energy consumption of the ball grinding mill in the machining process of the ball grinding mill and the degrees of the influences of the factors on the energy consumption of the ball grinding mill can be effectively analyzed and obtained, and the ball-grinding-mill particle track analysis and energy consumption modeling method is of remarkable significance in solving the industrial problems and promoting the industrial technical advancing.

Description

Technical field [0001] The invention relates to the technical field of energy consumption analysis of a ball mill, and more specifically, to a DEM-based method for ball mill particle trajectory analysis and energy consumption modeling. Background technique [0002] Ball milling is an important process in the architectural ceramics industry. On the one hand, the quality of the powder particles produced by ball milling will directly affect the subsequent pressing and sintering links, and ultimately affect the product quality; on the other hand, in the high-energy-consuming building ceramics manufacturing industry, the ball milling process It accounts for 1 / 3 of the total energy consumption. Therefore, exploring the factors that affect ball milling quality and energy consumption and optimizing various parameters in the ball milling process are of great significance for improving production quality and energy efficiency. [0003] The research methods of ball mills are mainly divided i...
