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 ball mills, and more specifically, to a DEM-based particle trajectory analysis and energy consumption modeling method of ball mills. Background technique [0002] Ball milling is an important process in the building 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 product quality; on the other hand, in the high-energy Accounted for 1 / 3 of the total energy consumption. Therefore, it is of great significance to explore the factors that affect the quality and energy consumption of ball milling and to optimize various parameters in the ball milling process for improving production quality and energy efficiency. [0003] Research methods for ball mills are mainly divided into two categories. The first type is to use the basic physical and chemi...

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.
