So the measurement of ball mill load has a important significance of production at the aspect of ensuring safety, improve efficiency and reducing energy consumption. because the ball mill load was influenced by many factors with complex relationships, the detection became difficult which is still a technological difficulties for a long.
The control philosophy controlled to a mill load set-point by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. this is all a commissioning exercise and one of the things we wanted to do was - incorporate an additional loop whereby mill speed is automatically adjusted to control mill.
The real-time working conditions of the ball mill in the grinding process are complicated, which makes it difficult to accurately obtain the internal load status of the ball mill. in this paper, the energy difference between the original cylinder vibration signal and the intrinsic mode function is proposed as the evaluation parameter of the adaptive variational mode decomposition (vmd) layer.
This paper presents a solution for the detection and control of coal loads that is more accurate and convenient than those currently used. to date, no research has addressed the use of a grinding medium as the controlled parameter. to improve the accuracy of the coal load detection based on the kinetic energy of balls in a tubular ball mill, a discrete element method (dem) model for ball.
To improve the accuracy of the coal load detection based on the kinetic energy of balls in a tubular ball mill, a discrete element method (dem) model for ball kinematics based on coal loads is proposed. the operating process for a ball mill and the ball motion, as influenced by the coal quality and the coal load, was analyzed.
