Abstract

The invention relates to a ball mill impact detection device, an impact detection and a ball mill speed regulating method, and relates to the ball mill detection device and the technical field. It is characterized in that: the lower part of the ball mill cover (2) is provided with a protective head (3) that can be plugged into the opening of the ball mill (1), and the ball mill cover (2) and the protective head (3) are coaxially provided with a through hole that penetrates up and down, and the through hole Install the detection rod (4) inside the bottom end of the ball mill (1) through the lower hollow screw (5), and the upper end of the lower hollow screw (5) is connected to the ball mill cover (2) through the upper hollow screw (12), and the detection rod (4) ) The electromagnetic induction device is installed on the top, and the spring (6) is installed in the space between the electromagnetic induction device and the ball mill cover (2); the impact force detection method of the ball mill impact force detection device obtains the data relationship curve through the simulation experiment, and detects the ball mill. The impact force on the inner wall is large, which provides data support for adjusting the speed of the ball mill, and ensures the grinding efficiency and service life of the balls in the ball mill.

Description

technical field [0001] The invention relates to a ball mill impact detection device, an impact detection and a ball mill speed regulating method, and relates to the ball mill detection device and the technical field. Background technique [0002] The ball mill is the key equipment for crushing and grinding after the ground material is crushed. It is the most important high-fine grinding production equipment in industrial production enterprises. During the working process of the ball mill, the main working medium inside the ball mill is the ball stone, and the materials in the ball mill are ground by the impact force of the ball stone. However, the ball stone is also impacting the inner wall of the ball mill while grinding the material. When the ball mill is designed and manufactured, the value of the internal impact force is clearly stipulated. If the ball mill is working, the internal ball stone impact force is higher than this value. It will affect the grinding particle s...
