Abstract

The invention discloses a ball mill impact force detection device and an impact force detection and ball mill speed regulation method and relates to the technical field of ball mill detection devices. The ball mill impact force detection device is characterized in that a protective head (3) which can be stuffed into an opening of a ball mill (1) is arranged below a ball mill cover (2); an up-down through hole is coaxially formed in the ball mill cover (2) and the protective head (3); a detection rod (4), of which the bottom end is in contact with the interior of the ball mill (1), is arranged at the lower part in the through hole through a lower hollow screw rod (5); the upper end of the lower hollow screw rod (5) is connected with the ball mill cover (2) through an upper hollow screw rod (12); an electromagnetic induction device is arranged on the top of the detection rod (4); a spring (6) is arranged in a space between the electromagnetic induction device and the ball mill cover (2). According to the impact force detection method of the ball mill impact force detection device, a data relation curve is obtained through a simulation experiment, and an impact force applied to the inner wall of the ball mill is detected, so that data support is provided for adjusting the rotating speed of the ball mill, the ball stone grinding efficiency in the ball mill is guaranteed, and the service life of the ball mill is prolonged.

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...
