The production process of the ball mill is continuous, and the material in the roller is, directly affects the production capacity and product quality of the mill. Detect control of the ball mill is an important parameter that guarantees the normal operation of the grinder. However, since the material is operational as the roller is not stopped, this is difficult to test. A plant introduces a ball mill for anode carbon production, setting two types of differential pressure and sound types.
The former is the contact measuring device, which is simple to process the material discharge detection of the powdered material re-ball mill without viscous, non-corrosive and complementing. The latter is a non-contact measuring device with reliable use. , No mechanical damage, unconfilled material, and can be maintained offline maintenance. Differential pressure and audio level measurement devices have advantages. When the material surface is lower, in order to measure the differential pressure, the extracting tube must be inserted into the depth. At this time, the pressure pipe is constantly hit by the steel ball, it is easy to damage, so the low level, differential pressure The method is constrained. In addition, its control zoning is also limited by the height difference of the two conductors, which is related to the bulging capacity of the ball mill. When the sound type method is low in the material surface, the sound intensity is large, the material surface is slightly changed, and the change in sound intensity is also large.
Therefore, the sound type detection is better when the material surface is low. However, when the surface of the material is high, the change in the sound intensity of the material dispersion is not significant, and the detection effect is not satisfactory. Two level detection control methods are installed on the ball mill, according to the results of operation, select one of the common mode, the other as a standby. According to our debugging situation, within the normal level range, the sound type detection control is better, so the differential pressure is used as a standby. After more than ten years of actual operation, the audio level detection control system is basically normal, the maintenance amount is small, the failure rate is low, and the effect is good.
