The lining can be said to be a core component of a energy-saving ball mill. It protects the inner cylinders of the equipment in the production process, because the inner cylinders are subject to various impacts in long-term operation and will inevitably be damaged. Therefore, choosing a good lining is an important prerequisite for extending equipment life. In addition, during normal production, we should regularly check and maintain equipment to ensure that the equipment is working well and creates greater value for the company.
The polishing fineness of energy-saving ball mills is directly affected by the size of the discharge port rinsing water and the supply of ore supply. The energy saving ball mill increases, the grinding concentration is thinner, the grinding fineness is thick. In contrast, the water supply ball mill is reduced, the grinding concentration is large, and the grinding is thinner.
The flushing water at the discharge port of the energy-saving ball mill is large, and the overflow is thin, and the fineness of the overflow is thin. In contrast, the flushing water at the discharge port of the energy-saving ball mill is small, the overflow has become thick, and the fineness of the overflow has become thick. In production, when other conditions remain unchanged, in order to improve the fineness of the polishing, the water supply of the energy-saving ball mill can be reduced, and the flushing water of the energy-saving ball mill is increased. At the same time, these two conditions are adjusted to ensure as many as possible. Reduce fluctuations in ore blades due to adjustment of polishing fineness, thereby reducing flotation fluctuations.
In the process of use, we often find that the temperature of the energy-saving ball mill and the motor bearing increases to the above specified. Don't worry about this problem. First try to test whether the bearing is part or completely overheat, then check the energy-saving ball mill from the following aspects.
Check the lubrication point of each part of the energy-saving ball mill, whether the lubricant brand used is consistent with the manufacturer's manual. Check if the lubricating oil and oil fat of the energy-saving ball mill are deteriorated. Check if the lubrication line of the horizontal energy-saving ball mill is blocked, or the lubricating oil does not directly enter the lubrication point, and the amount of oil can cause heat.
The oil-saving ball mill has excessive or too small in the rolling bearing of the ball mill. Excessive causes the rolling element to stir the fat, and heat will not be easily distributed. If there is too little lubrication, enough oil should be added according to the regulations, generally should be 1/3 to 1/2 of the bearing gap.
The side gap of the ball bushing of the energy-saving ball mill is too small, the gap between the bushing and the shaft is too large, and the contact point is too much, and a uniform oil film cannot be formed on the bushing. The sealing device at both ends of the grinding body is too tight, or the ferrite of the sealing body directly contacts the grinding shaft. The above problem should be processed according to the cause. Only the side gap of the bearing bushing is too small or the bottom contact angle is too large, and the cylinder must be used with a hydraulic jack, and then the bearing bushing is pulled out from the side of the shaft and scraped off.
