Red Star explains how to control the temperature of the ball mill lubricant during the beneficiation process

The ball mill is an indispensable grinding device in the beneficiation production line. During the operation, its components gradually increase with the operating temperature of the equipment. In this case, the Red Star machine usually recommends that you use the lubricant properly to ensure good lubrication of the spindle. However, some customers report that the temperature of the lubricating oil is high during the operation of the equipment. How to control the temperature of the lubricating oil of the ball mill?

Generally, the power of a large ball mill is generally about 5000-6000 kW, so the heat of the ball mill is very large. Such a large motor power will definitely cause a large power loss, and when the oil temperature is too high, the viscosity of the lubricating oil is too small. It will accelerate the aging of the medium, so that the oil film between the hollow shaft and the bearing bush will become thinner. In severe cases, the phenomenon of "burning tile" will occur; when the temperature is too low, the viscosity of the lubricating oil will be too large, which will increase the flow resistance of the pipeline, which is not conducive to the medium. The elimination of air bubbles will also make it difficult for the oil pump to suck oil and the system to return oil, so the oil temperature must be strictly controlled.

Friends in the mining industry know that the oil temperature control of the lubrication system of the ball mill is very important in the beneficiation production line. How to control the oil temperature and temperature?

First, an oil cooler is provided in the lubrication system of the ball mill to cool down. For the cooler, the flow rate is selected to be high, so that the resistance is large and the heat exchange efficiency is correspondingly increased.

The second is to increase the volume of the fuel tank when the ball mill is designed. When the volume of the fuel tank is increased, the temperature of the lubricating oil is lowered, and the structure of the fuel tank can be optimized to allow the lubricating oil to be sufficiently dissipated in the fuel tank.

If the ball mill has been designed, it is very wasteful to control the temperature of the lubricating oil. It is very wasteful to design the oil tank. At this time, we can consider the choice of lubricating oil. We can choose synthetic oil with high viscosity index and low evaporation loss. The temperature is lowered.

In short, the oil temperature control of the ball mill lubricant is very important. If the oil temperature is not well controlled, it may have serious consequences. The Red Star machine reminds everyone to pay attention to the oil temperature control of the ball mill lubricant!
