Quartz Grinding Mill main bearing failure

                        

The high temperature of the main bearing bush of the Quartz Grinding Mill is a common phenomenon, requiring the user to cool down in time. What factors affect the temperature of the main bearing bush during the use of the Quartz Grinding Mill? There are actually many influential factors. Let us analyze them one by one.

1. The effect of friction on heat

The hollow shaft and the bearing bush rotate relative to each other, and friction generates heat. Strictly speaking, the heat generated by the oil film between the two is sheared, and the bearing temperature rises, and the value thereof is relatively small.

2. The effect of heat generated when the material is pulverized by the grinding body

When the Quartz Grinding Mill is in operation, the grinding material only accounts for a small part of the total energy consumption, and most of the energy is converted into heat energy and sound energy. For this reason, the material is getting a lot of heat, flowing through the hollow shaft or sliding When the ring is passed, the heat is transferred to the bearing bush, which will greatly increase the temperature of the main bearing, and the temperature of the bearing can reach 70~80 degrees Celsius or even higher.

3. Influenced by the type of Quartz Grinding Mill

Due to the different types of Quartz Grinding Mills, the effect on the temperature rise of the bearing bush is different. The wet raw material mill is added with slurry, the internal temperature rise of the mill is not high, the greenhouse of the main bearing of the discharge is low, the Wawen of the main bearing of the cement grinding material is high; the drying raw material Quartz Grinding Mill wind sweeps the coal Grinding while feeding, there is still hot air. If the kiln exhaust gas is used to dry the material, the inlet air temperature is 350 degrees Celsius; if the auxiliary hot air furnace is used, the temperature of the grinding gas can reach 450 degrees Celsius, so that the temperature of the main bearing is higher. The average Quartz Grinding Mill is higher.

4. Influenced by the structure of Quartz Grinding Mill

An insulation layer is provided between the inlet and outlet spiral barrels (taper sleeves) of the Quartz Grinding Mill and the hollow shaft in order to reduce the heat transferred from the material to the hollow shaft or even the bearing shell. Some Quartz Grinding Mills have a thin insulation layer, and some Quartz Grinding Mills have a thick insulation layer. For cement grinding and discharging main bearings, it is desirable to have a thicker insulation layer to prevent the transmission of heat insulation.

5. Influenced by the ambient temperature around the Quartz Grinding Mill

The ambient temperature around the Quartz Grinding Mill also affects the temperature of the bearing bush, such as the season, geographical location, and even the degree of ventilation in the workshop, which will affect the temperature of the bearing bush.

6, the main bearing cooling water temperature and the amount of cooling water

The main bearing water of the Quartz Grinding Mill includes two aspects, one is the water in the main bearing bush, and the other is the water cooler in the main bearing thin oil station. The water temperature of the cooling water has a large influence on the temperature of the tile, especially the water temperature. Because the water source is different, some plants use river water or lake water, and some use groundwater, so the temperature of the cooling water is different. The water temperature is also affected by the season.

7. Impact of peripheral thin oil stations

Quartz Grinding Mill main bearing thin oil station has two functions. One is to supply the amount of oil needed to build a dynamic oil film; the other is to take away excess heat and cool the bearing. Usually, the oil volume of the main bearing forming the dynamic pressure oil film is about 6-10 L/min; in China, 25 L/min is usually used, and some even use 45 L/min, and the amount of lubricating oil required to take away heat is included here.

By the above analysis that, factors causing the Quartz Grinding Mill main bearing bush there are many elevated temperature, to remind the user an SBM, in the device during use, should be noted that many reasonable control of the temperature of the main bearing shell.
