For example, in hot weather, the ultra-fine grinding mill itself will generate a certain temperature when it is produced, and the outside temperature is also very high, which will prevent the temperature of the equipment itself from dissipating. Intensified molecular movement of internal parts, resulting in deformation of parts, etc. To solve this problem, we need to start with the following aspects: Tn a hot environment, pay more attention to the daily maintenance and inspection of the equipment. The selected lubricating oil must have a high ignition point to prevent the occurrence of flammable conditions. The above introduces the working conditions of ultrafine vertical mill in hot weather from three aspects. It is to pay attention to cleaning work, heat dissipation work and the choice of lubricating oil. These three aspects can effectively ensure the normal operation of the equipment and avoid the reduction of production efficiency. The situation happened.
