How to Make the Cold Work of Medium-speed Coal Pulverizer in Winter

The temperature will usually affect the performance of the medium-speed coal mills. The winter season is approaching this year, and the temperature will be lower and lower. How can the mining industry protect the medium-speed coal mills from cold?


The crushing equipment such as medium-speed pulverizers, medium-speed cone mills and counter-attack medium-speed pulverizers will not only reduce the service life of the crushing equipment if the temperature is relatively low, but also make the medium speed The water or oil in the coal mill freezes. Therefore, it is necessary to perform a thorough inspection and maintenance of the medium speed coal mill before entering the winter. Maintenance of medium-speed coal mills in winter needs to start from the following aspects:

First, the speed of coal mill cleaning

Regular cleaning of the components such as the chassis and working devices of the medium speed coal mill can effectively remove the dirt on the surface of the medium speed coal mill. At the same time, during the cleaning process, it can also find whether the various parts are worn out for further maintenance. Lay the foundation. When cleaning, it should be noted that it is forbidden to use high-pressure and high-temperature water guns to clean electrical parts and other parts to avoid damage.

Second, the selection and replacement of oil

1, the choice of fuel oil

Under low temperature environment, diesel oil is easily waxed, the viscosity is increased, the fluidity becomes worse, resulting in incomplete combustion and reducing the power of the diesel engine. In order to reduce the fuel consumption of diesel fuel, it is necessary to use diesel fuel with a lower freezing point. Moreover, it is necessary to clean the fuel system, thoroughly clean the filter screen, and check the condition of the oil pump to eliminate hidden dangers.

2. Replacement of diesel engine oil

Diesel engines should use low-temperature oils with relatively low viscosity. The use of high-performance engine oil not only makes it difficult to oxidize the engine oil at high temperatures, but also avoids deposits on diesel engine components, which in turn extends the life of the engine.

3, replacement of lubricants and grease

When winter comes, it is best to replace gear oil in the transmission and differential with gear oil that can be used in winter.

Third, the maintenance of parts and components

1. In the maintenance of the diesel engine cooling system, it is necessary to check the working status of the thermostat. Once it is found that there is siltation in the tank, it must be removed immediately.

2. Check whether the battery's motor wiring is normal. In winter, it is necessary to charge the battery frequently and maintain the preheating device.

3. The maintenance of the brake system needs to check whether the brake fluid is sufficient, whether the oil-water separator and the anti-fouling switch are normal. For the phenomenon that the brake is weak and the deviation is not normal, it must be adjusted in time.

Experts remind users that in the cold winter, we must take reasonable measures to protect your medium-speed coal mill.
