How to choose the right lubricant for jaw crusher

The jaw crusher is a heavy-duty equipment that operates in the open air for a long time. In order to ensure the normal operation of the jaw crusher, it needs to be well lubricated. Lubricants have many functions. Different types of lubricants have different performance characteristics. Some lubricants have better stability and oxidation resistance, while others have worse stability and oxidation resistance. Moreover, the viscosity of lubricants also varies. The difference. So, how to choose the right lubricant for jaw crusher?
 

1. Lubricant has strong stability. The size of the jaw crusher and the volume of the oil tank are small, and the amount of lubricant installed is also small. The oil temperature is high during operation, which requires the lubricant to have good thermal stability and oxidation resistance.

2. Lubricant resists corrosion and can withstand pollution. Because the jaw crusher works in a harsh environment with a lot of coal dust, rock dust, and moisture, the lubricant is inevitably contaminated by these impurities. Therefore, the lubricant is required to have good anti-rust, anti-corrosion, and anti-emulsification properties. When contaminated, its performance will not change too much, that is, it will be less sensitive to pollution.

3. Lubricant is less affected by temperature. The jaw crusher works in the open air. The temperature changes greatly in winter and summer. In some areas, the temperature difference between day and night is also large. Therefore, the change in lubricant viscosity with temperature is required to be small. It is necessary to avoid the oil viscosity becoming too low when the temperature is high. It cannot form a lubricating film and has no lubrication effect, and it must be avoided that the viscosity is too high when the temperature is low, making starting and operation difficult.

4. Lubricant has good flame resistance. For some machinery such as jaw crushers that are often used in mines prone to fire and explosion accidents, it is required to use lubricants (fire-resistant fluids) with good flame resistance, and flammable mineral oil cannot be used.

5. The lubricant has good sealing performance. The lubricant used in the jaw crusher should have good adaptability to the seals to avoid damage to the seals.
