4 Things You Must Know about the Lubrication of Jaw Crushers

by Ivy Z. Mining Equipment Sales

Jaw crusher is a commonly used crushing equipment. We all know that its working environment and material characteristics have a certain impact on the service life of the equipment. Therefore, the maintenance work during the operation of the jaw crusher must be carried out in strict accordance with the operation process, so that its life can be longer.

As the primary crushing equipment for various ores, the jaw crusher requires the operator to have a good operating ability. In work, how to choose to add grease is a very important operation, which is one of the matters that the operator must pay attention to.

1. The choice of lubricating oil

The working environment of jaw crusher equipment is different, so different lubricants need to be selected.

  • In summer, the outdoor temperature is relatively high, so you can choose No. 70 machine oil;
  • While in winter, the outdoor temperature is low and choose No. 40 machine oil.
  • When the jaw crusher needs continuous work, there is a heating device in winter, which can preheat the lubricating oil, and when the ambient temperature in summer is not too high, you can use No. 50 engine oil as lubricating oil.

2. Way of lubrication

Because the bearings and eccentric shafts of large and medium-sized jaw crushers are lubricated under pressure, when the oil pump fails, the jaw crusher needs 15-20 minutes of swing power to stop. Therefore, a hand-pressure oil pump is required to provide oil to the bearings to keep lubrication and prevent accidents of burning the bearing.

3. Lubrication time

The lubrication parts of the jaw crusher are different, so the lubrication requirements are also different. There are differences in terms of time.

For example, there is no oil return device for the lubrication of the bearing of the movable jaw suspension shaft and the elbow of the thrust plate of the jaw crusher, so intermittent grease is required.

However, the bearing of the small jaw crusher motor jaw suspension shaft adopts the way of adding lubricating oil to the oil cup, so it can be oiled once in 30-40 min. The elbow of the thrust plate is lubricated with thick oil, which needs to be lubricated every 3-4h.

4. Temperature of lubrication

We should also pay attention to the temperature of the lubricating oil of the jaw crusher. In the use of the thin oil system of the jaw crusher, the temperature of the return oil should not exceed 60 degrees. When the temperature is too high, we need to adjust the oil valve to control the oil flow or use water cooling to reduce the temperature. Only in this way can the production work be guaranteed.
