Rust is prone to occur on steel surfaces when both water and oxygen are present. Rust is a specific type of corrosion that occurs on steel surfaces. Rust causes millions of dollars in damage annually, costing industries a huge amount of money. Xinshengrun, a crusher equipment manufacturer, reminds users that rust on crushers can lead to production stoppages, reduced output, production waste, huge repair costs, premature equipment replacement, and even personal safety hazards. To prevent rust on your crushers, Xinshengrun, a professional crusher manufacturer, advises users to take the following protective measures:

1. During storage or seasonal shutdowns, run the crusher for 5 minutes once a month to ensure proper bearing lubrication. If the crusher cannot be operated during storage, manually rotate the flywheel 3-4 times to ensure proper bearing lubrication. Add grease to the bearings if necessary. (Contact us for assistance if the flywheel and/or eccentric shaft have been removed).

2. If the flywheel has been removed from the eccentric shaft, the contact surfaces between the flywheel and the shaft should be coated with a corrosion inhibitor.

3. If the moving jaw has been removed from the frame, apply sufficient grease to the seals to prevent debris from entering the bearing housings. The bearing housing contact surfaces on the frame, the toggle plate contact surfaces, and the tie rod holes (if applicable) should also be coated with a corrosion inhibitor.

4. The crusher and its removed parts should be stored on a stable support to prevent contact with the ground.

5. When the crusher is removed from storage, the paint must be inspected and repaired as needed. Before assembling the crusher, the corrosion inhibitor should be removed from all contact surfaces.

Xinshengrun reminds users that the above protective measures are necessary; otherwise, moisture condensation will cause corrosion at the contact points between the bearing rollers and the inner and outer rings, breaking the rollers and the highly polished surfaces of the inner and outer rings. When the crusher moves and operates under load, bearings that are not properly lubricated will quickly become rough, leading to premature bearing failure.
