What causes tension rods in jaw crushers to break?

Tension rods in jaw crushers can break due to excessive stress from improper settings, such as an overload of material or an incorrect tension force. Additionally, jaw crushers are subject to wear and tear from abrasive materials, which can lead to weaker tension rods.

Tension rods in jaw crushers are designed to hold the movable jaw in place and to prevent it from moving sideways or being damaged due to excessive force. These rods are subject to high levels of stress and strain during operation, and if they are not properly designed or maintained, they can break or fail.

There are several factors that can cause tension rods in jaw crushers to break, including:

  1. Improperly designed tension rods: Tension rods that are too weak or not properly sized for the crusher can fail under high stress or strain.
  2. Fatigue: Over time, repeated stress and strain can cause tension rods to weaken and eventually break.
  3. Corrosion: Corrosion can weaken tension rods, especially if they are not regularly inspected and maintained.
  4. Improper installation: If tension rods are not installed properly, they can be under too much stress and may fail prematurely.
  5. Excessive force: If a jaw crusher is operated with too much force or is used to crush hard materials, the tension rods may be subjected to excessive stress and may break.

To prevent tension rod failure, it is important to properly design, inspect, and maintain the tension rods and the overall crusher. Regular inspections and maintenance can help identify potential problems before they become serious, and proper use of the crusher can help prevent excessive force and stress on the tension rods.
