Causes And Solutions For Jaw Crusher Jamming And Failure To Discharge

27/12/2024

Jaw crusher is a commonly used crushing equipment used to crush large pieces of stone and other materials into smaller particles. However, in the process of using jaw crusher, sometimes there will be problems of jamming and failure to discharge, which will cause the equipment to fail to work properly and affect production efficiency. This article will discuss the reasons for jaw crusher jamming and failure to discharge, and provide corresponding solutions.

I. Causes of jaw crusher jamming and failure to discharge

1. Material is too hard or too large: Material is too hard or too large is a common cause of jaw crusher jamming and failure to discharge. When the hardness of the material is too high or the particle size is too large, the crushing capacity of the jaw crusher is difficult to meet the crushing requirements, resulting in material accumulation in the crushing chamber, forming a jamming phenomenon.

2. Equipment design problems: Design problems of the jaw crusher may cause jamming and failure to discharge. For example, poor matching between the jaw plate and the toggle plate, incorrect dimensions of the jaw plate and the toggle plate, unreasonable position of the tooth seat, etc., may all lead to jamming and failure to discharge.

3. The transmission belt is loose or worn: The transmission belt is the power source of the jaw crusher. Its looseness or wear will affect the normal operation of the jaw crusher. When the transmission belt is loose, the driving ability of the motor will decrease, affecting the crushing effect; when the transmission belt is severely worn, it will increase the resistance during the transmission process, causing the material to accumulate in the crushing chamber, resulting in a jam.

II. Solutions to the problem of the jaw crusher jamming and not discharging

1. Strictly control the size and hardness of the feed: During the production process, the size and hardness of the feed should be strictly controlled to prevent hard or large materials from entering the crushing chamber. The feed can be preliminarily screened by setting up screening equipment to ensure that the material meets the crushing requirements.

2. Adjust the equipment design: For the jamming and non-discharging caused by equipment design problems, measures can be taken to adjust the equipment design. For example, adjust the size of the jaw plate and toggle plate, optimize the position of the tooth seat, etc., to improve the crushing effect of the equipment.

3. Keep the transmission belt tight and clean: During use, the transmission belt should be kept tight to avoid a decrease in driving capacity due to looseness; at the same time, the debris on the transmission belt should be cleaned regularly to keep it clean and smooth to reduce resistance during transmission.
