The four main causes of mobile crusher blockage are: excessively fast feeding, unstable voltage, improper discharge port adjustment, and loose V-belts. Accurately troubleshoot and address the issues to ensure smooth, uninterrupted production.

Mobile crushers can malfunction for a variety of reasons and types. One common problem is blockage. Troubleshooting this requires first identifying the cause. Analysis has revealed that the main causes are the following four factors.

Factor 1: Feeding Too Fast

Mobile crushers require a consistent feed rate during operation, neither too fast nor too slow. If the feed rate is too fast, the material entering the crusher chamber will not be crushed in time, leading to blockage. To prevent this, a vibrating feeder is typically required to achieve consistent feeding.

Factor 2: Unstable or Low Voltage

The motor of a mobile crusher requires a certain voltage to operate properly. If the voltage is unstable or too low, the motor will still rotate, but the power generated will not be sufficient to crush the material in the crushing chamber, resulting in a large amount of material blocking the crushing chamber. Blockages can affect production.

Factor 3: Improper discharge port adjustment

During mobile crusher operation, slow material discharge or blockage at the discharge port can cause material obstruction, resulting in a large amount of material being trapped in the crushing chamber and causing the equipment to stop.

Factor 4: Improper V-belt tensioning

During mobile crusher operation, a V-belt transmits power to the sheaves to crush the material. When the V-belt becomes loose, it slips, rotating with the sheaves instead of driving them. This prevents the material from receiving the normal crushing force and preventing it from being crushed in the crushing chamber, leading to material blockage.
