The problem of crusher blocking during the operation of a large-scale gravel production line is a situation that no enterprise wants to encounter during the equipment production process. To put it simply, blocking affects the production efficiency of the equipment. In serious cases, it will cause failures and lead to equipment damage. The following is an introduction How to solve the blockage problem of crusher.

1. Pre-treat the materials

When the material to be crushed has high humidity, high viscosity, or contains a large amount of unbreakable components, pretreatment measures can be taken. Specifically, it includes: pre-screening the materials to remove oversized or unbreakable parts; pre-washing the ore to reduce moisture and viscosity. These pretreatments can significantly reduce the difficulty of material crushing and improve crushing efficiency.

2. Adjust the tightness of the V-belt

If the V-belt is loose, it will not be able to drive effectively as the groove wheel rotates, causing a large amount of material to be retained in the double-roll crusher and cause blockage problems. To solve this problem, you only need to properly adjust the tightness of the V-belt to ensure that it fits tightly against the drive wheel, thereby restoring the normal crushing function of the crusher and avoiding blockage.

3. Observe whether the eccentric shaft operates normally

When the eccentric shaft fixing bushing becomes loose, the eccentric shaft may be stuck, causing the crushing equipment to fail to work properly. To ensure the smooth progress of the crushing operation, it is necessary to pay close attention to the operating status of the eccentric shaft. Once an abnormality is found, the machine should be stopped for inspection immediately and the problem should be solved in time to prevent equipment damage or production interruption.

4. Install an alarm device

The operating current of the belt conveyor is related to the amount of material in the lower chamber. If there is too much material, it is easy to cause the crusher to stop. Therefore, according to this feature, an alarm device can be installed at the feed port of the double-roll crusher and connected to the relay. When the conveyor reaches the set current value, the relay is energized and the alarm device starts to alarm, so the feeding can be stopped in time.
