Blockage not only drags down efficiency but may also destroy equipment! Pre-screen impurities, wash ore to reduce moisture and stickiness, accurately adjust the belt tightness, monitor the eccentric shaft operation in real time, and install a current sensing alarm device - four steps to solve the "intestinal obstruction" of the crusher and make the production line throughput like a rainbow.

Once blockage occurs during the operation of the stone production line, the production efficiency of the equipment will be greatly reduced. In severe cases, it will cause failures and even damage the equipment. Therefore, mastering effective prevention measures and solving the blockage problem in time are of great significance to ensure smooth production and improve corporate benefits.

The crushing of materials is inseparable from the crusher. If there is a blockage during the material feeding process, the crushing capacity will be reduced and even the finished particle size of the material will be affected. How to avoid this phenomenon? Mining crushing equipment manufacturers give you tips.

1. Pre-treat the material

When the material to be crushed has high humidity and high viscosity, or contains too much unbreakable material, it will significantly increase the difficulty of crushing. At this time, pre-screening can be used to screen out unbreakable impurities; pre-washing can be carried out to reduce the moisture and viscosity of the materials. This two-pronged approach can effectively resolve the problem and allow subsequent crushing operations to proceed smoothly.

2. Adjust the tightness of the V-belt

If the V-belt is too loose, a large amount of material will not be crushed as the groove wheel rotates, and it will stagnate in the crushing chamber of the double-roll crusher, causing blockage. Therefore, it is only necessary to adjust the tightness of the V-belt.

3. Observe whether the eccentric shaft is running normally

When the eccentric shaft fixing bushing is loose, the eccentric shaft will be stuck and the crushing work cannot be carried out. Therefore, always pay attention to whether the eccentric shaft is running normally.

4. Install an alarm device

The operating current of the belt conveyor is related to the amount of material in the lower cavity. If there is a lot of material, it is easy to cause the crusher to jump and stop. Therefore, based on 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, the alarm device starts to alarm, and the feeding can be stopped in time.
