Different production lines use different types of clinker crushers

This article mainly summarizes the problems and solutions in the production process of the hammer crusher. In order to further reduce the impact load of the axial movement of the baffles at both ends of the hammer shaft, and prevent the hammer shaft from axial movement, the welding iron on the hammer plate can prevent the hammer head from falling off due to the displacement of the hammer shaft.Baffles are added at both ends of the hammer shaft. 

There are two reasons: one is that small clinker particles enter the seal, causing the graphite packing to wear and lose its sealing; the other is that the number of windings of the graphite packing is too few, the resilience is poor, and the oil storage is small. In the production, the main problem of the hammer crusher is that the casing and the rotor sealing device are easily damaged, resulting in more material leakage, heating of the bearing, and large vibration of the hammer crusher body. 

Different production lines use different types of clinker crushers, such as hammer crushers, roller crushers, and so on. The hammer head is broken due to poor casting quality; the hammer shaft design is unreasonable, causing the hammer shaft to break easily, causing the hammer head to fall off; the shaft sleeve positioning bolts on the hammer shaft are easy to shear, causing the hammer shaft to move outwards, causing the hammer head to fall off.In the production of new dry-process cement, the grate cooler is one of the key equipment. 

The shell and rotor seals of the hammer crusher are easily damaged The casing of the crusher and the rotor are sealed with a gland packing sealing device. The packing adopts graphite packing, which is easy to wear. Solution: During the maintenance period, the original gland packing sealing device is transformed into an axial labyrinth sealing device to strengthen the sealing effect, increase the service life of the sealing device, China Wheel Bearing and completely solve the problem of material leakage in the crusher shell. These factors cause rotor vibration, which has a great impact on maintaining the balance of the hammer crusher rotor. 

The middle of the hammer shaft is no longer drilled and replaced with a smooth shaft. Solution: Transform the hammer shaft of the crusher. If the lubrication is poor or the graphite packing is pressed too tightly, the oil film will be interrupted, causing dry friction between the graphite packing and the rotor, causing the graphite packing to be damaged and lose its sealing
