Crusher original two-way gapping technology, when the hammer wear, the gap between the liner and the hammer will become larger, this time the size of the material will become larger, then adjust the position of the hammer to make it narrow the gap to ensure The size of the material being discharged. The use of this technique allows the use of three hammerheads at the top of a hammer.
The crusher is a very good mechanical equipment. Even the best mechanical equipment will have different failures. Then let's take a look at the general breakdown of the crushers.
1. The rotor of the motor and the rotor of the crusher do not have the same center of mind. The position of the motor can be moved to the right or left, or a pad can be added at the bottom of the motor to adjust the concentricity of the two rotors.
2, the crushing chamber vibration is relatively large, the reason is that the joint coupling and the rotor is not concentric or flat inside the rotor is not uniform, when the hammer is uneven, the hammer must be re-selected, so that the error of the hammer is less than 5G.
3. The anchor bolts of the crusher system are loose or the foundation is not firm. When installing or repairing, the anchor bolts should be evenly tightened, and the shock absorber should be installed between the foot and the crusher to reduce the vibration.
4, to regularly check whether the hammer broken, the crush room is hard debris, which will cause the rotor to rotate the imbalance. If abnormal sound occurs during operation, we shall immediately stop the inspection and find out the reason for technical processing.
The pressure switch of the crusher can protect the crusher under the condition of insufficient oil pressure. If the oil supply pressure is reduced to the low working pressure of the crusher to F, the pressure switch will act, and the alarm signal and the mechanical parking interlock device connected with the pressure switch will Remind the operator that all pressure switches are standard components on all crushers.
The crusher operates under normal conditions with one oil pump and one spare. When the system reduces the pressure for some reason and needs to increase the oil supply, the pressure switch will control the stock pump to rise automatically when the oil pressure is lower than a certain pressure, and supply oil to the working pump at the same time until the pressure returns to normal and the standby pump stops automatically. . The abrasion of the main part of the crusher or its contact mark can truly reflect its stress condition and reflect the impact of the inspection and installation quality on it.
