The motor shaft and the rotor shaft are not concentric? Realign immediately! Bearing damage causes severe vibration? Regular inspection and replacement is the key. Control the feed specifications, eliminate large particles and foreign matter, adjust the rotor components synchronously, strictly control the weight difference within 5g, quickly clear the blockage, and ensure the efficient operation of the equipment.

The reasons for the vibration of the sand making machine rotor are as follows:

1. The motor shaft and the rotor shaft are not concentric

The solution is to realign. After checking and installing, make sure that the motor shaft and the rotor shaft are concentric.

2. Rotor bearing damage

The rotor vibrates violently, it is likely that the bearing clearance exceeds the limit or the bearing is damaged. In this case, new bearings need to be replaced in time. In order to avoid delaying production due to bearing problems, the bearings should be checked regularly during the use of the equipment so as to detect and solve the problem in time.

3. Unbalanced rotor

Other parts on the rotor are unbalanced, which will cause the rotor to be unbalanced, thereby causing vibration. At this time, it is necessary to carefully check one by one and balance the rotor. Take the hammers as an example. When changing the face and turning around, all the hammers in the crusher should be operated synchronously to prevent imbalance. During installation, the weight difference between the two sets of hammers must be controlled within 5g.

4. Material blockage

Once material blockage occurs, it must be cleared immediately. In order to prevent material blockage from causing equipment vibration, the feed specifications must be strictly controlled to prevent large particles and unbreakable foreign matter from entering the crusher. At the same time, pay close attention to the moisture content of the material. If the moisture content is too high, it is easy to stick together in the crusher and adhere to the inner wall, causing blockage, so it is necessary to pay attention to the moisture content of the feed.
