What is the reason for intermittent vibration after the sand making machine starts?

There is such a phenomenon: at a certain time, each time the sand making machine is started, the machine will have intermittent shaking; sometimes it is after the sand making machine starts. The body shakes more when it starts running, and it shakes after ten minutes. Gradually become smaller to disappear. Do you know what the reason is? The following is an analysis of SBM for you.

First, the belt feeder of the sand making machine has a deviation of the feeding angle

If the feeding angle design is unreasonable, the material will be concentrated into one side of the sand making machine, causing one side of the crushing chamber to be subjected to a large force and the other side to be less stressed, causing the machine to shake. In addition, this problem can occur when the feeding is uneven.

Solution: We need to adjust the feeding angle of the belt conveyor to control the conveying amount to achieve uniform conveying of materials.

Second, the central shaft bearing of the sand making machine has one-sided wear

The sand crusher crushes the material mainly by the high-speed rotation of the central rotor, so that the material can be crushed in the crushing chamber. If the bearing seal is not good, after entering the dust, long-term operation will lead to one-side wear of the bearing connected to the rotor. Therefore, when the rotor rotates at a high speed, the center of gravity of the machine is unstable, causing intermittent vibration. The initial wear is small and the feeling is not obvious. If it is not repaired on time, it will cause serious problems such as spindle breakage.

Solution: Regularly check the spindle cleanliness and fill the lubricant regularly. Be sure to idle for at least 5 minutes before turning it on to observe the device. If the swing is severe, it should be repaired and replaced immediately.
