Vibrator screen is mainly used in crushing the material after grading, simple structure, reliable performance, easy operation, ore processing equipment industry is one of the indispensable, but for various reasons, shaker torsional vibration phenomenon may occur, which would affect screening efficiency, while also causing damage to the equipment.
Firstly when vibrator screen is in the production process, due to the effect of the device by the centrifugal force generated vibration force fixed frequency, so when any of the shaker during operation of a production chain failure will affect the next production process.
Secondly, when the excitation force shaker vibration source generated deflect or shift direction, or shaker spring and damping parameters after different parts failure will result in the screen box have a "torsional vibration phenomenon," and appeared with on shaker material deviation, resonance, stagnation and other phenomena.
First, installations
1, 4 spring bearing screening machine can means harmonization of surface, whether the amount of the current austerity as the error can not exceed 5mm.
2, when the universal joint shaft means on both sides of the phase angle can, like other reason but also on the basis of a detailed screening machine status and the use of further discrimination.
Second, the design of manufacturing
1, check whether the screen frame is standard rectangular rather than a parallelogram.
2. Check the design and manufacturing process in four spring bearing screening machine whether the consolidated level surface, the choice of whether or not the same spring stiffness.
3, self-synchronization status is normal between the two vibrators.
4, both sides of the plate vibrator unified main shaft, the eccentric phase angle deputy adjustment can block consensus, since it affects the exciting force to happen whether consistent.
