Pneumatic vibrator suitable for what work

Today a lot of work completed by the vibrator. Its main application is to empty the hopper, material selection, concrete tamping and sand, soil and any other powder or small particles and a screw feed. In the electronics industry also apply vibration to detect the contact of the printed circuit board.
According vibrator energy forms and works, the vibrator can generally be divided into electric, pneumatic, hydraulic energy type, its technical form were rotary / linear / magnetic rotary / linear and rotary.
Pneumatic vibrator assistance under vibration force can carry out any type of bulk material feeding, tamping or sorting operation. In most cases, vibrations are on the gravity of "support" role. For example, due to the influence of moisture, bulk material may stick to each other in the hopper, hopper blockage. In this case, the vibration can be broken, so the material out of the hopper by gravity.
Another application is in concrete terms the vibrator. Concrete vibration is of sand and stones vibrated so that they achieve the most dense state, thus removing the middle of a bubble. In the tamping process, mainly by gravity, but the vibration will help in this regard, and can greatly improve their performance.
In both cases the vibration will reduce friction material.
Vibration not have to have a supporting role for gravity sometimes causes vibration material "bounce", and gravity feed material back to hang. By helping the linear vibrator we can bounce direction given material, and can be changed by adjusting the amplitude of the beating step.
