Methods reducing artificial vibrating to minimum

In the course of work, it inevitably will shake for various reasons. If long-term vibration will cause the loosening of the screws and other parts or even fall off, which is the reason why we emphasize the need to be tested and regular maintenance to equipment. How can we reduce the the Sand maker shock? I will tell you some methods.
 
1 Spiral wire rope isolator. As a damping element, the wire rope, with a low frequency ofthe variable parameters of the high frequency and low stiffness of the large dampingperformance, which can effectively reduce body vibration. Compared with the traditionalrubber vibration source, anti-oil, anti-corrosion, anti-temperature, high temperature resistance, aging resistance as well as the advantages of small size, isolation effectdepends primarily on its nonlinear hysteresis characteristics.
2, hydraulic isolation. The hydraulic support system is one of the structure of conventional rubber bearing with hydraulic damping, can provide larger damping in the low frequency range, large amplitude vibration play a role in the rapid decay of the engine in the high frequencies with low dynamic stiffness can effectively reduce cab vibration and dry sound.
3, the rubber isolator. Conventional engine with elastic supports to reduce vibrationisolation mounting structure is simple, low cost, reliable performance. Rubber bearingsare generally mounted on the frame, the force is divided into the compression type, shearand compression and shear complex.
 Reverse the action principle is reversed in the past the solution to the problem or operating. One of the methods of this principle is to allow the movement of raw materials to be crushed, so that the hammer stationary, jet mill, this crushing principle, but the principle for the cereal raw materials, can reduce energy consumption to be studied.
Mechanical vibration principle is to make the instigation of the object in vibration situation or increase its vibration frequency, even up to the ultrasound. The principle prompts us to increase the mechanical vibration in the grinder, so that the crushing process in a dynamic state. Vibration can be crushed parts, sieve plate, rack, and combinations thereof. Grinder in a state of vibration, vibration mill is an example of.
Hammer crusher, of which grinding parts in the vibration state, will surely be able to improve the grinding efficiency to reduce energy consumption. But it still needs research and testing about how to take specific implementation.
Another example is the hammer mill sieve vibration can improve the rate of sifting to reduce the crush to reduce energy consumption, this principle has been successfully applied to ultra Deng aid: use of TRIZ hammer mill, horizontal wide vibrating screen hammer smash on machine products.
