Vibration isolators are used to reduce the transmission of noise, shock, and vibration produced by mechanical, industrial or process equipment into or within a building structure. To isolate or reduce the transmission of noise and vibration from engine or mechanical equipment; like as metal stamping, punch, rock crusher, marine, mining

The active vibration isolation system essentially uses a feedback or a feedforward circuit which consists of an accelerometer, a controller, and an electromagnetic transducer in addition to a mass, spring and damper. Since the passive vibration isolation system has a resonant frequency fn, it can isolate a vibration over square root of 2 times

Cone crushers wobble their liners about a vertical shaft and can impart a significant vibration to the surrounding structure. Most structural-vibration problems like you are describing occur because the horizontal forces and horizontal structural stiffnesses are underestimated. High speed vertical shaft impactor crushers are seldom a problem

The key feature of ‘constrained vibration’ is that the amplitude of the circular vibration is predetermined and invariable (factory set) regardless of the weight of the material. The fixed frame is equipped with special rubber pads which totally isolate the supporting structures from vibrations.

Problem The primary crusher structure at an iron ore facility was exhibiting consistent, unacceptably high vibration levels during operation. The primary crusher operated at approximately 4Hz and was fed from a vibratory feeder operating at approximately 1000tph, at a frequency of 800-1000rpm. Deacon Engineers were contracted to come with a solution and necessary modifications to

structural steel buildings, the crushers generate a considerable amount of vibration. Transmitted to the structure, this vibration can result in structural damage over a period of years. Typical coal crushers, driven by up to 1,000 horsepower (750 kW) motors, can have a total system weight of up to 50 tons (45.5 tonnes). At speeds of 450 to 900

The most important part of any vibration isolation project is fully decoupling the vibration source from the structure. In this case we are isolating the mill and power drill from the shelf. To float the mill above the shelf I used 3/4" diameter Isolate IT Sorbothane hemispheres . 4 of these gave me a nice stable base to set the mill on.
