Anti-vibration solutions for crushers/hammer. This is a device mixing and beating various substances (in particular cereal). Vibrations and shocks (generated by the unbalance) must be isolated by the structure with adapted antivibratory and acoustic solutions which bring an improvement in the longevity of the structures and participate in the protection of the surrounding mechanical elements.

Vibration isolation: Reliably minimize vibrations and structure-borne sound. In practically all fields of engineering, the reduction of vibration and structure-borne sound transmission is becoming increasingly important. Isolating machines, plant, components and buildings protects people and material assets and thus makes an active contribution

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
