Conical Mounts. Conical mounts also known as cone mounts isolate shock, motion and vibration in all planes (x,y,z) and if necessary with different loads in each direction to ensure the optimum isolation throughout a wide range of frequencies. Conical mounts have a high load carrying capacity within a compact size that assures a stable solution and …

This article deals with vibration analysis of clamped (C–C) and freely supported (Fs–Fs), truncated and complete conical shells on elastic foundations with continuously graded volume fraction. The functionally graded material (FGM) properties are assumed to vary continuously through the thickness of the conical shell. First, the basic …
Shear mounts are used for heavy equipment such as compactors, hammers for excavators, crushers and generators. The parts in shear mounts dampen extreme shocks, low frequencies and machine noises. …

A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.
vibration levels, which ultimately leads to interruption of crusher operation. Coal crushers in power plants are nor-mally elevated in the structure. A proper conventional foundation design demands a thorough dynamic analysis of the foun-dation, including the substructure, soil properties and, where applicable, piles.
