Spring Support of Mills and Crushers
systems for vibration isolation of coal mills. These systems are not only used in almost all of Germany's power plants, but also in many other power stations and industries throughout the world. Spring support enables much smaller and more compact mill foundations to be used than the conventional massive ones that were previously considered
An integrated load-bearing and vibration-isolation …
The local resonance unit proposed in this paper is shown in Fig. 1 (a) and (b). Each cell consisted of a mass block, a thin plate and two frames, which could be simplified as a damped "mass-spring-mass" system, shown in Fig. 1 (c). In the unit cell, the block provided inner mass M 1, the thin plate provided stiffness as a special spring K, and the …
