Vibrational Readings are performed by picking up Your Vibration through the use of a pendulum. Using the pendulum to pick up these vibrations is a very advanced skill and requires a great deal of practice and mastery. The skill of using the pendulum to get certain answers is also called dowsing, or divining.

This is accomplished internally by modern blasting seismographs. In close proximity to the blast, body waves dominate. As the distance from the blast increases, the body waves dissipate faster than the surface waves. As the surface waves become the dominant motion, the dominant vibration frequencies will be lower.

The common causes of abnormal vibration of cone crusher as follows. 1. Overfeeding or uneven feeding. If feed too much materials, and exceeds the load of the cone crusher, the equipment will not be able to crush the materials in the crushing chamber in time, thus causing the accumulation of materials and producing abnormal vibration.

As a result bearing manufacturers have developed vibration tests as an effective method for measuring quality. A common approach is to mount the bearing on a quiet running spindle and measure the radial velocity at a point on the bearing's outer ring in three frequency bands, 50-300, 300-1800 and 1800-10000Hz.

The crusher is a kind of a machine which uses a metal surface to crumble materials into small fractional pieces (Fig. 1). During this process, as well as during entering material stream into the crusher, a lot of impacts/shocks appear. They are present in vibration signal acquired from the bearing's housing.

During the installation of the hammer crusher, the installation bearing of the main machine and the motor must be the same bearing. Otherwise, when the crusher works, the motor will not directly drive the main machine, resulting in large vibration amplitude of the equipment as a whole. 3. Deep cavity rotor imbalance.
