A field vibration test was conducted on the coal crusher chamber of a thermal power plant to evaluate its vibration performance. The vibration displacements and velocities of the structure, coal crusher …

Since a gas turbine is hot engine, its bearing vibration measurement cannot be done through an eddy probe system. Generally a velocity or an acceleration pick-up is used for measuring and monitoring the vibration on the body of the gas turbine. The vibration pick-ups are generally installed on the turbine's CT/GP and PT points.

where the coal enters the screen. The body of the screen is supported on a steel coil spring suspension. One or more vibration mechanisms are mounted to a steel beam that connects the sides of the screen. These vibration mechanisms, which use rotating eccentric shafts to generate vibration, are belt-driven by an electric motor.

Regarding Question 1: My experience was with vibration measurements and analysis on Raymond vertical coal Mills. That mill design had a rotating table and spring-loaded rollers. Vibration levels can be significantly affected by process conditions that are particularly related to …

A nonlinear control plant was studied based on the ball mill for coal milling at a thermal power station. The vibration parameters of the ball mill that define the quality of the milling process were analyzed. The measurement system for defining the quantity of the material in the mill during its operation is presented.

A series of measurements in the ings,same preparation plant indicated that noise due to. was the dominant noise source, whereas noise from material flow was less significant. Further showed that most of the noise due to vibration is radiated by screen body and mechanism housings. 7,8. Screen body noiseis the main source

The present study is specifically aimed at assessing the WBV exposure of 79 dumper operators engaged in two Indian opencast coal mines through vibration measurements followed by questionnaire survey. From daily frequency-weighted rms exposure A(8), it is found that dumper operators have experienced vibration levels higher than the Health ...

Vibration can be expressed in metric units (m/s 2) or units of gravitational constant "g," where 1 g = 9.81 m/s 2. An object can vibrate in two ways: free vibration and forced vibration. Free vibration occurs when an object or structure is displaced or …

Industrial crushers, cement mills, machines, textile machines, or centrifuges are typical examples for the use of active vibration control (control at the source). Vibrations and structure-borne noise due to the use of such machines can clearly be reduced with elastic support.
