A wide variety of vibrating screens are operated in the raw material processing and aggregate industries. Vibrating screen is a common equipment in mining machinery and equipment, its vibration is mainly generated by the exciter to achieve, and the use of the exciter working conditions are harsh, and with strong vibration impact …
Importance of "Throw" and "G" Force "Throw" is the term used by vibrating screen designers denoting the distance that a vibrating screen travels during its operating motion. The term is also referred to as "stroke". For a straight line motion screen the "throw" is the distance between the extremities of motion.
Hoberock L pointed out that the flow of drilling fluid on the screen is an incompressible, spatial open-channel flow with a grid at the bottom. Due to the periodic motion of the screen on the vibrating screen, the flow of drilling fluid on the screen is a function of both position and space (Hoberock, 1981). Koo. J.
The dynamic response of the vibrating screen has a great impact on the screening efficiency and fatigue life of the structures. For the conventional dynamic design, the consideration of the influence of load weight on dynamic response is lacking. So, in this paper, taking a very common vibrating screen used in tunnel construction as an …

What are vibrating screens and which are its main applications for use. Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.
