The vibrating screens and the inlets are connected by the conveyor belt and fixed on the beam–plate of the second and third floors The vibration of the secondand thirdfloor beam–plate structures vibrates violently when the working frequency of the vibrating screens is 1428 Hz The strong vibration could bring some threat to the1 Introduction Coal is one of the most important fossil energy sources in the world [1], [2], [3]In 2019, coal consumption accounted for 577% of the total national energy consumption in China [4]Although coal has greatly contributed to the development of the world economy and industrial production, smoke and harmful gases formed due to Variable elliptical vibrating screen: Particles kinematics and
In order to reduce the excessive vibration responses of a reinforced concrete frame structure induced by several vibrating screens working simultaneously, field vibration monitoring and some vibration reduction measures are carried out The results of field vibration monitoring show that the maximum vertical vibration of the structure The “Technical code for the design of civil structure of fossilfired power plant” (DL 5022–2012) stipulates that if the vibrationisolation efficiency of a spring vibrationisolated foundation is greater than or equal to 90%, the support structure below the vibration isolation device of a coal crusher does not require dynamic calculationVibration Test and Shock Absorption of Coal Crusher Chambers
Screening techniques have been widely deployed in industrial production for the sizeseparation of granular materials such as coal The elliptical vibrating screen has been regarded as an excellent screening apparatus in terms of its high screening efficiency and large processing capacity However, its fundamental mechanisms and operational In improving dewatering performance, Dong et al 1,2 developed a vibratingdewatering screen with a unique structure that uses side plate beam excitation Shi 3 studied the highfrequency coal slime vibratingdewatering screen, and analyzed the parameters selection method and structural design characteristics of the machine In Study on screening performance and parameter optimization
