Inertial vibrating screens operating in resonance and post-resonance mode represent a class of screens that present a series of advantages: simple construction and maintenance, high flow rates, low energy consumption, low level of vibrations transmitted to the building in which they are located, high screening efficiency.
A vibrating screen is widely used in raw coal screening, but intensive resonance in the startup and shutdown stages shortens the service life of the vibrating screen and generates vibration damage to surrounding buildings. Therefore, we designed a novel vibration isolator based on a magnetorheological damper, aiming to improve the …

Large vibrating screen is the key equipment to improve the clean and efficient utilization of coal. In recent years, various advanced design techniques and methods have been energetically explored and applied into developing high-performance and long-life vibrating screen.
Traditional vibrating system has the characteristics of poor isolation ability and easy to plug the screen. To enhance vibration isolation ability and probability of screen plugging during the operation of vibrating screens, an anti-resonance system with dual-motor and double-frequency actuation is proposed.
The list includes manufacturers and suppliers of sensor-based mineral sorters, intelligent screens for mining applications, advanced vibrating conveyors, electromagnetic separators, as well as for ore, concentrates and by-product samplers.
Traditional vibrating screen usually adopts the linear centralized excitation mode, which causes the difficulty in particles loosening and low screening efficiency. The variable elliptical vibrating screen (VEVS) trajectory is regulated to adapt the material mass along the direction of the screen length, improving the particles distribution as ...
