The original vibrating screen was YA2160 circular vibrating screen, with thin screen surface, low screening efficiency, high failure rate of equipment, three-phase universal shaft connection was used to reduce horizontal force of vibrating screen, eccentric block structure reduced vibration offset, T-iron structure screen increased the screening capacity of the vibrating screen, springs replacing rubber springs met the needs of changes in geological conditions of coal mines, providing guarantee for the output and quality of the procution.
