Abstract

Addressing issues such as increased crushing force and energy consumption caused by the formation of force chains within the crushing zone during the operation of roller crushers, a new roller-type vibrating crusher that utilizes vibration to eliminate or reduce the formation of stress chains is proposed. Data is used to illustrate the superiority of this new roller-type vibration crusher, while demonstrating the methodology and support provided by EDEM for solving similar problems. Force reduction: The secondary crushing roller experienced a 57.27% reduction in load compared to high-pressure grinding rolls. The following results were obtained through simulation: Kinetic enhancement: Particle velocity increased by 28.5%, accompanied by a 23.34% rise in crushing ratio.Energy efficiency: Specific energy consumption decreased by 36.83%, while unit productivity surged by 58.3%.

Keywords: New Roller-Type Vibrating Crusher; EDEM; High-Pressure Roller Mill; Comparative Analysis.
