Product Overview The Vibratory Screening Feeder is an innovative dual-function unit combining precision feeding and primary screening in a single compact footprint. Designed to meet GB/T 13306-1991 and GB/T 755-2008 standards, this equipment streamlines material processing by eliminating the need for separate feeding and screening systems. Ideal for aggregates, recycled materials, and industrial raw materials, it delivers cost savings through reduced floor space requirements and energy-efficient operation.
