The heavy vibrating screen esigned and manufactured by Henan Hongxing Mining Machinery is put into use in the open pit coal preparation plant in 1983 to replace the spiral screen for sculping gangue and grading the large and medium blocks, which has conducted innovations and practices for the heavy vibrating screen products. A lot of large equipments of Henan Hongxing Mining Machinery are imported from the foreign countries. The super heavy screening equipment is needed to match for the equipment imported. In 1992, Henan Hongxing Mining Machinery successfully developed the YAC-2460 super heavy vibrating screen, whose maximum feeding size can be up to 400mm with a capacity of 1000t/h.
