Research on Process Technological Transformation of Solid Waste Resource Reuse in a Dump
The ecological environment comprehensive treatment project of an iron mine in Qianan City,Hebei Province is to use the solid waste resources of the dump to produce building materials products.Since it was put into operation,there have been problems such as heating of the belt conveyor transmission device,the processing capacity of the coarse crushing process failing to meet the design standards,and the medium and fine crushing and sand making equipment failing to operate at full load.The most significant is the relatively low yield of building materials.Through the analysis of the problems in the process,the process transformation of the coarse crushing silo modification,the expansion of some belt conveyor motors,and the increase of magnetic separators were carried out.After the transformation,the output of building sand in-creased by 255 600 t/a,and the output of iron ore rough concentrate with total iron grade of 60%±5%in-creased by 13 800 t/a.The effect of technical transformation is remarkable.
