Abstract

The invention discloses a mining and separating method for riverway dredged materials and belongs to the technical field of environmental protection engineering and building material collection. The mining and separating method takes the riverway dredged materials as raw materials and comprises the following steps that S01, the raw materials are pumped out of a riverway by utilizing a sand pump and are conveyed to a floating body through a pipeline; S02, natural sand and stones are separated through vibrating screens, and the natural sand is conveyed to a sand pit; S03, the stones are separated into large-particle stones with the partical size being larger than 4 cm and small-particle stones with the partical size being less than and equal to 4 cm after being screened; S04, the large-particle stones and the small-particle stones are conveyed to a sand making machine to be prepared into sand after being crushed correspondingly, and then the sand is conveyed to the sand pit; and S05, thesand inside the sand pit is conveyed to a sand field by utilizing the sand pump. By means of the mining and separating method for the riverway dredged materials, the natural sand and the machine-madesand are obtained by mining and separating the riverway dredged materials, the natural sand is fine and smooth in hand feeling and large in bearing capacity and is a good building material, the machine-made sand of different partical sizes can be prepared, and the natural sand and the machine-made sand both can be used in highway, railway, hydropower, metallurgy and other industries.
