The invention discloses a machine-made-sand powder selecting device structurally comprising a feeding box and a dispersing area which are communicated with each other. The feeding box is positioned above the dispersing area, a feeding port is arranged at the top end of the feeding box, a transverse stirring screw is arranged between the feeding box and the dispersing area, and one end of the stirring screw extends out of the feeding box and is connected with a motor; multiple inclined retaining plates are distributed on one side face of the dispersing area, an air inlet is formed between each two adjacent retaining plates, and an air outlet is arranged on a side face, opposite to the retaining plates, of the dispersing area and connected with an air draft device. By the machine-made-sand powder selecting device, the defect that machine-made sand produced by existing sand making equipment is high in powder content and unreasonable in proportion can be improved. The machine-made-sand powder selecting machine is environment friendly and energy saving, and most effective utilization of machine-made sand is realized.
Description
technical field [0001] The invention relates to a sand making device, in particular to a machine-made sand powder selection device. Background technique [0002] Today's China is in the rising period of development. In the country's "Twelfth Five-Year Plan", the construction industry will still be a pillar industry of the national economy and still attracts attention. Urban construction, railway highway construction and urban rail construction in the construction industry will still be in a period of continuous and stable development in the next 10-20 years. The current huge demand for sand in the construction industry, the depletion of resources such as natural sand and river sand, and the technical problems in the application of sea sand, etc., based on the above factors, this brings broad development prospects for machine-made sand. [0003] Manufactured sand refers to sand that is processed by sand making machines and other auxiliary equipment and meets certain requirem...
