Abstract

The invention relates to a dry sand making large-sized modularized vibratory screening device and screening method for screening and classifying mixed sand formed by dry roll sand making according to different specifications of required sand. The device consists of a fixed linear vibrating screen, an upper movable linear vibrating screen, a lower movable linear vibrating screen, an upper linear vibrating screen guide rail and a lower linear vibrating screen guide rail, wherein the upper linear vibrating screen guide rail and the lower linear vibrating screen guide rail are arranged on the lower side of the fixed linear vibrating screen in sequence respectively; the upper movable linear vibrating screen and the lower movable linear vibrating screen are positioned on the upper linear vibrating screen guide rail and the lower linear vibrating screen guide rail respectively. The device and the method have the advantages that firstly the defects of difficulty and time consuming in replacement of a damaged screen of the existing fixed linear vibrating screen and complete replacement of the screen are overcome and the sand of different specifications can also be screened according to a national standard, and secondly the manufacturing of a large-sized vibrating screen is realized through the design of a multi-motion linear vibrating screen, and the gap between the fixed linear vibrating screen and a multi-layer movable linear vibrating screen is reduced.

Description

technical field [0001] The invention relates to a large-scale modular vibrating screening device and screening method for dry sand making, which can filter and classify the mixed sand formed by dry rolling sand pressing according to the required sand regardless of specifications, which belongs to the dry sand making production line Sand screening device manufacturing field. Background technique [0002] CN103433108A, titled "a dry sand making equipment and process", including jaw crusher, impact crusher, first grading screen, dry sand making machine, second grading sieve and centralized dust collection system; the production process route is, stone The stone in the warehouse is evenly sent to the jaw crusher through the feeder for the first coarse crushing, and the crushed material is transported to the impact crusher for the second fine crushing, and the crushed material enters the first classifying screen for further crushing. Classification, the sand less than 40mm is se...
