Abstract

The invention discloses an aggregate recovery system which comprises a fine particle collecting device (1), a coarse micro powder collecting device (2), a dust collecting device (3) and a negative pressure suction device (4). The negative pressure suction device (4) carries out negative pressure suction on the fine particle collecting device (1), the coarse micro powder collecting device (2) and the dust collecting device (3), so that fine particles in machine-made sand waste are separated when the machine-made sand waste passes through the fine particle collecting device (1), and coarse micro powder in the machine-made sand waste is separated when the machine-made sand waste passes through the coarse micro powder collecting device (2), and the machine-made sand waste after the separation is collected through the dust collecting device (3). The invention further discloses an aggregate recovery method and a sand making method. The aggregate recovery system can recover the fine particles and the coarse micro powder in the machine-made sand waste, and the grading of machine-made sand is optimized.

Description

technical field [0001] The application relates to the technical field of building material preparation, in particular to an aggregate recovery system. The application also relates to an aggregate recovery method, and also relates to a sand making equipment, which adopts the above aggregate recovery system. Background technique [0002] At present, with the depletion of natural sand resources and the gradual prohibition of mining, machine-made sand is increasingly used in construction and engineering fields to replace natural sand. The gradation of machine-made sand is an important indicator to measure the quality of machine-made sand. [0003] According to GB / T 14684-2011 "Sand for Construction", the gradation requirements of machine-made sand are divided into: 4.75~2.36mm, 2.36~1.18mm, 1.18~0.6mm, 0.6~0.3mm, 0.3~0.15mm. The typical gradation characteristics of existing machine-made sand are "big at both ends and small in the middle", with more particles with a particle siz...
