Description

Broken sieving mechanism of recycled concrete

Technical Field

The utility model relates to the technical field of concrete crushing, in particular to a recycled concrete crushing and screening device.

Background

The regenerated concrete is prepared by crushing, cleaning and grading waste concrete blocks, mixing the crushed, cleaned and graded waste concrete blocks with a grading agent according to a certain proportion, partially or completely replacing natural aggregates such as sand stones and the like, and adding cement, water and the like. The recycled concrete can be combined into aggregates in the following cases: all aggregates are regenerated aggregates; the coarse aggregate is regenerated aggregate, and the fine aggregate is natural sand; the coarse aggregate is natural gravel or cobble, and the fine aggregate is regenerated aggregate; the reclaimed aggregate replaces part of the coarse aggregate or the fine aggregate. The regenerated aggregate comprises a small amount of stones separated from mortar, a small amount of stones partially wrapping the mortar and a small amount of independent agglomerated cement mortar. The surface of cement mortar is rough, the edges and corners are more, and a large number of fine cracks appear in the aggregate in the concrete construction damage and aggregate production processes, so that the porosity of the regenerated aggregate is high, and the apparent density and the bulk density are reduced.
