Abstract
Description
Technical Field
[0001] The utility model relates to a sand washing, screening and crushing device. Background Art
[0002] With the advancement of urbanization, the demand for sand is increasing. At present, construction waste is often collected and processed into building recycled bricks. Construction waste sand is generally washed by sand washing machine to remove impurities covering the surface of sand and gravel, and at the same time destroy the water vapor layer covering the sand particles to facilitate dehydration and achieve efficient sand washing and cleaning. However, since the sand is mixed with waste materials of different sizes, it is necessary to roughly screen it before sand washing to screen out too large sand to avoid affecting the subsequent sand washing work of the sand washing machine. After the larger sand and gravel are screened out, the traditional method is generally to manually crush the large sand and gravel with a crushing tool, and then wash the crushed small sand and gravel. This method is time-consuming, labor-intensive and inefficient. Utility Model Content
