Technical Field

[0001] The utility model relates to the technical field of building sand and gravel material treatment, in particular to a multi-stage sorting structure for building sand and gravel materials. Background Art

[0002] Sand and gravel refers to the loose mixture of sand grains and gravel. Geologically, mineral or rock particles with a particle size of 0.074 - 2 mm are called sand, and those with a particle size greater than 2 mm are called gravel or angular gravel. Building sand and gravel materials are a commonly used material in construction projects, mainly used for the construction of concrete, roadbeds, railway ballasts, etc. During the process of crushing and processing stones in a sand and gravel production line, sand and gravel with different particle sizes will be produced. In order to improve the quality of building products, ensure the stability of products, and control costs, etc., it is necessary to screen the sand and gravel.
