Description

technical field [0001] The invention relates to a construction device, in particular to a high-efficiency classification, screening and cleaning device for construction sand and gravel. Background technique [0002] Because of its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. With the requirements of infrastructure construction technology and the development of high technology, there are higher requirements for the quantity and quality of sand and gravel. Sand and gravel are loose materials, but their particles are generally hard and chemically stable in the surface environment. For sandstone, its weathering resistance is generally strong, especially the silicified quartz sandstone, whose hardness exceeds that of granite. Sand and gravel are the basic materials in national economic construction...

AI Technical Summary

Problems solved by technology

It has different effects on sand and gravel of different sizes. The existing sand and gravel screening work is inefficient and difficult to meet the needs of increasingly prosperous production and life.
