Research on Energy-saving and Environmentally Friendly Optimization of Building Sand and Gravel Screening Devices

Abstract

Sand and gravel are the largest and irreplaceable materials in China's infrastructure construction. Sand and gravel aggregates are the main components of concrete. To ensure the quality of concrete, a large amount of sand and gravel needs to be screened on-site using screening devices. However, existing screening devices cannot change different screening modes according to the quantities of materials, leading to high energy consumption. Additionally, a significant amount of smoke and dust is generated at the feed inlet during screening, which affects the construction environment. This paper aims to design an environmentally friendly and energy-saving sand and gravel screening device to address these issues.
