[0002] Sand and gravel production refers to the production of sand and gravel products that meet specific specifications from natural ores or stones through mining, crushing, screening and other processes. Sand and gravel are widely used in construction, roads, railways, water conservancy and other fields, and are an important part of building materials. The main steps of sand and gravel production include: Mining: According to needs, select suitable mines or quarries for sand and gravel mining. Attention should be paid to environmental protection and sustainable use of resources during the mining process. Crushing: Crushing the raw stones obtained from mining, usually using equipment such as crushers or jaw crushers to crush the raw stones into smaller particles. Screening: The crushed stones are screened through screening equipment to separate sand and gravel particles of different specifications as needed. Washing: Wash the sand and gravel to remove soil, dust and other impurities in them to improve the quality and purity of the sand and gravel. Sand and gravel processing: According to needs, the sand and gravel are further processed, such as shaping, grinding, sintering, etc., to meet specific application requirements. Storage and transportation: The produced sand and gravel products are stored and packaged, and then transported to users or construction sites by means of transportation (such as trucks, railways, etc.).
