How to do high-quality sand and gravel aggregate processing?
Sand and gravel aggregates account for 70% of the concrete volume and 80% of the mass. Doing a good job of concrete machine-made sand and gravel aggregate can not only meet the high-standard concrete production requirements, improve the quality and performance of concrete products, reduce the loss of concrete slump, and reduce Fine sand: The fineness modulus is 2.2-1.6, and the average particle size is 0.35-0.25mm. Extra fine sand: The fineness modulus is 1.5-0.7, and the average particle size is below 0.25mm. Natural sand: Rock particles with a particle size below 5mm, formed by natural conditions (mainly rock weathering), are called natural sand.Manufactured Sand What Is It and How to Make It
