Abstract: The dry method is adopted by the powder contractor of Santan aggregate processing system in Jinping I Hydropower Station. Compared with the conventional sand manufacturing method by washing, the water consumption of the dry method is reduced significantly. So, the water supply system and sewage treatment facilities are not necessary because there is no need for the treatment of a large amount of waste water during the manufacturing process. The spray water for dust suppression, and water for cleaning and washing can be recycled after simple treatment, which can save resources and protect environment. The procedures, problems and corresponding solutions in the manufacturing process are introduced.
