Wash plant for aggregates is a common washing equipment in sand production line, which is widely used in mining, sand and gravel plant, building materials, chemical industry, transportation, concrete mixing station and other industries. Sand washing machinery can effectively remove the impurities covered on the surface of sand and gravel, and destroy the water vapor layer wrapped on the surface of sand. It not only has the function of efficient cleaning, but also has the function of dehydration.
Generally speaking, a set of sand washing machinery and equipment is composed of vibrating feeder, jaw crusher, sand making machine, vibrating screen, sand washing machine, belt conveyor and other equipment. Each equipment cooperates with each other to complete the sand washing operation. The types of sand washing machines include wheel sand washing machine, spiral sand washing machine, fine sand recovery machine, dehydration sand washing machine and other equipment. These equipment are widely used in various production lines.
Production process of aggregate production line:
Bulk materials are evenly sent to jaw crusher by vibration feeder for coarse crushing. Coarse crushed sand is sent to sand making machine by belt conveyor for further crushing. Only stones meeting the requirements of particle size can be sent to finished material pile by belt conveyor, while sand not meeting the requirements of particle size can be sent back to sand making machine by belt conveyor for crushing again, forming a closed circuit and multiple cycles . The grain size of finished sand can be combined according to the production needs of users. In the actual operation of aggregate production line, in order to protect the ecological environment, auxiliary dust removal equipment can be configured.
For users, the site and scale of the sand and gravel plant are the key factors to determine the sand washing scheme. If the plant area is large, appropriate fixed sand washing production line can be configured, and the fixed sand washing production line process is clear and scientific; if the plant area is small, mobile sand washing production line can be used to improve the flexibility of the plant.
