  • AIR CLASSIFIER Air Classifier for Crushed Sand

    Sand classification: Classification is a process where aggregate producers remove excess ultra-fines from the sand. Sand classification is usually done by washing the aggregate with large quantities of water to separate ultra-fines; this process is known as WET CLASSIFICATION.air classifier for crushed sand,Sand production with VSI crushing and air classification · There are several types of static air classifiers available, namely Gravitational (G), Gravitational-Inertial (GI) and Centrifugal (C), and the type used will depend on the desired cut-size (Aslaksen Aasly et al., 2014).The most simple static air classifier is of the G type, see principle in Fig. 1.In a simplified way the process

    Sep 10, 2015· Washing and classifying also may be used in processing manufactured sand. The crushing process creates a significant amount of “fines,” which are undersized fine particles that pass through the smallest screen openings (which are measured by mesh sizes). The minus-#100 and minus-#200 mesh fines require washing to be removed.ENGINEERING CLASSIFICATION AND DESCRIPTION OF SOIL,crushed rock, and other materials if done according to little or no strength when air-dry is a silt.
