In many cases, initial crushing stages are followed by further milling stages using e.g. ball mills etc. Crusher Types There are three common crushers used at mining and processing plants: Gyratory Crushers; Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers.
Jaw, cone, and gyratory crushers are used for primary crushing, while hammer mills, ball mills, and SAG mills are used for secondary and tertiary grinding. Screening and Classification Equipment: Separates the crushed and ground material based on particle size. Vibrating screens, hydrocyclones, and spiral classifiers are commonly used.
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
