Crushers are machines used to reduce the size of rocks, stones and ore. They are often utilized in aggregates production, construction material recycling and in mining operations. [1] There are four traditional types of crushers in materials engineering. They are known as jaw crushers, gyratory crushers, cone crushers and roll crushers.
Jaw Crushers. Jaw crushers consist of a rectangular frame with a fixed jaw plate and a jaw stock carrying the moving jaw. The moving jaw swings toward the fixed jaw in the forward stroke, the material is crushed, and …
Double toggle jaw crushers use only pressure (less friction) to break large and hard materials. Single Toggle – Overhead Eccentric Movement. Single toggle jaw crushers have grown quite popular over the past few years. Compared to the double toggle ones, the primary downside of single toggle jaw crushers is that their feed capacity was …
Jaw crushers are sometimes also referred to as "rock breakers," which speaks to their brute force. They are almost exclusively used as primary crushers because they excel at breaking up...
2. May be used where classifying is not practical. 3. May be used where control of product size is not important. 4. The use of rod mills will produce an ideal fine feed for ball mills. 5. May be used where classifier dilutuion would be objectionable. Advantages of closed circuit grinding. 1. Provides a close control of finished product size. 2.
