A comparison of jaw crushers with the same capacity reveals that doubletoggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly singletoggle jaw crushers are used in the aggregate sector, while doubletoggle jaw crushers are used mostly for crushing very hard and highly abrasive materials.
The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure ).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure (a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).

· Impact Crushers are available in stationary, track, and portable configurations meeting any demand for any of these industries. Although Impact Crushers generally have a higher operating cost than other crushers, they tend to produce a more uniform particle shape (cubical) which is desirable and produce more fines for hot asphalt producers.

Applying the crushing force by rolling the nut breaks flats and gives a product that is more "cubic" than the jaw crusher. – The largestscale equipment can treat a flow with the magnitude of 4,000 − 1. – With a production rate and flow that are equal, the power consumed by a gyratory crusher is similar to a jaw crusher.
The cone rock crusher can crush highhardness stones such as basalt, granite, river pebble, tuff, volcanic rock and other rocks; while the impact rock crusher can crush lowhardness stones such as limestone and bluestone. After secondary crushing, 12/13 cm stones can be directly produced. Fine crushing Sand making machine.
C Series jaw crushers are the most productive and costefficient jaw crushers for any primary crushing appliion. C Series jaw crushers were originally developed to crush the hardest ores and rocks so they perform extremely well also in less demanding appliions, such as soft rock, recycling and slag. Benefits
