The most common types of aggregate crushers are: Jaw crushers:These crushers use a fixed jaw plate and a movable jaw to reduce the size of the feed material. They are ideal for primary crushing. Impact Crushers:Impact Crushers use a high-speed rotor and hammers to hit the incoming material and break it into smaller pieces.

Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final Product Isn't Uniform. Cone crushers do an excellent job of providing finished material that's relatively homogenous.

Abstract. Aggregate shape properties have a direct influence on the behaviour of pavement materials. The crushing process is the main factor responsible for generating these shape properties; however, there has hardly been any effort directed toward optimising the performance of pavement materials by altering the crushing …

Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
