The primary function of a jaw crusher is to reduce the size of the material to a specific size range, commonly referred to as the reduction ratio. The reduction ratio is a critical factor in determining the efficiency of a jaw crusher, as it directly affects the size and capacity of the machine.
Crusher sizes There are many different crusher sizes: The first two figures indicate the diameter of the rotor. The last two figures indicate the feed opening width. For example, NP1415 has a rotor diameter of 1.4 m (55 in.) and a feed opening width of 1.5m (60 in.). NP impact crusher components The main components of the NP Impact
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).

The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction …

Crushing ratio of the whole aggregate impact crusher is large, and the discharge granularity is adjustable, which greatly simplifies the crushing process.
The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.
The inlet opening defines the overall feed-size. As a rule of thumb it is recommended that the maximum feed size is 80% of the inlet opening width. A chain curtain prevents rocks …
However, due to its high reduction ratio, the need for multiple secondary units is normally eliminated. For the recycling of concrete and asphalt, the APSE Series Primary Impact Crusher is an ideal choice to process recycled materials down to a product size of 0 – 4 inch (80% passing 2 inch) in a single pass.
Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
The impact crusher is a new and high-efficient cement crusher, with advantages of small size, simple structure, and large reduction ratio, less energy consumption, uniform practical size and flexible selectivity.The remarkable features of impact crusher is large feeding mouth, impact crusher own 1.5 times or even 2 times larger crushing cavity than that of …

High-capacity crushers have a lower reduction than slower speed but higher compression crushers. Know The Maximum Feed Size For Crushing. You cannot exceed the maximum allowable feed size for the cone crusher model. The feed size will depend on factors such as the closed side setting, eccentric throw, and head diameter.
When larger feed sizes require up to a 6:1 ratio of reduction to achieve the final product, a Triple Roll Crusher should be chosen due to the inherent design, which allows the larger feed sizes to be readily …
