The structure and working principle between rock jaw crusher and rock impact crusher are obviously different. The working model of the jaw crusher is extrusion, and the material is crushed in the crushing cavity composed of moving jaws and fixed jaws. The impact crusher adopts the principle of impact crushing, and the material is repeatedly crushed and broken between the rotor, hammer, and counterattack.
Fixed jaw crusher can process all kinds of soft stones, but impact crusher is suitable for crushing the stone materials with small toughness and medium hardness or bellow, such as the limestone. If the raw material is very hard, it will cause great damage to the consumable parts and shorten its service life.
Finished stone materials from the jaw crusher are not ideal and the content of the needle is high. While impact crusher has good grain size and less angular shape, and its grain shape is better than that of cone crusher. Therefore, the impact crusher is usually equipped after the jaw crusher for further shaping, and they are also a common match in the crushing line.

Cone crusher uses the lamination principle to break the stone. Rolling wall movies to the broken wall constantly to extrude the stone materials between them. Impact crusher has good grain size and less angular shape. The finished products from cone crusher have more needle-like pieces and the grain shape is not good.
However, compared with the impact crusher, cone crusher has the advantages of energy saving, large output, and stable production. So the cone crusher is welcomed in the large-scale and high-yield production line.
Jaw crusher is usually used as the primary crusher in the crushing plant, while the cone crusher is used as the secondary crusher. They have a different working principle.
The jaw crusher mainly crushes the material under the function of extrusion between two jaws. Cone crusher uses the lamination principle to break the stone. Rolling wall movies to the broken wall constantly to extrude the stone materials between them.
Jaw crusher can process the stone materials with medium hardness, while the cone crusher can process the hard stones. Generally, the cone crusher can shape the stone materials better.
At first, the stone materials are delivered into the jaw crusher for coarse crushing by the feeder. Then, the materials crushed by the jaw crusher will be crushed by impact crusher or cone crusher further. Thirdly, the crushed stone materials are sent to the vibrating screen to separate the stone materials from the impact crusher or cone crusher.
If the size of finished stone materials is qualified, stone materials will be delivered to different storage piles by the conveyor belt or be transported to the working site by the truck. But if the size of stone materials is still big, stone materials will be put into the impact crusher or cone crusher for further crushing.
We not only have the HD jaw crusher, but also have the portable jaw crusher, mobile impact crusher, mobile cone crusher. With the development of Henan Fote Machinery Ltd. and the creation of crushing technology, more and more new type crushers arise, such as single cylinder hydraulic cone crusher, multi-cylinder hydraulic cone crusher, and tracked mobile crusher.
New types of mining crushers
Customers should analyze and compare with different situations when choosing the crusher machines. For example, a large-scale company often use cone crusher for their beneficiation project, while the impact crusher is suitable for the medium and small beneficiation factories.
If you want to process the viscous material, the jaw crusher and impact crusher are the better choices. It is suggested that you can choose the most economic crusher based on your comprehensive demands and site situation with the help of FTM Machinery engineers.e.
