In mining and quarry crushing applications, the size, hardness and output of the raw materials determine the type and model of the crusher. In aggregate processing equipment, the most common crushing equipment is jaw crusher and impact crusher. What is the difference between these two types of crushing equipment?
Jaw crushers will perform better in medium to high compressive strength applications and abrasive applications. It crushes stones through compression and squeezing, which can easily destroy the stable structure of hard rock. Jaw crushers are often used in primary crushing applications.
Impact crushers are usually used for applications where the stone is softer, has a lower density and less abrasive. The high-speed rotating rotor throws the stone into the impact toggles, and the impact energy generated by the rotor breaks the rock along its natural fracture line. As secondary crushers, they are often used behind jaw crushers to create final products that meet the standards.
Jaw crushers are compression crushers, and wear-resistant parts must have high wear resistance. Therefore, the jaw plate of the jaw crusher is mainly made of high manganese steel. It has high impact resistance, excellent abrasion resistance under strong impact abrasive wear conditions, and almost no breakage.
The impact crusher mainly crushes soft rock materials. The most common impact hammer material in the secondary crushing application is high chromium iron, and very few impact crushers use martensitic alloy steel.
Crushing equipment with good performance can improve productivity and the quality of the final product. Therefore, choosing the right crusher is very important for investors. If you need help finding the right crusher, or if you want a professional to customize a crusher for you, please contact us.
