impact crusher vs. jaw crusher, which one should i choose

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.

Not every crusher is suitable for every application. When choosing the best crusher for aggregate applications, it is important to understand how the crusher works and its impact on efficiency, operating costs and final products. When designing aggregate processing production line plans, there are usually differences in the choice of impact and cone crusher. What is the difference between impact crusher and cone crusher? Which is the best fine crushing equipment?

For impact crusher, the high-speed rotating rotor throw stone into impact plates, stones are crushed via impact energy produced rotating rotor. So, impact crusher is good to crush soft material of brittle stone.

Initial High-manganese steel is softer than high-chrome steel, but high-manganese steel has features of high tenacity, that means after many times strike and crushing stone, this high-manganese steel will become harder and harder, so, high-manganese steel is usually used to crush hard stone, and its service life will be very long. So, both jaw plates of jaw crusher and bowl liner & mantle of cone crusher are made from high-manganese steel.

High chromium iron is very hard, but it is a little brittle, so, it usually used to crush soft material like lime stone. Therefore, the most common blow bar/hammer material of impact crusher is high chromium iron.

According to our experience in Zambia and Nigeria, most of the local raw materials are hard stones like granite, so most investors or equipment owners in Zambia and Nigeria usually use cone crushers as secondary crushers. Because of its high production efficiency and low maintenance costs for hard stones.

Due to the different types, sizes and uses of stone crushers, and the large investment required to purchase stone crushers, it will make the purchase of equipment difficult. When you are looking for crushers or other aggregate equipment, please contact our aggregate equipment experts to help you make the right choice in the first time.
