Advantages of Zhixin cone crusher liner
1. The use of more than 40 kinds of rare metals and high manganese steel to combine in a progressive and perfect way makes the wear resistance of our cone crusher liner significantly higher than that of conventional wear-resistant parts, and the service life is 2-3 times that of conventional products.
2. The Ministry of Science and Technology of China authoritatively certified that the tensile strength of our crusher wear-resistant parts is greater than 1500MPa, the hardness is greater than HRC68 degrees, and the impact toughness is greater than 119J/square centimeter. Our cone liner has both strength and toughness, and the key is super wear resistance.
3. We dare to promise that if it does not reach twice the service life of your previous conventional wear-resistant parts, we will refund the full amount. We can write the clause in the invoice!
The main functions of the cone liner include
The gaps between the concave and mantle prevent the crusher cylinder from directly bearing the impact and wear of the material, which plays a buffering role and reduces the loss of the equipment body.
By adjusting the working state of the grinding body, the material crushing path is optimized, the crushing efficiency is improved, and the loss of the medium and liner is reduced.
Control the particle size of the discharge material to avoid over-crushing or under-crushing, and ensure the stable quality of the finished product.
Reasonable selection of material and shape design (such as high manganese steel, alloy steel, etc.) can significantly improve wear resistance and reduce replacement frequency of cone crusher liners.
Material characteristics
The most widely used. Generally the basic material of our cone crusher liners is Mn18Cr2, this material has good toughness. When it is impacted and rubbed by ores, the surface will produce work hardening, and the hardness can be improved to a certain extent, so it has good wear-resistance.
Crushing lining made of materials such as high chromium cast iron are also gradually emerging. High chromium cast iron has high hardness and excellent wear resistance. It is suitable for crushing operations of some high-hardness ores and can effectively extend the service life of the crushing lining.
The higher the hardness of the ore and the stronger the abrasiveness, the faster the wear rate of the crushing lining. For example, the wear of the crushing lining when crushing granite will be much faster than when crushing limestone.
If the feeding speed of the ores is too fast and the feeding particle size is uneven, the load on the crushing liner will be unstable, resulting in increased local wear and shortening of the service life.
Regular maintenance of the crusher, including timely cleaning of the crushing chamber and lubrication of related parts, can reduce abnormal wear of the crushing liner and extend its service life.
Installation and replacement
During installation, ensure that the cone crusher concave fits tightly with the cone crusher mantle. Generally, special bolts and other connectors are used for tightening, and the installation accuracy must be ensured to avoid installation deviation and other situations that affect the normal operation of the crusher.
When the crusher liner is worn to a certain extent, affecting the crushing effect (such as the product particle size does not meet the requirements) or when it is damaged, it needs to be replaced in time. The replacement process must be carried out strictly in accordance with the equipment's operating manual to ensure that the new crusher liner is installed correctly.
Frequently Asked Questions (FAQ)
The mantle (moving cone) does a pendulum motion driven by an eccentric sleeve. When ore enters the crushing chamber, the changing distance between the concave (fixed cone) and the mantle crushes the ore through extrusion, bending, and impact.
Zhixin liners combine high manganese steel with over 40 rare metals, offering a service life 2-3 times longer than conventional products. They feature certified tensile strength over 1500MPa, hardness above HRC68, and high impact toughness.
We primarily use Mn18Cr2 high manganese steel, which hardens under impact. We also utilize new composite materials like high chromium cast iron for crushing extremely hard ores to extend operating life.
Ore hardness and abrasiveness directly impact wear speed. For example, crushing highly abrasive granite wears down the lining significantly faster than crushing softer limestone.
Liners should be replaced when wear affects the crushing performance (e.g., when discharge particle size no longer meets requirements) or when physical damage is observed, following the equipment manual strictly.
