Gyratory Crusher Liners

Gyratory crusher liners are components of the gyratory crusher, which is a primary crushing machine used in the mining industry. The liners are used to protect the gyratory crusher’s mainframe and other components from wear and damage caused by the materials being crushed.

The gyratory crusher liners are typically made of high manganese steel, which is a wear-resistant material that can withstand the high impact and abrasion of the crushing process. They are designed to be easily replaceable, as they can wear out over time due to the constant friction and impact of the materials being crushed.

The main function of the gyratory crusher liners is to protect the mainframe and other components of the crusher from wear and damage. This helps to prolong the life of the machine and reduce the need for costly repairs and maintenance. Additionally, the liners can also improve the efficiency of the crushing process by reducing the amount of material that is lost due to wear and increasing the overall throughput of the machine.


Gyratory Crusher Liners By Qiming Casting®

Qiming Casting is a professional manufacturer of high manganese steel, alloy steel, and high chrome steel in China. We supply various types and brands of high-quality high manganese steel gyratory crusher liners to mines, quarries, and cement plants all over the world. At the same time, in order to help customers solve the problem that ordinary high manganese steel is not wear-resistant, Qiming’s engineers have developed TIC inserts mantle, which has more than double the service life of ordinary high manganese steel liners, more effective in crushing some hard stones.

Manganese Gyratory Mantle

Manganese Gyratory Mantle

Manganese steel is used to cast gyratory mantle for several reasons. First and foremost, manganese steel is a very tough and wear-resistant material that can withstand the high-impact and abrasive nature of the crushing process. This makes it an ideal material for use in the construction of components such as the gyratory mantle.

In addition to its wear resistance, manganese steel has a high tensile strength, which means that it can withstand heavy loads and stresses without breaking or deforming. This is important for components such as the gyratory mantle, which is subjected to high stresses during operation.

the use of manganese steel to cast gyratory mantle is essential to ensure the long-term reliability and durability of the gyratory crusher. By providing excellent wear resistance, high tensile strength, work-hardening ability, and machinability, manganese steel helps to ensure that the gyratory mantle can withstand the rigors of the crushing process and provide consistent performance over time.

Titanium Carbide Inlay Gyratory Crusher Liner

Titanium Carbide Inlay Gyratory Crusher Liners

The titanium carbide rod inserts are made of a proprietary hard alloy designed to augment gyratory crusher liners. We tailor these hard inlays to match the customer’s needs according to site conditions, the results of profile scans performed by Qiming Casting specialists, and material samples. Through these methods, and collaboration with the on-site crushing and maintenance personnel, we determine where to apply the titanium carbide rod inlays based on the liner’s maximum wear zone.

The titanium carbide rod inlays increase the hardness and durability of the surrounding manganese steel and are especially useful in both extreme applications and when there is not enough natural compression in the crushing zones for traditional manganese to work harden efficiently.

Frequently Asked Questions

How to install gyratory crusher liners?

Installing a gyratory crusher mantle requires careful planning and execution to ensure safety and efficiency. Here are the general steps to follow:

  1. Shut down the crusher and lock out the power source to prevent accidental start-up.
  2. Remove the old mantle by cutting it off with a torch or breaking it with a hammer. Be sure to wear appropriate personal protective equipment (PPE) and follow safety protocols.
  3. Clean the surface of the head and the mantle seat to remove any debris, dirt, or rust. Inspect the mating surfaces for wear, damage, or cracks.
  4. Place the new mantle on the head, making sure it is centered and level. Use a crane or other lifting device to lift the mantle into position if necessary.
  5. Install the mantle by tightening the nuts or bolts evenly and gradually in a cross pattern, starting from the center and working outwards. Use a torque wrench to ensure that the bolts are tightened to the manufacturer’s specifications.
  6. Verify that the mantle is seated properly and securely. Check for any gaps or misalignment between the mantle and the head.
  7. Reconnect the power source and start up the crusher. Conduct a visual inspection and run a test to ensure that the crusher is operating correctly.
  8. Document the installation process and any maintenance performed for future reference.

It’s important to note that the above steps are general guidelines, and the specific process may vary depending on the manufacturer’s instructions and the type of crusher being used. Always consult the manufacturer’s manual and follow established safety procedures when working with heavy machinery.

What is the material for gyratory crusher liners?

The material used for gyratory crusher liners depends on several factors such as the type of rock being crushed, the operating conditions of the crusher, and the manufacturer’s specifications.

For the gyratory crusher mantle,  Qiming Casting gives two choices: Standard manganese steel and TIC inserts manganese steel.

Manganese steel is a high-strength alloy steel that contains around 12-14% manganese. It is a tough and wear-resistant material that can withstand high impact and abrasion. Manganese steel is also able to work hard, meaning that it becomes even harder and more wear-resistant as it is subjected to impact and pressure over time.

TIC inserts manganese steel gyratory crusher mantle, which is developed by Qiming Casting for crushing hard stones.

For gyratory crusher concave segments, different areas need different liners. The gyratory crusher concave segments are divided into three areas: upper intake liners, chamber middle liners, and chamber bottom liners.

Upper Intake Liners

  • Manganese alloys
  • Low-alloy steel, impact resistant

Chamber Mid Liners

  • High manganese alloys
  • Low-alloy steel, abrasion, and impact resistant

Chamber Bottom Liners

  • Low-alloy- steel, high abrasion, and impact resistant
  • High-chrome special, maximum abrasion resistance

What is the largest gyratory crusher liners you can produce?

The largest gyratory crusher liner our factory can produce is 12 tonnes.
