One of the biggest operating costs for a gyratory crusher unit is the need to change the liners. The mantle liner is made from one type of material. Single liners have several disadvantages, including the fact that they are large and expensive to replace per ton of ore crushed. The process of changing liners requires the removal of the mainshaft, which is time consuming and dangerous.

Often, crusher liners are worn out completely. While a partial replacement may not be necessary for most operations, a premature replacement could result in an uneconomical situation for the company. Choosing the right time to change liners is critical to achieving maximum liner utilization. If you choose to replace the lining too early, you risk damaging the head of the machine and wasting production time.

A full operation will improve the life of the new liners. The first step in replacing gyratory crusher liners is to determine the density of the material to be crushed. Once this is determined, the liners should be replaced. The full operation of the machine should be carried out for at least six hours or seventy percent of the capacity of the machine. After the full operation, you should check the lining condition and make the necessary replacements.

The next step is to select the proper type of gyratory crusher liners. The choice of the right liners is dependent on the application and operating parameters. A properly selected version will depend on the abrasiveness/wear properties of the crushing medium. As a general rule, austenitic high manganese steel is recommended for most applications. An open side setting is the largest gap between the mantle and the concave.

The first step to change gyratory crusher linings is to monitor the amount of stone that goes through the machine. The lining should be changed when it reaches the desired level of wear and tear. If it is still in good condition, you may be able to run it for a longer time. If the stone goes through the gyratory crusher liners at the end of their operational life, the cone will be unable to function effectively. If you fail to do so, it will be damaged and reduce production.

Another important aspect of gyratory crushers is the lining assembly. The two halves of the crusher have different shapes. The outermost segment of the gyratory mantle liner is usually thicker, so it can hold more material. The retaining ring is positioned between the upper and lower halves of the mainshaft. The upper and lower liner sections are generally made of heat-treated alloy material.

When to change gyratory crusher linings? While liners are essential for maximizing performance and reducing maintenance costs, they will eventually wear out. In some cases, the liners will need to be replaced more frequently than once. This will cause the crusher to become less efficient and produce lower-quality product. However, the process of replacing liners is not without danger.

The gyratory crusher has two parts: the mantle and the bowl liner. The mantle liner assembly is the largest and has the largest capacity. The bowl liner is smaller and is used for further size reduction. The cone crusher is smaller than a gyratory crusher. It has the advantage of low energy consumption and minimal maintenance. Its only disadvantage is that it does not allow for a large particle size.

The most important part of a gyratory crusher is its lining. The lining is the part of the crusher that breaks down ore. Consequently, it is essential to maintain the condition of the liners to ensure optimal performance. If the liners aren’t changed, the lining will need to be replaced. It can cause severe problems to the machine if not changed on time.
