When should you replace your cone crusher liners? Manganese steel, or even the more expensive cast iron ones? Here are a few tips to keep in mind. The material should be able to withstand the rigors of a cone crusher’s feed materials. The thickness of the liners should also be considered, since larger liners will tend to crack quicker. When changing the liners, be sure to check the thickness at the bottom of the cone and the head of the cone.
Manganese Steel
The most common and critical wear part of a cone crusher is the cone liner, which directs the materials through the crusher. Cone liners must be replaced on a regular basis to prevent the risk of excessive wear. Manganese steel cone crusher liners, manufactured by H-E Parts, have a proven track record of long-term performance, and their design makes them compatible with lifting devices for a safe and efficient service function. The company’s flagship MnElite(tm) grade of manganese wear products typically achieve an improvement in life of up to 35% over lower grades of materials. While these improvements are often attributed to increased durability, they go beyond extended liner life.
Hardness tests
In order to improve the design of crusher liners, hardness tests have been used in the mining and aggregate industries. This research involved a computer model that can predict the geometry of a worn cone crusher based on the hardness values of the liners. The model showed some variance from the measured geometry. In addition, manganese steel is widely used for rock crusher liners, due to its work hardening properties. Its higher hardness would explain its lower wear rate.
Interparticle breakage
A cone crusher’s linings should be replaced when they’re at least one inch thick at the bottom and have begun to crack and disintegrate. When the liners are less than a half inch thick, a 10-percent decrease in production is an indication that it’s time to change them. Depending on your machine, you may even receive a reminder to change the liners automatically. It’s worth considering regular maintenance of your equipment, so that you can get the most out of your investment.
Cost of liners
Cone crusher liners reduce the volume of the crushing cavity and feed opening of the cone crusher. If the liners wear out, a 10% loss in production is enough to justify changing them. If not, failure to replace the liners will not only cause a loss in production, but can also damage internal crusher components. Therefore, it is essential to regularly replace the cone crusher liners to maintain the productivity of the cone crusher.
Chamber Selection
It is important to select the right chamber configuration for your cone crusher, as an inadequacy in this area can lead to increased downtime, low efficiency, and even mechanical damage to the crusher. Fortunately, there are several factors you can consider when choosing the right liner for your cone crusher, including maximum feed size, desired gradation, and wear life. In this article, we will discuss the benefits of each, and what you should look for when selecting a liner.
