Which factors affect crusher wear parts span life?

In recent years, advances in the metallurgy of crusher wear components have assisted operators in minimizing the effect of wear on their operations.

Managing wear is a never-ending struggle, whether it’s loading run-of-mine ore or handling concentrates for storage or transportation. Because mines that operate soft, non-abrasive ores are few and few between, keeping wear under control is a key expense item in the production budget for the overwhelming majority of operations. A failure to do so may have significant economic ramifications; as a result, high-wear components should be coated with materials that are both durable and resistant to continuous abrasion, as well as those that safeguard equipment and materials-handling equipment built of standard steels.

Some clients (crushers, plant users, and new traders, for example) often ask us the following questions: How long is the product’s shelf life? Which kind of material is the most appropriate? Is the Mn18 a better option than the Mn13? The difference between Mn13 and Mn18 is as follows:

As a casting worker, I’d want to share my knowledge of the variables that influence the usable life of crusher parts. We will just be talking about the casting wear components for the crusher in this section (manganese casting parts and chrome casting parts, such as cone crusher wear parts, VSI crusher wear parts, Gyratory crusher wear parts)

Material Selection for Crusher Parts

The majority of crusher components, with the exception of the blow bar, are made of manganese steel (The blow bars material is high manganese). In manganese steel, there are three trademarks. Magnesium 14, Mn18, and Mn22 When high manganese steel is subjected to severe impact or crush stress, the surface of the steel hardens extremely rapidly, but the steel’s body retains its excellent toughness. As a result, the more appropriate the surface hardens, the better the wear. A low hardness (HB170-230) is characteristic of high manganese steel, and unless the uncured wear is very restricted and the surface is adequately hardened, the wearable cannot be guaranteed.

Accordingly, which material is the best option depending on the goods that have been crushed. For manganese casting foundries, the abandoned manganese steel may have enough “Mn” elements to meet the required content. However, if you need a manganese concentration of 18 percent or more, electrolytic manganese is the sole option.

Treatment with High Temperatures

  • The most critical stage in the casting process since it has the most impact on product quality.
  • To prepare for heat treatment, the casting surface must be cleaned.
  • The time between the casting furnace and the water pool must be strictly controlled.
  • The amount of carbon on the surface of the product must be reduced.
  • And the water pool temperature (according to European standards, the water pool temperature must be less than 20 degrees Celsius) must be carefully monitored.

Machining and Printing.

Upon completion of heat treatment, the castings will be sent to a machining workshop for further machining to adjust the casting size and make it suitable for use in a crusher plant. At the end of the process, printing makes them more visually appealing and serves to preserve them against oxidation.
