Our premium manganese crusher liners for cone, jaw, gyratory, and impact crushers are cast using varying grades of manganese steel.
GRADES OF MANGANESE
When selecting manganese crusher liners, the liner percentage indicates the amount of manganese used in the casting. Our quality cast liners come in 14%, 18%, and 22% manganese. Manganese is used in wear parts as it is a material that hardens as it wears, improving its life as it work hardens. Not all applications will allow a set of liners to achieve the level of hardness in the life of their liners so it’s not always advisable to just select the highest percentage. Our customers rely on our crusher specialists to suggest the right parts for their equipment to help optimise crusher performance, output, or material shape size.
When selecting the correct grade and profile, our team will get to know your equipment, environment, current liner life, and the abrasiveness of the materials before making a recommendation.
Our standard grade manganese contains between 12% and 14% manganese steel. Although the standard grade contains less manganese than others, it’s offset with an adequate amount of carbon and chrome to help the liners reach a work-hardened state once in operation sooner, realising an improvement in performance for our customers’ equipment. Typically, our 14% is used in liners that have low wear rates or aren’t crushing continuously.
Our high-performance grade work hardens in place faster due to the increase in manganese and subsequent variation in carbon & chrome content. As the majority of wear is achieved shortly after installation, it’s desirable for customers to get the liner to the work-hardened state sooner to achieve the benefits of the liner and to maintain the liners new profile. When the wear drops off and liners achieve their work-hardened state, our liners offer consistent wear across the profile and extend life-supporting customers with cost-effective solutions and reduce unexpected maintenance or shuts.
Our ultimate performance grade manganese offers customers a superior performing liner for highly abrasive applications. With an increase in abrasive material, more wear accumulates faster. If the material isn’t suited to withstand the initial wear and achieve a work-hardened state, the liners won’t achieve the life desired to meet maintenance schedules or appropriately crush and shape the product.
With a higher carbon content and manganese and a lower chrome content, our ultimate performance liners retain the profile after installation by achieving a work-hardened state faster than other grades, allowing the profile to remain and crusher performance and increase liner life.
Our liners are cast to set tolerances and are precisely machined to provide a superior finish that offers customers durable and reliable crusher parts to optimise and extend the life of their equipment.
Our strong and mature relationships with our foundries have resulted in a superior understanding and focus on the casting process and quality of our wear parts. All our manganese castings are put through a heat-treatment process that retains the toughness of the manganese material that results in the hard-wearing liners that are suited to our industries crushing needs. The result of this heat treatment process is that our parts are less likely to have failures as all care has been taken to ensure a reliable and consistent product is cast for our customers.
To further improve performance and extend the life of our castings we often add special metals such as Molybdenum to make the casting tougher in situations of hard and abrasive rock! We also do special machining to the working face of liners as this will extend the life of a casting as the machining work hardens the surface, slowing down the normally initial rapid wear.
To add to our casting quality and processes, we also have internal quality control processes when the parts arrive in our locations, and we provide full warranties across all of our liners.
