The Smart Guide to Manganese and High Chrome Castings
Practically every crushing operation these days is looking for ways to cut costs and increase production. One way you can find a lot of potential savings is by carefully choosing the right manganese castings. Look closely at your entire crushing operation from start to finish: the material you're crushing, the type of crusher you're using. Give extra attention to the profile of the crushing parts. By matching the profile of the manganese part to your operation's requirements, you can run more efficiently with less downtime and lower operating and maintenance costs.
What to look out for when buying manganese castings
Here some factors to consider when buying manganese castings. Asking the right questions before buying can save you money now and lower-costs of future operations.
Manganese content is critical to the wear life of your crusher parts and the cost efficiency of your operation.
Manganese content can range between 9% - 24% and is usually referenced as;
- 14% = 13-14% MN
- 18% = 17% - 19% MN
- 21% = 21% - 24% MN
Castings with any of these manganese percentages could be the right ones for your application. It just depends on what you're crushing. While you could use a higher percentage of manganese for cones or jaws, 14% manganese can work fine for hard non-abrasive materials. Remember manganese must "work-harden" for optimum performance, which should be matched with material hardness. The hardness & abrasiveness of the rock to be crushed should determine the manganese content for your operation.
Jaw crusher wear parts
Critical factors for jaw crusher wear parts are how long they last and how efficiently they crush the material. Jaw weight, tooth profile and proper fit are all important considerations for efficient crushing. Efficiency requires proper tooth design. Tooth profile can be determined for each crushing application with the help of our experienced service representatives.
Cone crusher wear parts
The critical factors for cone crusher parts are the open and closed side feed settings. The reduction ratio is the top size of the feed opening divided by the closed side setting (CSS) in inches. Reduction ratio will help determine the proper profile for each operation — most options are coarse, medium, and fine profiles. Be sure to match the profile to your crushing needs. Also check the product wear of mantle and bowl liners to confirm wear patterns. OEM specs assure proper fit which minimizes vibration for optimal wear . Knowledge of OEM parts and numbering systems is crucial for ordering the right part.
Horizontal shaft impactor (HSI) crushers are both characterized by low capital costs and properly scheduled maintenance. It's important to minimize these costs and maximize plant uptime by selecting the correct alloy for wear parts. Impact crushers are application-sensitive so you need to consider feed size, type of material and the desired product. HSI crushers, for example, are commonly used by quarry operations, sand and gravel producers and recyclers (where there might be metal in the material.) Selecting the wrong alloy can cause breakage of bars, accelerated wear and catastrophic failure to the crusher.
