There are several sorts of products to cast crusher blow bars. Various working scenarios require different material blow bars. Based on abundant experience, Qiming Machinery aids you to evaluate the different products for crusher blow bars.
This is generally manganese steel. This alloy is used in main crushers or crushers that have vagrant iron in the feed. Manganese steels will certainly be utilized whenever extremely high shock resistance or some elongation is required. The impact bar life is not easily foreseeable and relies on many aspects. Manganese crusher strike bars are generally utilized main crusher applications and also give high shock resistance as well as are offered in both Mn14% and also Mn18% material grades. They are well-matched to applications where vagrant iron is feasible in the feed material. Manganese bars are frequently made use of as a ‘risk-free’ selection, however, other materials readily available can supply significant life price advantages. For recognition functions, manganese steel strike bars are repainted black or red and also significant with the respective worldly grade. Likewise, inquire about our unique high-performance material that is proven to exceed other grades of manganese impact bars.
Martensitic steel will certainly be made use of whenever hardness and influence resistance are both required, i.e. in all the applications where use of white (chromium) irons can cause breakage. Normally, martensitic steel has a higher lifetime than Mn steels in more unpleasant applications when the feed size is listed below 900mm. It is used in primary as well as reusing applications. Martensitic steel strike bars are generally utilized where the application requires the impact resistance manganese gives and also the hardness and put on resistance of chrome irons. Typically used in both quarrying and also reusing, martensitic would generally be anticipated to surpass manganese steel in unpleasant applications.
White irons are used when the shock degree is instead reduced and also the spreadings rather thick. Feed to the crusher need to be well prepared as far as top dimension as well as needs to be devoid of tramp iron. As a result of the breakable nature of this alloy, tramp iron will create devastating failure of the strike bars. This product is used in secondary, tertiary as well as asphalt reuse applications where there is no vagrant iron. Cast white chromium iron is extensively used in ‘timeless’ horizontal effect crushers and is available in medium 20% and also high 26% chromium web content products. White irons can provide high performance in the appropriate application giving NO vagrant iron is present in the feed product. The fragile nature of chrome irons indicates considerable damages can happen if vagrant iron or large large-scale product is fed right into the crusher.
Chromium Steel+ Ceramic.
This is a structure impact bar consisting of tough ceramic particles on the wear surface in a chromium iron matrix. This composite has the effect of integrating the extremely tough surface of ceramic with the valuable mechanical residential properties of chromium iron. These (chromium/ceramic) blow bars can have 2 to 4 times the life of common mono-alloy blow bars. Chrome Iron with ceramic is a costs composite metallic matrix iron with difficult ceramic alloy inserts on the wear surface area. The tough alloy porcelains combined with either tool chrome or high chrome iron matrix gives a considerable functioning life advantage over standard chrome iron bars. Whilst this material can be very successful in secondary applications, it needs to not be used for main squashing or extremely hard and rough applications.
Martensitic Alloy Steel + Ceramic.
Martensitic alloy steel with ceramic is a premium composite metal matrix steel with difficult ceramic alloy inserts on the wear surface. The difficult alloy ceramics combined with either martensitic steel matrix supplies a substantial working life advantage over conventional martensitic steel bars. This material is generally used in recycling markets and primary squashing in quarries. Certain applications are unsuitable for this product, consisting of limestone squashing as well as slag recycling. This blow bar including tough ceramic fragments on the wear surface area in a new martensitic steel matrix. The ceramic inlay is much deeper and also larger than basic Xwin and will supply a greater lifetime. These are high-performance impact bars for recycling applications.
Chromium Steel + Titanium Carbide Bars.
MGS Casting has actually succeeded to develop a new material for crusher strike bars users. Titanium carbide bars put the working face of impact bars to increase the blow bars cover life. Compare with typical chromium steel or martensitic steel, it’s period of life can greater than 3-5 times. Nonetheless, the rate for TIC insert impact bars simply a little pricey than others, so it is one of the most competitive products for crusher strike bars.
