processing girth gear of rotary kiln, what material wear resistance is high? - xinxiang great wall machinery co., ltd - pdf catalogs | technical documentation | brochure

Processing girth gear of rotary kiln, what material wear resistance is high? The girth gear is one of the more commonly used parts in large mechanical equipment (such as rotary kiln, ball mill). Its function is to transmit and change the direction of force through the large ring gear. The large ring gear belongs to the thin-walled ring castings. In the casting process, problems such as uneven thickness, folding, and ellipse are prone to occur. Therefore, it is necessary to pay attention to the details of the casting process to improve the quality of the casting during the processing. Due to manufacturing capabilities, transportation and installation requirements, the girth gear is composed of two half gears that are joined together by counter screws and tangentially fixed to the kiln body by spring plates. To complete the installation and alignment of the girth gear with high quality, it is necessary to develop a scientific and feasible construction plan whether it is newly installed or reset after overhaul. On the casting girth gear, CHAENG uses high-quality ZG45, ZG42CrMO and other cast steel materials, and uses a unique heat treatment technology in the casting, which optimizes the ring gear structure, improves the hardness, and greatly improves the wear resistance and impact resistance of the product. The girth gear is one of the key components in the rotary kiln transmission. The installation quality directly affects the stability of the rotary kiln drive system, the stability of the rotary kiln operation, the service life of the kiln lining and the rotary kiln operation rate.

Therefore, CHAENG uses high-strength steel for girth gear casting during processing, and optimizes the transmission characteristics of the rotary kiln to ensure the stability of the components under long-term operation and prolong the service life of the components.

crusher blow bars material selection

crusher blow bars material selection

There are many kinds of material to cast crusher blow bars. Different working situations need different material blow bars. Based on rich experience, MGS Casting helps you to analysis the different materials for crusher blow bars.

This is mainly manganese steel. This alloy is used in primary crushers or crushers that have tramp iron in the feed. Manganese steels will be used whenever very high shock resistance or some elongation is needed. The blow bar life is not easily predictable and depends on many factors. Manganese crusher blow bars are commonly used primary crusher applications and provide high shock resistance and are available in both Mn14% and Mn18% material grades. They are well suited to applications where tramp iron is possible in the feed material. Manganese bars are often used as a safe choice, however, other materials available can offer significant life costs benefits. For identification purposes,manganese steel blow bars are painted black or red and marked with the respective material grade. Also, ask about our special high-performance material that is proven to outperform other grades of manganese blow bars.

Martensitic steel will be used whenever hardness and impact resistance are both needed, i.e. in all the applications where usage of white (chromium) irons can lead to breakage. Generally, martensitic steel has a higher lifetime than Mn steels in more abrasive applications when the feed size is below 900mm. It is used in primary and recycling applications. Martensitic steel blow bars are commonly used where the application requires the impact resistance manganese provides and the hardness and wear resistance of chrome irons. Commonly used in both quarrying and recycling, martensitic would normally be expected to outperform manganese steel in abrasive applications.

White irons are used when the shock level is rather low and the castings rather thick. Feed to the crusher must be well prepared as far as top size and must be free of tramp iron. Because of the brittle nature of this alloy, tramp iron will cause catastrophic failure of the blow bars. This material is used in secondary, tertiary and asphalt recycle applications where there is no tramp iron. Cast white chromium iron is widely used in classic horizontal impact crushers and is available in medium 20% and high 26% chromium content materials. White irons can provide high performance in the right application providing NO tramp iron is present in the feed material. The brittle nature of chrome irons means significant damage can occur if tramp iron or large oversize material is fed into the crusher.

This is a composition blow bar consisting of hard ceramic particles on the wear surface in a chromium iron matrix. This composite has the effect of combining the very hard surface of ceramic with the useful mechanical properties of chromium iron. These (chromium/ceramic) blow bars can have two to four times the life of standard mono-alloy blow bars. Chrome Iron with ceramic is a premium composite metallic matrix iron with hard ceramic alloy inserts on the wear surface. The hard alloy ceramics combined with either medium chrome or high chrome iron matrix provides a significant working life advantage over standard chrome iron bars. Whilst this material can be very successful in secondary applications, it should not be used for primary crushing or very hard and abrasive applications.

Martensitic alloy steel with ceramic is a premium composite metallic matrix steel with hard ceramic alloy inserts on the wear surface. The hard alloy ceramics combined with either martensitic steel matrix provides a significant working life advantage over standard martensitic steel bars. This material is commonly used in recycling industries and primary crushing in quarries. Certain applications are unsuitable for this material, including limestone crushing and slag recycling. Thisblow bar consisting of hard ceramic particles on the wear surface in a new martensitic steel matrix. Ceramic inlay is deeper and wider than standard Xwin and will provide higher lifetime. These are high-performance blow bars for recycling applications.

MGS Casting has succeeded to develop a new material for crusher blow bars users. Titanium carbide bars insert the working face of blow bars to expand the blow bars span life. Compare with normal chromium steel or martensitic steel, its span life can more than 3-5 times. However, the price for TIC insert blow bars just a little expensive than others, so it is the most competitive material for crusher blow bars.

It is an important thing when to change crusher liner, so as to avoid damage to the liner seating surfaces of the crusher bowl, concave and mantle must be replaced before they are worn through. In someconditions with good quality wear parts , approximately 50% of the liner weight is consumed when liners are worn out. It is important to keep a record of liner wear in order to assess the degree of liner wear, if not,maybe, sometimes you need to stop the crusher operation which will decrease your profit.

Typically, distorted wear profiles can cause a reduction in capacity. Other symptoms of poorly worn liners are high power draw and ring bounce. Also, the wear life can bereduced because the wear is sometimes concentrated in a small zone rather than spread along the full cavity and the cavity may have to be replaced before they are fully worn. This results in poor utilization and a higher operating wear costs.
