durability of animal feed pellets, as well as to investigate the potential for modeling the effects of formulation and processing factors on both pellet durability index (PDI) and pelleting energy consumption, measured in kilowatt hours per ton (kWh/ton). Seven different factors, including
The slag formed a strong bond inside Fig. 5 Effect of basicity on shatter, tumbler and abrasion index of the pellets [28, 29].This bond offered high resistance to pellets abrasion and tumbling, most likely due to their hard fine- grained structure, resulting in increasing crushing strength, shatter and tumbling index.
The process was named as composite agglomeration process (CAP). They reported good results for magnetite pellets in terms of shatter index, tumbler index, reducibility index and reduction degradation index. However, they did not report about the strength of the pellets present in CAP sinter separately or their process details.
Iron Ore pellets are Iron Ore fines that have been concentrated and bonded together to form small balls, or pellets. What is the density of iron ore? ... What is tumbler index of Iron ore?
The Tumbler Index is a relative measure of the resistance of the material to breakage or degradation by impact. (ii) Abrasion Index: It is a relative measure the degradation of iron ore by abrasion. The Tumbler Index and Aibrasion Index are determined in a tumbler test apparatus as per the Bureau of Indian Standard No. 6495

Aug 31, 2013 . iron pellet will soon be in demand by its prospective buyers who are . The Blast Furnace operators are still using 30-40% of Iron ore lumps. They will gradually switchover to Pellets because of high CCS, higher tumbler index,.
Chapter 20: Measuring the Physical Quality of Pellets Figure 20-2. Correlation between a Tube Tester and the standard KSU Tumbler. This tube method has never been standardized by the industry, but it is an effective method and correlates well to the KSU Tumbler. For example, direct comparison between the standard KSU
Seedburos four compartment Pellet Durability Tester utilizes a test developed by Kansas State University to predict the amount of fines produced by handling pellets before feeding time. This is accomplished using a specially designed pellet tumbler which duplicates the amount of breakage that normally occurs from the time the pellets are expelled until they are consumed by the animal.
Dec 28, 2013· BF grade, DRI grade, flux, pellets, swelling, Iron ore pellets. Iron ore pellet is a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of direct reduced iron (DRI) and in blast furnaces for the production of hot metal.
