Reduction Degradation Index- When the iron ore converts from haematite to magnatite its structure changes from hexagonal to cubic in 950 degree centigrade and in such a case some fines are generated. The generation of fines in percentage is called Reduction Degradation Index. It should be 5% approx. Lower the RDI selection of Ore will better. In DRI process lower RDI is suitable. Higher the RDI accretion or agglomeration formation will more.
What else can I help you with?
What is network degradation?
A noticeable reduction of a networks connectivity and response speed
What is the total process of land surface reduction called?
The total process of land surface reduction is called land degradation. It refers to the decline in the quality of land, including its productivity, due to various factors such as deforestation, soil erosion, and pollution. Land degradation can have negative impacts on ecosystems, agriculture, and human livelihoods.
5 activities involve transformation of substance?
Examples: - oxydation - reduction - thermal degradation - polymerization - dehydration
What are 2 basis types of chemical reactions?
Examples: oxidation, reduction, synthesis, thermal degradation, polymerization, etc.
What is tumble index?
Defined as 'a relative measure for evaluating the resistance of iron ores to size degradation by impact and abrasion' (ISO 3271:1995), also known as abrasion index. Index used in certificate of analysis of iron ore pellets.
What is tumbler index of limestone?
The tumbler index of limestone represents its susceptibility to degradation during transportation and handling processes. It is typically measured as the percentage of material that remains within a specified size range after tumbling in a drum. A lower tumbler index indicates a higher resistance to breakage.
What is a mission degradation?
Mission degradation refers to the reduction in the effectiveness or performance of a system or operation, often due to unforeseen circumstances or failures. This can occur in various contexts, such as military operations, space missions, or technological systems, where essential functions are compromised. Factors contributing to mission degradation may include equipment malfunctions, environmental conditions, or operational errors. Addressing mission degradation typically involves implementing contingency plans or corrective measures to restore functionality and achieve objectives.
What does Rw dB mean in acoustics?
The ability of a material to absorb sound is assessed in the laboratory by taking measurements over a recognized range of frequencies. The average of these measurements is expressed as Rm or the Mean Sound Reduction Index. When adjusted for the ear's response to loudness it is termed Rwor Weighted Reduction Index and is expressed in dB or deciBels. DeciBel is a unit of measurement of the loudness or strength of a signal.
What is catabolism and what is anabolism?
Catabolism is breaking down process or degradation phase. It happens when you are sick or fasting (not eating). Anabolism is biosynthesis process or reduction phase like making protein from amino acids.
What does chemical and physical processes include?
Physical processes: melting, boiling, grinding, sieving, vaporization, deposition, etc. Chemical processes: polymerization, oxidation, reduction, chemical reactions, thermal degradation, dissociation, etc.
How degradation study will carryout?

What is agenda 21 name five items Agenda 21 must deal with?
Agenda 21 must deal with issues related to sustainable development, poverty reduction, environmental degradation, population growth, and resource management.
