Cold crushing strength. Unlike sinter, pellets are close to spherical in shape. Therefore, the mechanical property of pellets can readily be measured by a compression test. ISO 4700:2007 was developed to determine the CCS of iron ore pellets. In accordance with ISO 4700, the cold crushing strength (CCS) of pellets is the arithmetic mean of
The strength of reductant mixed re-duced pellet was observed to be affected by the nature of reductant. The reductant with low bulk density and lower carbon content provided higher voidage rendering lower strength. The cold crushing strength (CCS) of reduced pellets observed in this study ranged from 5 to 200kg exhibiting ductile to brittle behav-
Cold Crushing Strength Of Pellet. Cold crushing strength of iron ore pellets pct 09b automatic system for determination of the cold crushing strength ccs of fired iron ore pellets and reduced iron ore pellets iso 4700, astm e 382 chat with sal 552 crushing strength test system orbit technologi crushing strength test system is a fully.
The cold crushing strength of the pellet improved from 203 to 220 kg p −1 with increase in fineness. With increase in percentage of −325# particle size in the ground product RDI of the pellet decreased from 13·8 to 11·9% with increased melt formation from 5 to 9%.
Determination of Cold Crushing Strength (CCS) of iron Ore pellet fired at different temperature. This machine is mainly used in crushing strength test for iron ore pellet, with functions of automatically statistical analysis of iron ore pellets test result as average crushing strength, CV% standard deviation (SD) and calculate CCS force..
The iron pellets are produced with cold crushing strength (CCS) of 210+ and porosity of 22+ which helps to maintain grade in DRI fem 80+ and our product mean particle size (MPS) is ~9.5-10 which assists in reducing oxygen in kiln and maintain consistency in grade. Iron Pellets are used as raw material for sponge iron and blast furnace.

Aug 10, 2015· In the test, a single pellet in a size range of 10.0–12.5 mm is compressed at a specific speed. One test portion comprises at least 60 pellets selected randomly from the test sample. The compression is repeated for all pellets in the test portion. The Cold Crushing Strength is calculated as the arithmetic mean of all the measurements obtained.
pellets. In their study, the Tumble Index (TI) and the Cold Crushing Strength (CCS) increased with the increase in pellet basicity, while the Reduction Degradation Index (RDI) initially decreased, and then increased again with the increase in pellet basicity. The optimal value for blast furnace performance was a basicity of 0.33. In the study by
in the pellets at 1300°C temperature for one hour hardening period, shown higher crushing strength(586.76Kg/pellet) and lower apparent density (2.69 gm/cc) with respect to lump ore(400 Kg/cm. 2. 2and 3.1gm/cc). The formation of more calci-um silicate in basic pellets was imparted higher strength to the pellets in comparison to acid pellet.
Determination of cold crushing strength ccs of iron ore pellet fired at different temperature. this machine is mainly used in crushing strength test for iron ore pellet, with functions of automatically statistical analysis of iron ore pellets test result as average crushing strength, cv standard deviation sd and calculate ccs force..
Shaped bodies containing particulate iron materials, such as cast pellets, briquettes and the like, with sufficient strength to withstand temperatures of up to at least 1000° C. can be obtained by using a fully hydrated high-alumina cement as the binder. The strength of the pellets at elevated temperatures can be further enhanced by adding small amounts of bentonite, silica fume or other
The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion. Refractories with high CCS are also expected to have higher
