· At 800 °C and 1200 °C, the crushing strength increased from 14.87 ± 8.30 N for the 2.8–4 mm granules to 138.39 ± 25.35 N for the +11.2 mm granules. From room temperature to 400 °C, the crushing strength increased from 35.28 ± 23.89 N for the 2.8–4 mm granules to 536.17 ± 183.35 N for the +11.2 mm granules.
· Sintering of ores emits up to about 5 kg/t of finished sinter, but after appropriate abatement maximum EU values in sinter strand waste gas are only about 750 g of dust per tonne of sinter, and minima are only around 100 g/t, but there are also small quantities of heavy metals, with maxima less than 1 g/t of sinter and minima of less than 1 mg/t (Remus et al., 2013).
· The CR was decreased and the sinter strength was improved. Besides, differences of the CR between the upper and lower bed are 16.5 K/min and 7.5 K/min in each cases, reduction of the differences means that homogeneity of sinter strength could be increased in the sintering bed.

· The hot sinter crusher reduces the lumps of sinter cake to a size smaller than 150 mm, in preparation for cooling and secondary crushing. Since the sinter cake retains a temperature of around 850 deg C at the time of leaving the strand, the hot sinter crusher operates in a very hostile environment. Hence the design of the hot sinter crusher is to take care of this hostile environment.
F. Verdeja (2017) Iron Ore Sintering: Quality Indices, Mineral Processing and Extractive Metallurgy. Review, 38:4, 254-264, DOI: 10.1080/08827508.2017.1323744 . improves cold crushing strength .
The cold strength of sinter is determined by the tumbler index, and depends on the strength of each individual ore component, the strength of the bonding matrix components and the ore composition. This index determines the size reduction due to impact and abrasion of the sinters during their handling, transportation, and in the blast furnace process.
· Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product of a suitable chemical composition, quality (physical) …
· The physical strength or cold strength of the sinter at room temperature as measured by the shatter or tumbler test The value of reduction degradation index (RDI) which is the breakdown of sinter following reduction at low temperatures (550 deg C) determined by the reduction degradation test.
· The sinter TI with 7% NF ore addition could meet the production requirements for its TI was higher than 65%. Totally, the method of V–Ti magnetite ore blend optimization for sinter strength based on iron ore basic sintering characteristics was useful.
· Fig 1 Schematics of sinter mix and product sinter Sintering process is a generic term that is used to describe the process of agglomeration of a green mix of iron ores, fluxes and coke and plant solid wastes having a particle size of -10 mm so as to produce sinter which can withstand operating pressure and temperature conditions existing in a BF.
· The reduction behavior and crushing strength of SI–C were then examined with a quartz-made fixed bed reactor and with a tensile and compression testing machine, respectively. 2. Experimental 2.1. Sample. Agglomerated iron ore sinter (SI) was supplied by the Japanese steel company and used in this work.
cold crushing stregth of iron ore and sinter. 20 Jun 2016 show that the cold crushing strength of the pellet increase with the decrease of porosity In general pellets differ from lump and sintered ores.
Depending upon the characteristics of the ore materials and the sintering conditions, daily average production rate of 22.5–44 tons/sq m/day of grate area is expected from the sinter machines. After the end of the travelling grate, the sinter passes through a spiked roll crusher and the hot screens to the sinter …

· The method of V–Ti iron ore blend optimization for sinter strength based on iron ore basic sintering characteristics is useful. (2) The BSCs of 5 kinds of V–Ti ores DB, HW, YT, JL and FH are good except LF. (3) The key reason that V–Ti sinter with a poor TI is the low LF, which caused the sinter with a large-pore structure.
Fine concentrates are mixed with crushed returned sinter to give a material containing about 6.5 percent sulfur. This is fed onto a moving grate and fired in an updraft of air, and the sintered cake leaving the machine is broken into a convenient lump size. By virtue of its strength and hardness, sinter is an ideal feed for the blast furnace.

manufacture of Manganese Ore Sinter on a continuous sinter plant of 20 Tons per day capacity. Introduction In the process of mining of ores, a lot of fines is generated. Similarly in operations such as crushing, screening. transporting Et stacking, a large quantity of fines is generated For smelting operation in furnace, raw materials in a
Sinter strength also reaches maximum values when sinter FeO values of 8.6-9.88%, because of the presence of more acicular SFCA phase (fine acicular SFCA minimizes the number of cracks and large .
sinter bonding strength, crushing of product sinter, and selection of return nes screen aperture [19,20]. Non-uniform sintering usually results in part of the
· Additionally, the sintering of ore grains also happens, leading to the development of mechanical strength. This sintering may be caused by solid state interaction of particles, but also with the presence of liquid phase, which can act as transport media increasing the sintering rate. The liquid phase also acts as bonds among ore particles.
After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm. This is also known as lump ore. In addition to lump ore, fine ore (approx. 1 mm) and ground ore (ore powder) (approx. <0.1 mm) can also be obtained by crushing and grinding.
