In this process the environmental emissions caused by coke and sinter production, and energy lost between pellet induration (heat hardening) and transportation to the blast furnace can be eliminated.

These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets. Raw material preparation – During the process for …...The crushing strength of green micro-pellets was measured by green crushing strength (GCS) equipment of capacity 50 kg (500 N) with least count of 10 g (0.01 N) . During measurement of GCS, the pressure drop of 10% after reaching the maximum load was taken as breakage point. The impact strength of the green pellet was measured by drop number.

A full-scale plant trial of the substitution of a specific organic binder for bentonite was conducted in the company's straight grate pellet plant in Quebec, which produces 9.3 Mtpa of pellets, 36% of which are used as feedstock for the DR process. The results of the full-scale pellet plant trial are given in Table 15.13...The pelleting process starts with a bin (Figure 1, Item 1) in which the mixture of mash is stored. From there, the mash will flow by gravity into the pellet mill (Figure 1, Item 2). This machine is usually located on the ground or main work floor level. The hot, extruded mash (pellets) flows by gravity into a cooler (Figure

characteristics of pellets, especially to avoid the formation of undesirable agglomerates before the pellet formation. Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable ...Pelletizing process changes very fine iron ore into balls with a certain diameter, which is known as pellet . Due to the following benefit are suitable for Direct Reduction plant and Blast Furnace as well: Uniform size range within a range of 9-16 mm. High porosity which gives fast reaction speed, therefore more metallization degree.

Green ball Comments Straight-Grate Grate-Kiln-Cooler No. Items Pellet quality 1 Grate-Kiln-Cooler process enables all pellets to be uniformly and adequately heat-hardened by tumbling action and be held at the peak temperature for longer period than in Straight-Grate. a) Uniformity b) Cold compression strength c) Tumble index...Understanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. …

process parameters and green pellet chemistry during the sample collecting shift were given in Tab le 1. The compos-ite pellet sample was screened to get three different frac-tions: 8–10mm, 10–12.5mm and 12.5–16mm. Cracked and unfired pellets were removed from the sample lot to avoid erratic results. Representative samples from all these...The preparation of iron ore pellets begins with the crushing and grinding of iron ore into a fine powder, and adding reducing additive coke (C) and binding agents and mixing. The mixture is added to a pelletizing machine or ball mill along with a pre determined amount of moisture to form green pellets. These green pellets are air dried and ...

During pellet making, the induration process influences the pellet properties. However, in an optimised pellet production plant, a good pellet induration is expected. . Figure 5 shows the effect of varying pellet basicity on the properties of pellets. It was observed that with the increase in the basicity particularly from 0.10 to 0.50, the CCS ...KIOCL is having facilities to operate 3.5 MTPA Iron-oxide Pellet Plant, Blast Furnace Unit to manufacture 2.16 lakh tonnes per annum Pig iron at Mangaluru, Karnataka.

Based on a prescribed mixing ratio, amounts of different grades of dust are removed from their respective hoppers and added to the ball mill, where they are mixed and made into pellets by the disk-type pellet-izer. These green pellets are dried before they are put into the RHF.

plants and new plants use the grate/kiln. Currently, natural gas is the most common fuel used for pellet induration, but heavy oil is used at a few plants, and coal and coke may also be used. In the vertical shaft furnace, the wet green balls are distributed evenly over the top of the slowly descending bed of pellets...The ball formation occurs because of the surface tension of the water forces and collision between particles. Initially, small nuclei of pellets are formed on addition of w ater and the nuclei grow bigger into balls and then into pellets as the peak of loose grain pa rticles during their travel through the drum which is slightly tilted.

These green balls are subjected to drying (280–340°C), preheating (350–900°C), firing (900–1330°C), and cooling (1330–100°C) in the induration furnace where pellets are in directly heated in a controlled manner by circulation of hot gases with the help of process fans...The process stages for production of pellets from iron ore fines consists of grinding of ore fines (Feed preparation),Iron ore slurry handling, filtration of iron ore slurry and producing filter cake, formation of green balls and Induration of green balls to convert into pellets.
