Sinter Plant an overview ScienceDirect Topics

Feb 03, 2012· Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site. Some works have both pelletizing and sintering plants at the smelter sites. 1.1.3.2.2.2 Green Pellets. The ore is crushed, ground, and concentrated in several steps to very small grain size—e.g., over 75% less than 45

Rawmill Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

Ore Beneficiation an overview ScienceDirect Topics

The required P 80 of the ore, in order to achieve adequate liberation, is 40 μm. This plant uses a vertical stirred mill after AG rather than a ball mill to achieve this fine grind size with an energy cost saving of 35% or better (Arvidson, 2013). An important part of the comminution circuit is size classification.

Pelletizing Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of

The Sintering Process of Iron Ore Fines IspatGuru

Mar 09, 2013· The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.

Manufacturing process Lafarge Cement, concrete

The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
