    These material screening devices prevent oversize muck from entering the ore pass. The most common types of these screens are grizzlies and scalpers, although scalpers tend to experience greater amounts of oversize blocks wedging between bars, resulting in higher maintenance costs. In the use of scalpers, it is common for operating crews to push the oversize through the scalper, this practice

    Screening ScienceDirect

    01-01-2016· Separations of dry materials by screens and sieves are generally attempted down to about 75 μm. Finer materials have a tendency to blind the sieve openings. In such cases, screening in the presence of water helps. Separations of even finer sizes are difficult on a sieve. For such fine material other processes have to be adopted such as

    Sintering: A Step Between Mining Iron Ore and

    World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
