Log Washersare used in a variety of material processing applications and are best known for their ability to remove tough, plastic clays from natural and crushed gravel, crushed stone, and ore feeds. One limitation of Log Washers is that they must have a controlled top size. In general, most units can accept feed material up to 4” (100mm) cubed, th...

Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.احصل على السعر
