Iron Ore Processing Equipment
We designed this impressive iron ore screening plant to produce around 90 million tons of iron ore annually. The Niagara F-Class 2440×9760 (8`x32`) vibrating screens and Niagara XL-CLASS 12'x28' for the primary screening (cutting in 90 mm) pictured are in operation today, and efficiently process the cut sizes of 40 and 19 mm.
Version 1
As with other ore screening processes, abrasion can become a problem depending on ore quality, and blinding is always an issue if the final separation is too small. solutions Rubber screening media are a good choice for pre-heap leach. MP for separations of 40 mm and higher are ideal for the primary screening side. For

High Tramp metals in our ROM ores Damaging Our Primary …
Spotters are cheaper at Porgera but very hard to spot a broken tooth, tramp magnets are great with a belt feed but obviously have issues if there is much magnetite in the ore, probably no need for detectors as a good magnet will find most of it. If the loader and excavator tooth is common - that needs to be addressed on its own with the vendor.
Crushing Plant Design and Layout Considerations
Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.
