Mohit Kumar, Terex, India, considers some solutions to the most significant crushing and screening challenges faced by the mining industry today – with a particular focus on iron ore mining in India.
O
ne of the main challenges faced by the mining industry in terms of crushing and screening includes the feed material itself, which often has a high moisture content and therefore requires an aggressive screening box design. It also encounters a high quantity of fines (approximately 40 – 50%), which means equipment should have a large screening area and various screen media
options to address this. Additionally, precise end-product specifications are required, such as 5 – 18 mm or 10 – 30 mm, that can be used as iron ore lumps in the blast furnace or for direct reduced iron (DRI) steel processing. Given the huge scale of mining sites, equipment must be transported regularly, which gives mobile crushing and screening machines a competitive advantage over static plants.
