Mineral liberation studies of IMPTEC super-fine crusher

Low-grade magnetite ores are typically fine-grained and require fine to ultra-fine grinding (P80 ~ 30 40 µm) to enhance its liberation from the typically siliceous gangue matrix. Historically, this has been achieved using multi-stage crushing and grinding technologies, which require high energy consumption with low energy efficiency.
