In recent years, the rapid development of private small and medium-sized iron processing plant. Small investment in these small business quick, and some small mines 6 months to recover all investment, one of the important reasons is the use of two high efficiency three millway Wei low consumption of new technology. The so-called iron mill two mill three sieve efficient book can consume low-cost new technology (hereinafter referred to as two mill three sieve new technology), that is beneficiation workshop in the same axis according to the process elevation requirements of two mill layout,
