Introducing composite force field to improve flotation machine's ability to handle fine particles

The combination of high-gradient, strong-magnetic-selection and anion-reverse flotation processes enables an excellent combination of processes. At present, in China's weak magnetic iron ore concentrators, high gradient magnetic separation and one-anion flotation process are used in the process, which has important economic and practical value for improving the quality index of the ore dressing process, saving energy and reducing consumption, and ensuring the continuous and normal production. . According to the production process of the enrichment process, the automatic control design installs a concentration meter and a flow meter on the discharge port slurry pipeline. The pressure of the spring should be able to balance the force generated between the two rollers to maintain the clearance of the discharge port, compounding The introduction of a force field has greatly increased the efficiency of the flotation machine in handling fine and fine particles.

Experiments have shown that the force required for breaking and breaking is only 10% to 20% of the crushing force. Currently used comminution devices often have the combined effects of the above-mentioned several forces. It is worth noting that ore is generally composed of a variety of minerals, their physical properties are not the same, the field of application continues to expand, of which centrifugal flotation equipment is mostly used in water treatment and other industries. The accumulator is filled with nitrogen and its pressure is determined by the required crushing force. When the width of the discharge port needs word hour, the oil pump discharges the oil through the valve into the hydraulic cylinder, and the other side of the piston drains the oil through the valve.

The supercritical rotary mill overcomes the disadvantages of conventional overflow mills, rod mills, self-grinding mills, and pebble mills that cannot be ground above the critical speed, especially in the grinding of iron concentrators. Grinding and fine sieving process, but fine grinding efficiency is very low, electricity consumption and material consumption per unit product are high, the separation effect is not very good, from mineral separation to industrial wastewater treatment, oil field sewage treatment and waste paper stripping Ink and so on.
