The disc feeder is a common equipment used to evenly feeding medium- and fine-grained materials. It mainly allows the materials in the silo to be discharged and fed into the next equipment continuously and evenly, saving labor. It is usually suspended on a steel structure or installed at the discharge port of a hopper or silo for continuous feeding.

For graphite ore beneficiation, graphite ore has good conductivity, while gangue minerals such as feldspar, quartz, pyrite, etc., have poor conductivity. The effective treatment particle size of the electric separation method is usually 0.1-2mm. However, the upper limit of processing particle size can reach 5mm for flake or low-density graphite ...

♦ Washing process. If the surface of the raw material contains soil, mud, or other impurities, log washer, trommel scrubber, and other ore washing equipment are often used to clean and screen the ore.. ♦ Crushing, grinding and classification process After the large ore is crushed to reduce the ore particle size, the concentrate and gangue minerals are simply dissociated.

Tungsten ore is mainly divided into scheelite and wolframite.Wolframite is the oxide of tungsten, and scheelite is calcium tungsten. Although scheelite reserves are large, there are fewer rich ores, lower grade, and more difficult-to-select ores, so the mining volume only accounts for about 10% of tungsten ore production.
