Chromites are also called chrome iron ore, or chromic iron ore. It is an oxide mineral belonging to the spinel group. Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite; substitution of aluminium occurs leading to hercynite.
Chromites should be crushed or pulverized to grain or powder after mined and separation. The common pulverizer and crusher line is HGM and YGM series grinding mill plant.
Finished powder products are in the 325meshs -3000meshs, and yield can be up to 0.5-12 tons per hour.
>>Chromite/chrome iron ore/chromic iron ore grinding mill supplier:
There are five types of chromite/chrome iron ore/chromic iron ore grinding mill that supplied by Shanghai CLIRIK machinery co., lt. They are HGM series grinding mills HGM80, HGM90, HGM100, HGM100A and HGM125.
>>Chromite/chrome iron ore/chromic iron ore grinding mill production line:
The whole set chromite/chrome iron ore/chromic iron ore grinding mill consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.
>> Chromite/chrome iron ore/chromic iron ore grinding mill working Principle:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse powder return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
