Chromite ore processing vertical roller mill
Chromite sand, chromite powder is natural chromite product after milling machining process, etc. by crushing and screening, chromite powder heated volume stability, high thermal conductivity, anti-sintering, refractory, high temperature improve the high temperature coefficient of friction, reduce wear and significantly improve the thermal degenerative characteristics.
Chromite sand, chromite powder Uses: suitable for casting coatings, refractory materials, automobile brake linings, high-performance ceramic materials, ceramic, glass coloring agents, friction materials, chemical and metallurgical casting and other fields.
Chromite sand, chromite powde grinding and crushing machines：
PE series and PEX series Jaw crusher
PC hammer crusher
YGM high pressure suspension vertical mill
HGM series vertical roller mill(main product)
>>HGM chromite vertical roller millapplications:
HGM chromite vertical roller millis mainly applied to non-inflammable, non-explosive and brittle materials with Mohs’ hardness scale under seven, such as calcite, chalk, limestone, dolomite, carbon black, bentonite, kaolin, talc, mica, magnesite, illite, pyrophyllite , roseite, sea-foam, attapulgite , rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, kalium ore, pumice etc. totally more than 100 kinds of materials.
Finished powder products are in the 325meshs -3000meshs, and yield can be up to 0.5-12 tons per hour.
>>HGM chromite vertical roller millsupplier:
There are five types of HGM chromite vertical roller mill that supplied by Shanghai CLIRIK machinery co., lt. They are HGM series grinding mills HGM80, HGM90, HGM100, HGM100A and HGM125.
>>HGM chromite vertical roller millproduction line:
The whole setHGM chromite vertical roller millconsists 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.
>>HGM chromite vertical roller millfeatures:
1. High efficiency
Under the same final size and power, the product capacity of Vermiculitegrinding millis twice than jet mill and agitation mill.
2. Longer lifetime of spare parts
The roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach 2-5 years.
3. High safety and reliability:
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen.
4. High fineness of products
The product fineness can reach D97≤5μm.
5. Environment friendly
The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.
>>HGM chromite vertical roller millworking 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.
