Iron refined powder
Beneficiation of iron ore after crushing, grinding, such as processing ore called iron refined
power.
Concentrate In accordance with processing method is divided into a variety of fine Mineral
Powder, such as magnetic separation, flotation concentrate such as, re - election.
We can guarantee 64 per cent iron content in iron concentrate powder products, and S,P,SiO2
and other impurities less.Determination of acidity and alkalinity of iron ore :
According to the ore (CaO+MgO)/SiO2+Al2O3 ratio, you can determine the acidity and
alkalinity of ore :(CaO+MgO)/SiO2+Al2O3 US ore properties
<0.5 US acidic ore
0.5-0.8 US and a half from molten ore
0.8-1.2 US Self - fluxing ore
>1.2 US alkaline ore
Anthracite
Commonly known as White coal or coal. Coal is the largest degree of coal.
Anthracite fixed carbon content, volatile low yields, density, hardness, and ignite high,
not smoke when burned.Black hard and metallic. To fat friction does not pollute,
fracture - shaped, short burning flames and smoke less.No coke. More than 90 carbon
content in general, volatiles under 10.No thickness of plastic layer.
Calorific value of about 6000-6500 kj/kg.
Sometimes called semi - volatile content of large anthracite ; called high - anthracite small.
Anthracite Coal level of the deepest coal, the most carbon content, ash content not much,
less moisture, high calorific value, up to 25000~32500kj/kg, volatile release of high temperature,
its coke not tack, fire and Burns are difficult, burning smokeless flame is blue.
Cut off from the air under the conditions of Coal Sample heating, thermal decomposition of organic
matter in coal liquid molecular weight of some of the smaller ( at which point to the steam State )
and gaseous products, these products are called volatile.Volatile coal yield of quality scores to be volatile
or referred to as volatile.
To dry, ash - free base for the analysis of the base, less than 10 of coal volatiles are called anthracite.
Volatile anthracite called anthracite third number greater than 6.5 and less than 10. No. 01 anthracite
for older anthracite ;no. 02 anthracite for typical anthracite ; no. 03 anthracite for young anthracite.
Anthracite Coal is the main application of fertilizers ( nitrogen, and ammonia ), ceramics, manufacturing
forging industry ; smokeless powder coal mainly used in the metallurgical industry for blast furnace injection
(Blast furnace coal injection includes anthracite, coal, coal and gas coal).
