Taconite is a variety of iron formation, an
iron-bearing (> 15% iron) sedimentary rock, in which the iron minerals are
interlayered with quartz, chert, or carbonate. The iron content of taconite,
commonly present as finely dispersed magnetite, is generally 25 to 30%.
Recently, lots of customers have inquired about the taconite crushing equipment
made by ZOONYEE. As a professional manufacturer of mining equipment, ZOONYEE
always holds the belief that we should offer all-round mining solutions for our
honored customers. And then let us have a look at more details of taconite
crushing equipment and taconite mining equipment.
Analysis
of Taconite Mining Industry
Taconite is a low-grade iron ore. When the
high-grade natural iron ore was plentiful, taconite was considered a waste rock
and not used. But as the supply of high-grade natural ore decreased, industry
began to view taconite as a resource. Many professors, along with other
scientists and engineers, conducted years of laboratory tests and experiments
to find a way to take the iron ore out of the taconite rock. After many years
of hard work, a process was developed to create taconite pellets. Taconite
saves the iron ore mining industry in the world. Therefore, a new era of
taconite is coming, and the prospect of taconite mining industry is very
inspiring.
Flowchart
of Taconite Mining Equipment
The mining flowchart of taconite can be
divided into the following stages:
·
Blasting:Taconite
is a very hard rock. Using explosives, the taconite is blasted into small
pieces.
·
Transportation:The
taconite pieces are scooped up by electric shovels. Each shovel can hold up to
85 tons of rock! The shovels place the taconite into giant dump trucks. These
trucks are as big as a house and hold up to 240 tons of taconite. The trucks
take the taconite directly to the processing plant, if it is nearby, or to
train cars if it is far away. Besides, the belt conveyor is always used as the
conveying system in the taconite quarry.
·
Crushing:At the
processing plant, the taconite is crushed into very small pieces by rock
crushing machines. The crushers keep crushing the rock until it is the size of a
marble. The rock is mixed with water and ground in rotating mills until it is
as fine as powder. As for the taconite crusher, it contains the jaw crusher, impact crusher,
and other types of crusher. If necessary, the mobile
crusher is also used as the taconite crushing equipment.
·
Separation:The
iron ore is separated from the taconite using magnetism. The remaining rock is
waste material and is dumped into tailings basins. The taconite powder with the
iron in it is called concentrate.
Taconite
Crushing Equipment—PEW Jaw Crusher
Typically, taconite crushing equipment refers
to crushing machines used in the crushing process of taconite rocks. Jaw
crusher is often used as primary taconite crushing equipment in the process of
taconite mining. It has been proved that PEW Series jaw crusher produced by
ZOONYEE performs as an efficient machine when processing taconite rocks. PEW
series jaw crushers have wide applications, used in the metallurgical industry,
mining industry, construction and chemical industry. The anti-pressure of PEW
jaw crusher can achieve to 280Mpa, and the feeding size can reach 930mm.
Meanwhile, world-class manufacture crafts and high-tech materials are adopted
in the PEW Jaw crusher, which makes it very suitable for the situation of
taconite mining industry.
