In term
of mining machine, crusher is known as a
huge equipment or machine which is functioned to break the big rocks into the
smaller ones and even gravel and dust. In
general, it is a way to reduce the size of rocks so that it can be more easily
to replace, recycle, and also dispose. Sure, it is very important for several
kinds of industry, particularly mining, metallurgy, transportation, energy,
materials. Since you can classify it as heavy equipment, it is really effective
to break and crush a very solid and high hard material. However, for some
matters, the crusher is also useful to crush the softer ones like iron ore,
limestone, marble, granite and some others. There are many types of crushers
along with the functions. Some of them will be described as follows.
Jaw Crusher
Jaw
crusher is probably the most common crusher type tp be used. It is due to its
working system pressing the materials unti they are crushed. It is generally
used to break the rocks with really hard structure. However, for its ability,
jaw crusher tends to be more flexible as well. Yes, it is also quite helpful if
you want to crush other materials which are softer or smoother.
Roll Crusher
Roll
crusher is a kind of crusher machine that works by applying the rotary rolling
system with acceleration of rpm which tends to be slow. Roll crusher is very
common to be used in the world of mining. It is for crushing the rocks with the
level of hardness which is relatively low like ore, limestone, and materials
for cements, copper, sulfur and many more.
Impact Crusher
Impact
crusher is in general just the same with the roll crusher. However, the
acceleration applied is relatively higher than the roll crusher. Based on that
fact, the materials that can be crushed using this machine tend to be more
various also even those with high level of hardness. In the world of mining and
industry, impact crusher is common to be used to break the stones on the river
or volcano rocks which are indeed known as a sort of really hard materials.
Hammer Mill
This is
basically similar with impact crusher in which it works with the principle of
rotary system with a very high acceleration. Besides, it also works by punching
the materials that will be crushed. Hammer Mill machine is very effective to
form smooth sand, mineral concentrate, ore mineral, and other kinds of powder
from rocks, let’s say the dolomite, zeolite and some others.
Hammer Roller Mill
Hammer
Roller Mill is basically the combination of hammer mill and roll crusher. The
way it works is by punching the materials hardly with high acceleration and
then rolling it just like the roll crusher. This machine is very effective to
produce concentrate from the mineral rocks with high levels of hardness. Then,
it is really capable to make powder with high level of softness as well. This
kind of crusher is very appropriate for the
mining of gold and copper as well as the production of fertilizer.
