The brief of Cone crusher
Cone crusher
can be regarded as one of the most popular crusher machines actually
since it is widely used in construction, chemical and silicate industry
for crushing raw materials and so forth. You can crush all kinds of ores
and rocks with different sizes easily with the use of such machine
actually. It has very high working efficiency, as well as the low energy
consumption. Cone crusher is one hundred years later than the roll
crusher, and is 20 years later than gyratory crusher. Before the coming
of the cone crusher, in the early 20th century hydroxide method has
great development, it is required to provide more fine products than
gyratory crusher and jaw crusher.
The development of Cone crusher
In 1927, the cone crusher which has slowly inclined
cone is formally used in industry. This kind of cone crusher includes
Simon type standard and short head cone crusher and spherical cone
crusher. The characteristics of them are that their moving cone is
slowly inclined, and they both have the spring overload protection
device.Before long, steep inclined compression cone crusher also
appeared, started this crusher is called compression gyratory crusher,
essentially the crusher is modified on the basis of the gyratory crusher
which was used for beaking to the size between crushing and finely
break. Its shape and structure wre the same with the short axis gyratory
crusher, with a very steep cone, small row, short spindle , big
stroke, high speed.In the late 50 s, hydraulic technology began to been
widely used in cone crusher of the various countries' manufacturing ,
and further improved the cone crusher. The slow cone crusher adopted
hydraulic or pneumatic to adjust the rowing ore mouth installation, and
also hydraulic overload protection device and hydraulic lock device on
the basis of keeping the original spring gentle cone overload protection
device.Meanwhile, steep taper cone crusher in retain the original steep
cone, also used the hydraulic pressure technology. According to the
difference of its hydraulic setting place, it can be divided into the
bottom of the hydraulic support type or the type hydraulic hanging at
the top of the cone crusher. Due to row ore mouth and overload
protection device adopted hydraulic system regularly, the structure, was
simple, the operation was reliable.In the 70 s, cone crusher, made
progress in two aspects. One is the appearence of the 3050 mm large cone
crusher, the other one is the appearence steep cone crusher and gentle
taper cone crusher which can produce the fine materials. The latter has a
new type of crushing cavity structure, main shaft of which is short,
and it can obtain 4 purpose material characteristics.
The types of Cone crusher
Cone crusher by the above two kinds of different types,
derived some other types, such as multi-cylinder hydraulic crusher
without gears. The multi-cylinder crusher in fact is only used for
locking device, which can not be mentioned in the same breath with
single cylinder at the bottom of the hydraulic breaker and top single
cylinder hydraulic crusher. In past the classification or term was based
on the hydraulic and spring, some was based on medium, short head,
spherical.
