High Fineness Unscreened Crushing Line product description
The high fineness non-screening crushing
production line consists of raw material silo, vibrating
(screening) feeder, jaw crusher, toothed roll crusher (cone crusher
according to customer's requirements), two roll crushers, suspended
permanent magnetic iron remover, several belt conveyors, dust
collection system and electric control system. It is characterized
by no screening, low running cost, no fear of moisture, large
output, low power consumption and less dust. It is a rare and
mature high fineness non-screening production line in today's
domestic market.
It can be used for crushing all kinds of
stones with compressive strength less than 300Mpa, such as
limestone, dolomite, river pebbles, granite, basalt, quartzite,
potassium feldspar and so on. It is mainly used in building
materials, coal water slurry, iron and steel, thermoelectricity,
chemical industry, etc., especially when the material humidity is
very large (viscous) can not be screened occasions.
High Fineness Unscreened Crushing Line working principle
When the high fineness non-screening crushing production line is
working, turn on the electric control system according to the
sequential order, start all the equipments, use the loader to pour
the large stone into the raw material warehouse, then the vibrating
screen feeder (connected with the suspended permanent magnetic
separator at the material drop) will firstly send the stone (mixed
with clay) and so on into the jaw crusher by the belt conveyor for
coarse crushing, and the coarse crushing will be crushed to 120mm,
and then sent into the toothed-roll crusher for secondary crushing
(middle crushing) by the belt conveyor through the fabricator to
the 1# roller crusher for fine crushing to 8mm or so. Crusher for
secondary crushing (medium crushing), medium crushing to about
40mm, from the belt conveyor through the fabricator into the 1 #
roller crusher for fine crushing to about 8mm. And then by the belt
conveyor through the fabricator into the 2 # roller crusher for
fine crushing to about 2mm, without screening equipment, that is,
to achieve about 98% of the finished product rate.
If the silica content of the stone is
too high, when the roll surface is worn out faster, the roller
surface grinding (cutting) device is configured, and the roller
surface is repaired with the grinding device at any time according
to the roller surface condition, and the granularity requirement is
guaranteed at all times.
The capacity of high fineness
non-screening crushing production line can be designed according to
the customer's requirements, configured with different models of
equipment, in the discharge size of about 2mm non-screening, a
single production line can reach 10-300t / h. The production line
can be equipped with dust collector according to the customer's
requirements.
According to customer's requirement,
this production line is equipped with dust collector, i.e. the dust
collector is added in the feeding and discharging ports of jaw
crusher, the feeding and discharging ports of toothed roll crusher
and the feeding and discharging ports of the two roller crushers,
and the high negative pressure of the dust collector's fan is
utilized to adsorb the micro-fine particles on the bag, and the bag
is automatically vibrated and cleaned up regularly, so that the
dust is collected and meets the national environmental protection
standard.
